A highly integrated Ka‐band transceiver module with two channels

A compact Ka‐band square‐wave modulation transceiver module with two receiving and transmitting channels is presented.This module consists of 15 monolithic microwave integrated circuits, two dielectric resonator oscillators, a E‐plane waveguide filter, a coupler, two power dividers, and over 200 components, and works at two Ka‐band operating frequency points. The developed Ka‐band transceiver module is fabricated using advanced packages techniques, which has a compact size of 120 mm × 60 mm × 20 mm and exhibits greater than 500 mw output power with amplitude imbalance of two output ports less than 30 mw, switch rise time and fall time less than 4 ns, isolation of transmitting two channels more than 63 dB, and voltage standing wave ratio of receiving ports better than 1.3. © 2010 Wiley Periodicals, Inc.
