Abstract:
1. A radio frequency (RF) transceiver of the type having at least one radio frequency integrated chip (RFIC), a reference oscillator and a phase-locked oscillator, characterized in that said reference oscillator comprises a first resonator structure wherein said first resonator structure is a first film bulk acoustic resonator (FBAR) structure and said phase-locked oscillator comprises a second resonator structure wherein said second resonator structure is a second film bulk acoustic resonator (FBAR) structure further characterized in that said second resonator structure comprises a low Q based UHFVCO and said first resonator structure is a first film bulk acoustic resonator (FBAR) structure monolithically integrated with a first radio frequency integrated chip (RFIC) to define a high frequency (>3 gigahertz) reference oscillator frequency functionality.
