- Abstract
- This paper presents the design and test results of a high isolation and high speed 4x4 Microwave Switch Matrix (MSM) using PIN diode switches for the Communication, Oceanographic, and Meteorological Satellite (COMS) Ka-band communication payload. The resonant circuit was proposed to achieve high isolation of the switch. 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 TTL compatible switch driver circuit was designed to obtain high switching speed. The test results 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.
