What are the major specifications i should consider before started design of a RF front end?
My requirement is 1. 30dB gain from Lnas at 14.5GHz ( so i am planning for three stage!)
2.a single balanced mixer(schottky diode based) operating on RF ~ 14.5GHzfor first down conversion and a IF filter ( at 532 MHz)cascaded together.
3. Lo section at 13.968GHz to driver the Lo port of the mixer.LO port consists of doubler with a driver amplifier and the output generated frequency is 13.968GHz

We talk about receiver, so:
1. NF/Sensitivity
2. Selectivity, Co-channel rejection, Blocking
3. Probably flatness too
Others:
OIP3, or IIP3
O-P1dB, or I-P1dB
filters,
Maybe Phase flatness,
Temperaturemance, etc.
