Abstract :
A high-performance integrated power module using U-band MMIC MESFET power amplifiers in conjunction with W-band MMIC high efficiency varactor doublers has been developed for millimeter-wave system applications. The authors present the design, fabrication, and performance of this W-band integrated power module. Measurement results show an output power of 90 mW with an overall associated gain of 29.5 dB at 94 GHz. A saturated power of over 95 mW was also achieved. These results represent the highest reported power and gain at W-band using MESFET and varactor frequency-doubling technologies. This integrated power module is suitable for future 94-GHz missile seeker applications
