Abstract
A receiver (400) includes a tracking bandpass filter (420) and a signal processing circuit (430-480). The tracking bandpass filter (420) has a first input for receiving a radio frequency (RF) signal, and an output, and includes a first portion (731) on a semiconductor die (730), and at least one inductor (721). The at least one inductor (721) is operatively coupled to the first portion of the tracking bandpass filter (420). The signal processing circuit (430-480) has an input coupled to the output of the tracking bandpass filter (420), and an output for providing a processed signal. The semiconductor die (730) and the at least one inductor (721) are integrated into a single multi-chip module (MCM) (710).
