Abstract :
We report on the design and measurement of a broadband MIC balanced varactor frequency doubler. The design can be easily scaled to millimeter-wave frequencies using a monolithic approach. The design incorporates a novel balun to achieve a grounded-CPW to slotline transition. The balanced structure offers inherent isolation in the output port from all odd harmonics including the fundamental frequency. Measurements show a port-to-port conversion loss between 8 and 10 dB over an output frequency range of 6-10 GHz.<>
