A one-by-four static frequency divider using AlGaAs/GaAs heterojunction bipolar transistors (HBTs) was designed to operate at a bias condition that gave a maximum cutoff frequency fT and a maximum oscillation freqency fmax. The fT and fmax applied to the divider were 68 GHz and 56 GHz, respectively. As a result of the tests, the circuit operated up to 34.8 GHz at a power supply voltage of 9 V and power dissipation of 495 mW. A low minimum input signal power level of 0 dBm was also achieved.
