Dear all,
I want to design a LNA with spec. as following. Please give me some
advice about which type of LNA should I choose. Of course, other advice are
all welcome. Thanks ahead.
freq: 800M~950M
gain: 15db
NF: <4db
power: as less as possible
IIP3: 5dbm
process: CMOS TSMC0.18u
Main spec. above.
Could anyone give me some design example?

Best wishes
Jason

with common source structure?
