Paper Abstract

GaAs circuits for use in a fully monolithic 1 Gb/s optical controller have been developed and tested. The circuits include photodetectors, transimpedence amplifiers and 1:16 demultiplexers that can directly control the phase of MMIC phase shifters. The entire chip contains approximately 300 self-aligned gate E/D-mode MESFETs. The MESFETs have one micron-wide gate and the E-mode FETs typically have transconductance of 200 ms/mm. Results of simulations and tests are reported. Also, the design and layout of the fully monolithic chip is discussed.
