3-watt Q-band waveguide PHEMT MMIC power amplifier module

3-watt Q-band waveguide PHEMT MMIC power amplifier module

Presented is a 3 watt Q-band PHEMT MMIC power amplifier module with a peak efficiency of 25% at 44.5 GHz, believed to be the highest reported at this power level and frequency. The waveguide power amplifier module features the use of thinned 2-mil GaAs MMICs with off-chip output matching and combini...

Description
Summary:Presented is a 3 watt Q-band PHEMT MMIC power amplifier module with a peak efficiency of 25% at 44.5 GHz, believed to be the highest reported at this power level and frequency. The waveguide power amplifier module features the use of thinned 2-mil GaAs MMICs with off-chip output matching and combining on a 5-mil alumina substrate.
