STM32W RF Port

Question asked by Bertrix on Sep 4, 2013
Hello,

The STM32W wireless microcontroller has a balanced RF port. Is it possible to use this port in a single ended way for low-cost space-constrained applications?

I would terminate RF_N with a 50ohm resistor and DC block capacitor. The RF_P pin would be connected to a PA/LNA frontend. There is a 2.4GHz bandpass filter after the PA so extra harmonics should not really be a problem.

Can this work, or should I design in a balun?

Sincerely,
Bertrix
