Abstract :
Microwave and RF frequency multipliers are widely used in a large number of communications, radar, civilian and military systems. This paper presents the development of active doublers operating in the S and C frequency bands. These devices are unique in that HEMTs are employed with specialized embedding networks to provide optimized performance. Conversion gains of approximately 7 dB have been attained for narrowband designs (5% bandwidth), 5 dB for medium bandwidth designs (15%), and 4 dB for wide bandwidth designs (35%). The fundamental and third harmonic rejection is approximately 40 dBc for the narrowband designs and greater than 50 dBc for the medium and wideband designs
