Abstract
A medium power W-band amplifier has been designed and fabricated using a low cost production oriented PHEMT technology which is based only on optical stepper lithography. The 3-stage amplifier utilizes coplanar transmission lines which results in a compact chip size of 1x2 mm2. A gain of 10.4 dB is achieved at a frequency of 92 GHz in conjunction with 10.6 dBm output power for 3 dB gain compression.
