Re: confused about S11
But who can tell me whether the second amplifier could be used in real design when it is a LNA connected after antenna with good noise figure and enough gain but bad S11?
Re: confused about S11
if the two amplifiers are both Low noise amplifiers,connected after antenna,will the same power be obtained at the output of low noise amplifier?
confused about S11
There are two amplifiers whose parameters are as follows:S11A=-20dB，S21A=10dB；S11B=-2dB，S21B=10dB.
If they are connected between RF ignal source (if available power equals 0dBm) and Spectrum Analyzer respectively, is 10dBm displayed on Spectrum Analyzer ?(becasuse when...
