# RFFM6901 (Component) ## Description The RFFM6901 is a single-chip RF front-end module (FEM) designed for 868 MHz to 928 MHz ISM-band wireless communication applications. It integrates a high-power power amplifier (PA), low-noise amplifier (LNA), antenna diversity switch, and matching circuitry into a compact package, helping reduce external components, PCB space, and overall system cost. It is commonly used in smart energy systems, wireless metering, industrial monitoring, alarm systems, and other Sub-1 GHz wireless devices. Key Features Operating frequency range: 868 MHz to 928 MHz Integrated 1 W power amplifier Up to +30 dBm transmit output power Integrated low-noise amplifier with bypass mode Dual-port antenna diversity switch Separate 50 Ω transmit and receive interfaces Compact 32-pin LGA package (6 mm × 6 mm) Supply voltage range: 2.8 V to 4.2 V Typical LNA gain: 17 dB Low receiver noise figure: 1.5 dB Designed for portable and battery-powered wireless systems RoHS compliant Typical Applications Smart energy and smart metering Wireless alarm and security systems ISM-band communication devices Industrial wireless sensors Portable RF equipment IoT Sub-1 GHz wireless systems Search across more sources ## Component Details - **Owner:** adrian95 - **Created:** 5/8/2026 - **Last Updated:** 5/8/2026 - **Visibility:** Public - **Max Current:** 450mA - **Operating Temperature:** -40 to +85°C - **Compliance:** RoHS, Lead-Free, Halogen-Free; ECCN EAR99; ITAR No - **Package or Case Code:** LGA-32 - **Manufacturer Part Number:** RFFM6901 - **Part Type:** RF Front-End Module - **License:** https://creativecommons.org/licenses/by/4.0/ - **Datasheet URL:** https://www.mouser.com/datasheet/2/412/RFFM6901%20Data%20Sheet-1112583.pdf?srsltid=AfmBOoqj8mf54pxk7pxdUgXxEFk4Fy3fEp9k6zKXymx2RuhPXghgk__x - **Frequency:** 868–928MHz - **Operating Voltage:** 2.8–4.2V - **Manufacturer Name:** Qorvo - **Implementation Details:** Discontinued product. 50Ω RF ports.
