High Data-Rate Solid-State Millimeter-Wave Transmitter Module

This paper describes a solid-state millimeter-wave transmitter module consisting of an IMPATT oscillator, p-i-n quadri-phase modulator, and a three-stage IMPATT amplifier. The module has been operated up to 4-Gbits/s modulation rate with 500-mW output power in the 60-GHz range.
