Hi all,
I have simulated Qorvo TQL9044 LNA (internally matched for 1.5GHz to 4GHz band).
At 5.2GHz (out Band), simulation responses are :
S11 (IRL) is -0.47dB; S22(ORL) is -5.8dB and S21(gain) is -4.96dB.
Question: If I feed -20dBm as input power to this LNA at 5.2GHz then what will be the output power? Will it be -24.96dBm (-20dBm -4.96dB) or nil output as IRL is nearly 0dB.
Pl reply
Regards
