Abstract :
A GPS receiver that can coexist with cellular transceivers is implemented in a 0.18mum SiGe BiCMOS technology and occupies 3.24mm 2. The device integrates polyphase filters, VGA, ADCs, fractional-N synthesizer, LNA, and mixers, minimizing desensitization and reciprocal mixing. The receiver consumes 20mW from a 1.8V supply and has 1dB gain desensitization with a -8dBm 1.9GHz blocker
