A SiGe BiCMOS 5.5-6.4 GHz frequency synthesizer is presented. The synthesizer consists of an oscillator with a phase noise of -110 dBc/Hz at 1 MHz offset, and a 10 GHz phase-lock-loop circuit with an in-band phase noise of -79 dBc/Hz. The power consumption of the ICs was 9 mW and 17 mW, respectively.
