Sure, I can assist you in organizing a component list and propose a simple schematic for a portable network booster. Given the components you have suggested:

RF Transistor: BFY90 or BFY51

Filters

Matching Networks

Power Supply

Heat Sink

Variable Attenuator (Optional)

Here is an approximate schematic outline:

RF transistor (BFY90/BFY51)
- This will be used as your amplifier in the circuit.

Filter
- This goes to the output of your RF transistor to reduce noise.

Matching Networks
- This is needed to match the impedance between your RF transistor and the filter.

Power Supply
- This provides power to your RF transistor and other components if needed.

Heat Sink
- This is attached to your RF transistor to dissipate heat.

Variable Attenuator
- If included, this can be used to control the signal power level.

Without more specific details, I'm going to propose a general connection list, but please modify it according to your actual needs:

Power Supply to RF Transistor:
- Connect PSU:Vout to Q1:Vcc

RF Transistor Output to Filter:
- Connect Q1:Out to Filter:In

Filter Output to Variable Attenuator (Optional):
- Connect Filter:Out to VAR:In

Variable Attenuator to Output Connector:
- Connect VAR:Out to CN1:Signal

Please note that the actual schematic and the connections would depend on the specific functional blocks' requirements and the chosen component models.

which is the best filter to use can i use a capacitor

11mo

copilot

In RF circuits, it is generally more common to utilize a series of inductors (L) and capacitors (C) arranged strategically to form what is known as an LC filter. Simply using a single capacitor to filter the output of an RF amplifier may not be very effective in filtering out unwanted frequencies. LC filters are used in RF circuits due to their ability to operate over a range of frequencies and their capability to handle high voltages and currents.

However, it's also important to note that filters' choice is highly dependent on your specific needs. In particular, you'd want to consider the frequency of operation, the power level, the desired level of noise attenuation, and the specific unwanted frequencies you want to filter out.

For a more elaborate response, could you provide more information about these parameters? If these details are not available, I suggest consulting with an RF engineer or utilizing an RF design software to assist in selecting the appropriate RF filter for your network booster.

i am filtering out noise from aroundc 1800ghz and 70dbm power

11mo

copilot

To filter out noise around 1800 GHz (Gigahertz), you need a specialized filter called a Bandpass Filter, which only allows frequencies in a specific range to pass and attenuates frequencies outside this range.

A note on your power requirement: 70 dBm corresponds to 10,000,000 Watts, which is an exceptionally high-power level in the context of electronic circuits. This might not be possible to achieve with consumer-level components, and it might potentially be a safety hazard. Please confirm if this is indeed the required power level for your application.

For this context, let me assume you're working with a lower power level, say around 0 dBm (1mW).

Here's a general suggestion for your RF part:

Low-pass L-network: The inductor (L1) and the capacitor (C1) form a low-pass filter; this matches the impedance and filters the output of the RF Transistor. Select the values of L1 and C1 based on your impedance requirements and frequency of operation (1800GHz).

Bandpass filter: The second inductor (L2) and second capacitor (C2) create a band-pass filter that isolates the 1800GHz signal.

A potential connection list for your circuit might look like this:

Connect Q1:Emitter to L1:1.

Connect L1:2 to C1:1 and to filter:IN.

Connect C1:2 to GND:1.

Connect Filter:Out to Amp:In.

Please adapt these guidelines to fit your design in Flux, as the design would depend heavily on the models of components and their specifications. Selecting these components and designing these filters requires careful calculations and considerations beyond simple rule-of-thumb estimates. If you don't have strong expertise in RF design, consider consulting with an RF engineer.

sorry imean -70dbm

copilot

Great. A power level of -70 dBm (around 0.1 nW) is much more common in RF circuit designs.

For blocking out noise around 1800 GHz with this power level, the components in your design wouldn't need to handle high power, allowing you to use common components.

You can proceed with the schematic design proposed before - with the RF transistor, filter, matching networks, and variable attenuator appropriately designed for handling -70 dBm at 1800 GHz.

For your RF filtering needs, an RF bandpass filter centered at 1800 GHz would be ideal. These can be designed using radio frequency components like resonators, capacitors, and inductors. However, specific RF filter design at this frequency is quite advanced and typically would require specialized RF simulation and design tools.

Remember that filtering and amplification at such frequencies requires precision, and both the PCB material and layout can have a big impact because of parasitic inductance and capacitance.

If you're not experienced with working on high-frequency RF designs, it may be best to consult with an RF engineer or consider premade filter modules that operate in your desired frequency range.

I understand that you're looking for recommendations for certain components. Here are general recommendations based on typical setups:

RF Transistor: Both BFY90 and BFY51 are suitable NPN transistors for RF applications. Your specific choice will depend on the operating frequency and output power requirements.

