A monolithic optoelectronic receiver consisting of an MSM photodiode a
nd a two-stage amplifier has been fabricated using an enhancement/depl
etion 0.3 mum recessed-gate AlGaAs/GaAs HEMT process. The bandwidth of
14.3 GHz implies suitability for transmission rates of up to 20 Gbit/
s. The transimpedance is 670 OMEGA (into 50 OMEGA) and the projected s
ensitivity is -16.4 dBm (BER = 10(-9)).
