Abstract :
A monolithic 23.5 to 94 GHz frequency quadrupler based on 0.1 μm pseudomorphic AlGaAs/InGaAs/GaAs high electron mobility transistor (HEMT) technology has been developed. This frequency quadrupler consists of a 23.5 to 47 GHz doubler, a 47 to 94 GHz doubler, and a 47 GHz buffer amplifier between the two doublers. It exhibits a measured conversion loss of 5-7 dB at output frequency from 94 to 98 GHz. To our knowledge, this is the first reported W-band (75-110 GHz) monolithic frequency quadrupler using HEMT technology. It can be integrated with 23.5 GHz VCOs to construct low phase noise and stable frequency sources around 94 GHz.
