Abstract
[Abstract] This paper presents the design and test results of the Qualification Model 4x4 Microwave Switch Matrix (MSM) using PIN diode switches for the Communication, Oceanographic, and Meteorological Satellite (COMS) Ka-band communication payload. The parallel capacitance of a PIN diode restricts the isolation of the series PIN diode switch and the switch driver circuit limits the switching speed of PIN diode switch. The resonant circuitry and the TTL compatible switch driver circuit are proposed to obtain high isolation and high switching speed. High path isolation in the 4x4 MSM module was accomplished by using the appropriate interconnection cavity between 4-way power divider and SPST switch. The test results of the Qualification Model 4x4 MSM show that insertion loss is 16 dB, on-off isolation is more than 57 dB and on-off transition time is below than 30 ns.
