Application-oriented 33 GHz E/D-PMODFET static prescaler fabricated using optical lithography

We report the 33 GHz operation of a packaged divide-by-32/64 static prescaler designed for instrument applications. The technology uses 0.1-/spl mu/m enhancement- and depletion-mode (E/D) MODFET's with pseudomorphic InGaAs channels (on GaAs substrate) defined by optical lithography and a self-limiting oxide spacer technique.<
