DC to 85GHz TWA and Ka-band 4.9W Power Amplifier Using an Optical Lithography Based Low Cost PHEMT Process

An optical photo lithography based 0.15μm GaAs PHEMT process and 2mil-substrate technology that enables high production throughput and low cost is described.
An optical photo lithography based 0.15μm GaAs PHEMT process and 2mil-substrate technology that enables high production throughput and low cost is described. The developed process achieved Imax=575mA/mm, BVgd=14V, and 753mW/mm of output power density at P-1 condition at 18GHz. Design and test results for DC to 85GHz traveling wave...

GaAs in Space

The use of Microwave frequencies enables high gain antennas to beam the signal back to base where even more powerful ground based antennas reject cosmic noise and background noise generated by the Earth itself.
Satellites are regularly launched into Earth orbit to provide TV signals, communications services, geographic location services or to scan the planet for geological data. Some are sent to investigate neighboring planets, which just like those on timeless missions into remote corners of our solar system send data about their...

Generating Advanced Radar Signals

Radar signal generation and processing techniques are growing ever more advanced. These advances are being driven by the need to improve resolution (the ability to detect targets that are very close together) and reduce radar spectrum occupancy.
Radar signal generation and processing techniques are growing ever more advanced. These advances are being driven by the need to improve resolution (the ability to detect targets that are very close together) and reduce radar spectrum occupancy. Reducing spectral occupancy can serve two goals: reduce interference and minimize the...
