hi,
I have designed a mixer which has -1.477dBm 1dB compression point,but for the same I am unable to simulate the IIP3, RF frequncy is 2.4GHz and LO is 2.3GHz for this
mixer...please help......
Use 2 sine waves @ F1 & F2 with -10dBm and do harmonic balance simulations in spectre. Get F1-F2 amplitude subtract 10dBm (F1 amplitude) and you will get IIP3. Theoretically it should be ~10dB less than P1dB
