Abstract
A transceiver ( ) includes a synthesizer ( ) which includes a single phase locked loop ( ) for generating both a transmit offset signal and a receive second local oscillator (LO) signal for use by the transceiver. A single voltage controlled oscillator provides oscillator signals for both modes. A prescaler ( ) in the phase locked loop keeps the tuning distance of the VCO small. The resulting transceiver and radio including the transceiver has reduced parts count and current drain and is smaller in size then previous equipment with the same functionality.
