Abstract
A wideband phase-lock loop frequency synthesizer (200) used in a radio transceiver capable of being reconfigured to operate in either a transmit, receive, or battery save mode. The wideband phase-lock loop frequency synthesizer (200) includes, a divide-by-two divider (205), quadrature detector (204), offset VCO (209) and offset mixer (207) for generating a quadrature phase modulated signal. Moreover, a programmable filter (211) is used for removing predetermined harmonic components of the offset mixed signal enabling the synthesizer to operate over a wide frequency range.