Filters: For RF applications, you might consider ceramic filters, surface acoustic wave (SAW) filters, or lumped elements (inductors and capacitors) based filters, which are typically used for IF and RF filtering. Again, your choice should be largely based on the frequency and the bandwidth requirements of your application.

Matching Networks: Matching networks are designed according to the impedance of your load and source. They typically consist of passive components such as resistors, capacitors, and inductors. An LC circuit or a Pi network can be a good starting point.

Power Supply: The power supply requirement would depend on the biasing needs of your RF transistor. For instance, if you're using the BFY51 transistor, a power supply of around 12V would typically be sufficient.

Heat Sink: An appropriate heat sink would depend on your power requirements and thermal conditions. You can use an aluminum heat sink that can handle your device's highest operating temperature and power dissipation.

Variable Attenuator: A variable attenuator such as a voltage variable attenuator or a digital step attenuator would be suitable for applications requiring changes in signal strength.

Please remember that these are just general guidelines. Your specific requirements, such as the working frequency, power level, environment conditions, and physical space, will likely refine these choices. Be sure to consult your project's exact requirements before making final selections.

@copilot como hacer un amplificador de sonido para una bocina de 8hm

copilot

Para hacer un amplificador de sonido para un altavoz de 8 ohmios, puedes usar el amplificador integrado LM386N-1/NOPB mencionado en tu proyecto. El LM386 es un amplificador de potencia de baja tensión diseñado para aplicaciones de audio.

Esquemáticamente, aquí se muestra una conexión básica:

V+ (Pin 6) - Conecta este pin al suministro de energía de DC. Rango aceptable de voltaje para LM386 es entre 4V y 12V.

GND (Pin 4) - Conecta este pin a la terminal de potencia negativa de tu fuente de energía o común.

Entrada de audio (-) (Pin 2) - Esta es la entrada de audio no invertida. Puedes conectar tu fuente de audio aquí.

Entrada de audio (+) (Pin 3) - Esta es la entrada invertida de audio. Normalmente, este pin se conecta a tierra para operaciones de un solo extremo.

Salida de audio (Pin 5) - Conecta este pin a tu altavoz de 8 ohmios. Recuerda que posiblemente necesites un condensador electrolítico en serie (alrededor de 220uF). El terminal positivo del condensador debe estar conectado a este pin y el terminal negativo al altavoz.

BYPASS (Pin 7) - Este pin puede ser dejado sin conectar para ganancia de 20, pero si necesitas una ganancia de 200, debes conectar un condensador de 10uF entre este pin y tierra (GND).

GAIN (Pin 1 y 8) - Connect these pins with a capacitor (10uF) for a gain of 200.

Ten en cuenta que la conexión exacta puede variar de acuerdo a tus especificaciones exactas para ganancia, regulación de bajo, etc.

Y siempre se recomienda revisar y seguir el datasheet del fabricante.

Este es un ejemplo para una conexión básica y no incluye consideraciones para oscilaciones, ruido y estabilidad del circuito que se pueden deber manejar adicionalmente.

como hacer un amplificador de sonido para una bocina de 8hm con un potenciometro

copilot

Puedes usar el LM386N-1/NOPB que ya tienes en tu proyecto con la incorporación de un potenciómetro para el control de volumen. Aquí se detalla una conexión básica para este diseño:

Entrada de energía V+ (Pin 6): Conecta este pin a la fuente de energía de DC. LM386 puede funcionar con un rango de voltaje de 4V a 12V.

Tierra GND (Pin 4): Conecta este pin a la terminal de tierra o negativa de tu fuente de energía.

Entrada de audio (-) (Pin 2): Conecta este pin a uno de los terminales del potenciómetro. Este será la fuente de audio.

Entrada de audio (+) (Pin 3): Conecta este pin a Tierra para configurar el amplificador en Modo Single-ended.

Salida de audio (Pin 5): Conecta este pin al altavoz de 8-ohm. Podría necesitar un capacitor en serie (alrededor de 220μF) para eliminar cualquier DC. Conecta el terminal positivo del capacitor a este pin y el terminal negativo a la bocina.

BYPASS (Pin 7): Este pin puede dejarse sin conectar para una ganancia de 20, pero si necesitas una ganancia de 200, puedes conectar un condensador de 10μF entre este pin y la tierra (GND).

GAIN (Pines 1 y 8): Conecta un condensador de 10μF entre estos pines para una ganancia de 200.

Potenciómetro: El primer terminal va a la fuente de tu señal de audio, el terminal del medio (cursor o corredera) va al pin 2 (entrada de audio -) del LM386, y el último terminal se conecta a tierra (GND).

Por favor, revisa el datasheet del LM386 para entender completamente cada pin y cómo afecta al circuito. Este es un diagrama básico y podría requerir refinamiento y ajuste de acuerdo a tus necesidades y preferencias específicas.
