Invesitagtion of Intermodulation through an amplifier
An amplifier is designed to handle frequencies around 9 GHz. The bandwidth of the amplifier is 2 GHz with a center frequency of 9 GHz. Two signals are input to the amplifier. It is observed with a spectrum analyzer that many spurious responses exist. Two spurs are measured at 9.9 GHz and 8.1 GHz. If these responses are due to ninth order effects, what are the frequencies of the two input signals?
