71.8 GHz static frequency divider in a SiGe bipolar technology

A 2:1 static frequency divider fabricated in a 0.35 /spl mu/m SiGe bipolar technology is described. It operates up to 71.8 GHz and draws 132 mA from a single 4.5 V supply. Continuous operation up to the maximum operating frequency of 71.8 GHz has been demonstrated. This operating frequency is the highest achieved for this type of circuit in Si-based technologies and comparable with the fastest static dividers realized in III-V technologies.
