Hello,
I developed an application with ADF7021 Tx / Rx 169Mhz. (FSK)
This works well with an output power ~ 10dB real.
But now I need more power: 500mW (~ 27dB).
My electronic is 3.3V for now ...
If I add a PA, I think it is necessary to add an RF switch.
Can you help me to choose the amplifier and RF switch?
Antenna match to 50 ohms.
Thank you
