An IF-strip with integrated 2nd IF filter for a triple conversion GPS receiver

An IF-strip for a low power, triple conversion GPS receiver has been designed in a 1.0µm BiCMOS technology. The IC comprises a 179MHz 1st IF amplifier and mixer, a 4.7MHz 2nd IF with on chip RC active filter and some base-band support circuitry. A total gain of 84.7dB and a noise figure of 8.8dB have been achieved, with a current consumption of about 1.8mA.
