摘要：

This paper presents a 28-GHz monolithic quadrature voltage-controlled oscillator (QVCO) realized in a preproduction 0.4-mum SiGe bipolar technology with 85-GHz transit frequency. QVCOs efficiently drive quadrature modulators and demodulators in receivers or transmitters. At 28.9 GHz, the circuit provides -14.7 dBm of output power and phase noise of -84.2 dBc/Hz at a 1-MHz offset. The two output signals are in quadrature with phase error of about 5degrees. Timing of the QVCO may be done in the frequency range from 24.8 to 28.9 GHz with nearly constant output power. The circuit consumes 25.8 mA from the 5-V voltage supply.
