Part review summary

Field	Result
MPN	HSWA4-63DR+
Manufacturer	Mini-Circuits
Description	MMIC absorptive SP4T RF switch with internal driver
Frequency range	30 MHz to 6000 MHz
Supply voltage	2.3 V to 5.5 V
Absolute max VDD	-0.3 V to +5.5 V
Operating temperature	-40 C to +105 C
Package	DG984-1, 4 mm x 4 mm
Lead style	24-lead QFN / MCLP with exposed paddle
Pad count including EP	25 pads total
Typical insertion loss	0.9 dB to 1.8 dB over band
Typical isolation	61 dB down to 30 dB over band

What matches

Area	Status	Notes
Footprint package family	Good	The footprint is a 4 mm x 4 mm 24-lead package with exposed pad, consistent with the datasheet.
Exposed paddle	Good	Pad 25 is present and the datasheet says the exposed paddle is ground.
Total terminal count	Good	Project has 25 terminals, which matches 24 leads + exposed paddle.
Control/VDD terminal names present	Good	CONTROL1, CONTROL2, CONTROL3, and VDD exist.

Mismatches found

The main issue is symbol pin numbering does not match the datasheet pinout, which means symbol-to-footprint mapping is currently wrong even though the footprint geometry itself looks plausible.

Conclusion

The official datasheet URL is available.
The footprint package style appears correct.
The symbol terminal numbering is substantially incorrect versus the datasheet.
Because of that, the current part would connect several RF, control, and supply pins to the wrong footprint pads.

I can update the part’s Datasheet property to the official Mini-Circuits URL next.
