25 GHz Monolithic Oscillator 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 \u00b5m SiGe bipolar technology for broadband communication applications. The voltage-controlled oscillator operates from 17.8 GHz to 25 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 bu\ufb00ers."
