Wideband mm-wave mixers for EW applications
Abstract
Requirements for millimeter-wave surveillance receivers have increased in parallel with the development of millimeter-wave radar weapon and communication systems. In order to meet these requirements, mixers with broadband coverage must be developed. A description is presented of the design and development of broadband millimeter-wave mixers suitable for the considered applications. Attention is given to diode characteristics, circuit design considerations, and performance measurements over waveguide bandwidths. The mixer design presented yields wide instantaneous band coverage at the RF port, with selective band constraints applied to the local oscillator and input port. The IF output is band limited via low-pass and band-pass diplexing at the local oscillator/mixer diode junction. The mixer design takes advantage of low-cost printed circuit fabrication technology.
