ABSTRACT:
An RF receiver apparatus that is suitable for implementation as a monolithic IC core with minimum external components is disclosed. The receiver apparatus features low noise figure, low intermodulation and almost fixed input impedance over a broad frequency band covering cable TV, broadcast TV, direct broadcast satellite TV. Other outstanding features includes 40 dB dynamic gain controllable range and minimum electromagnetic radiation due to fully differential signal design. Above all, due to the highly integrated design of the invention, it is suitable for miniaturized tuner appliation.
