Abstract :
A family of fully monolithic VCOs utilizing GaInP/GaAs HBTs are presented for the first time. They operate at 14 GHz and 28 GHz with tuning bandwidths ranging from 10.7% to 19.6%. Output powers vary between -9dBm and +3 dBm with an integrated 6 dB attenuator to reduce pulling. The fabrication yield is higher than 50%. On-wafer measurements show a very small dispersion, and good agreement with the small signal simulations.<>
