Hi! everybody
I'm simulating a 4th harmonic mixer with an anti-parallel diode pair, LO=8.5GHz;RF=34-36GHz;IF=DC-2GHz.
When i simulate it as down-converter,the conversion loss is about 8 to 10dB,but when use it as up-converter,the conversion loss changes to 2 to 4dB.
but i think the conversion loss should be the same whether use it as up-converter or down-converter.I was puzzled.Is my rusult natural? or there is some thing wrong with my design or simulating method.
Thank u for helping me!
