27 GHz monolithically integrated VCO with frequency divider in SiGe bipolar technology

This paper presents a monolithic voltage-controlled oscillator with static frequency divider in a pre-production 0.4 /spl mu/m SiGe bipolar technology for broadband communication applications. The voltage-controlled oscillator operates from 21 GHz to 27 GHz. The division ratio of the static frequency divider is 16. The circuit consumes 500 mW from the 5 V supply including the two output buffers.
