Medium power bidirectional amplifier design

Wireless Connectivity Matter
1

I am designing a bidirectional medium power amplifier for an active antenna.
One of the design challenges is the effect of the Tx output amplifier noise on the receiver sensitivity; given the limited isolation of the Tx/Rx switch.
Working with your QPA9942, I want to know its noise figure in the frequency range 3.55 to 3.74 GHz.
