\ .I MILLIMETER-WAVE MULTIPLIERS RELY ON DIODE INTEGRATED CIRCUITS IN FINLINE STRUCTURES FOR HIGH OUTPUT POWER ARLEN DETHLEFSEN, ROLF DALICHOW, DALE ALBIN, DAVID WILSON NETWORK MEASUREMENTS DIVISION 1400 FOUNTAIN GROVE PARKWAY SANTA ROSA, CALIFORNIA 95401 RJ &. Microwave Measurement Symposium and Exhibition Flin- HEWLETT a:~ PACKARD www.HPARCHIVE.com MILLIMETER-WAVE MULTIPLIERS RELY ON DIODE INTEGRATED CIRCUITS IN FINLINE STRUCTURES FOR HIGH OUTPUT POWER This paper presents several design aspects of HP's new frequency-multiplying millimeter-wave source modules. The tradeoffs between using fundamental oscillators vs. frequency multiplying techniques are examined, followed by a discussion of various ways of realizing both frequency doublers and triplers at millimeter-wave frequencies. A diode integrated circuit, which forms the heart of both the doubler and tripler circuits by achieving very good conversion efficiency, is also described. The block diagram of the source modules and their typical performance are presented.
