thanks for ur reply.
all the test and measurement, including certification standard, i fully understand.
what i am interested, is that I can simulate these parameter in system design.
for example, I can simulate the "intermodulation rejection" of this type of 2-downconverter FM receiver in agilent ADS system design.
to emulate which component have more cricital effect in system, LNA, mixer or filter?
can anyone give me such example or suggestion to me in simulation in ADS.
my project is oooooooooooold FM receiver. I cannot find examples in ADS example, where too many of modern communication, GSM, CDMA...
