Abstract:
1. An RF receiver system comprising: a plurality of selectable antennas; a receiver comprising front end circuitry and an analog-to-digital converter coupled to the front end circuitry for receiving RF signals from one of the plurality of antennas, said receiver further comprising processing circuitry for processing the RF signals and generating a control signal comprising a binary logic signal to control selection of one of the plurality of antennas; and a switched diversity module comprising a plurality of switches coupled to said plurality of selectable antennas for selecting one of the plurality of antennas at a time, said switched diversity module further comprising logic receiving the control signal including the binary logic signal generated by the processing circuitry in the receiver and generating logic output signals to control the plurality of switches to select one of the plurality of antennas at a time, wherein said control signal causes selection of a different one of the plurality of antennas at a time when the binary logic signal transitions between two states.
