A High IP3 RF Receiver Chip Set for Mobile Radio Base Stations up to 2 GHz

摘要

We present a monolithically integrated high IP3 RF receiver chip set for mobile radio base stations up to 2 GHz, in a 25 GHz f_T Si bipolar production technology. The chip set consists of a RF preamplifier, an active mixer and an IF limiter. The preamplifier gain is 12 dB, the noise figure is 5.5 dB and the IP3_(OUT) is +24 dBm at 900 MHz. The mixer conversion gain is 1.5 dB, the IP3_(OUT) is +26 dBm and the SSB noise figure is 16.5 dB. The limiter provides a high overload protection and a high bandwidth.
