Title: Digital satellite receiver and method for switching among multiple receiver antennas using diversity circuitry

Abstract: A receiver for receiving and processing digital satellite radio signals includes multiple antenna modules for receiving digital satellite radio signals, multiple processing circuits for converting digital satellite radio signals to low-IF or 0-IF signals, diversity circuitry for selecting from among multiple low-IF or 0-IF signals, and additional processing circuitry for extracting audio and/or data from the selected signals. The system also includes automatic and manual switches for selecting from among multiple antennas, and for reducing power consumption of antenna and processing circuitry.
