Yes. we checked for all input power range. from small to 15dm but for all of them, S21 was similar. it didn't matter the input was 1dbm or 15dbm, S21 was same.
thanks a lot for your reply.
The bias voltage is 1V and the current is 19mA and its close to what i had simulated or in the other word bias measurement is close to simulation.
Thanks a lot for your reply but i should mention that this is measurement and not simulation. the circuit is fabricated in 28nm TSMC technology and S parameters are real measurements. so do you think the measurement may have problem and not the circuit? Do you think the calibration of...
Hi:
recently i have measured my mw-lna but i think that something is wrong with the output S parameters. i put the output results. do you think S parameters are normal? does amplification happen? is the LNA stable? or its a normal failed LNA? can you find the problem by just looking at the S...
