SAW-LESS RECEIVER WITH RF FREQUENCY TRANSLATED BPF

摘要

PURPOSE: An SAW(Surface Acoustic Wave)-less receiver having BPF(Band Pass Filter) is provided to remove off-chip components at high costs. CONSTITUTION: An RF-IF receiver section(28) includes a BPF, an LNA(Low Noise Amplifier) module, and a mixing section. The BPF connects a plurality of base band impedances to an FEM interface according to a plurality of phase-offset RF clock signals. The LNA module amplifies an inbound RF signal in order to generate an amplified inbound RF signal. The mixing section mixes the amplified inbound radio frequency signal to the local oscillation in order to be created the inbound intermediate frequency signal.
