Broadband microwave frequency doublers
Abstract
The paper describes the design and the performance of a frequency doubler, realized in hybrid m.i.c. (microwave IC) technique, which generates microwave power over the whole of K-band (18-26 GHz). The conversion efficiency is approximately 10% for input power levels from 5 to 50 mW. Limiting effects occur at levels above 50 mW and depend on the frequency. Also described is a design concept for frequency doublers and mixers which is also based on a planar balun configuration but employs four instead of two diodes. This enables increase of the input power without decreasing the conversion efficiency.
