Abstract : A gain of 20 db and an instantaneous bandwidth of 50 MHz was achieved at 70 GHz from a balanced two-port amplifier. The performance of diffused type epitaxial gallium arsenide diodes has been proven superior to that of surface barrier type diodes for millimater wave parametric amplifiers. This is particularly true when each varactor is pumped into the positive bias region. The varactor diode development effort is proceeding on schedule and sample gold plated diffused diodes will be available for tests at 70 GHz and 94 GHz shortly.
