New DC-26GHz SPDT MMIC switch offers low insertion loss and high isolation

A new SPDT switch has been introduced by Custom MMIC. The CMD230 offers a 1.4dB insertion loss - the company’s lowest yet for an SPDT. The CMD230 is a general-purpose, broadband, high-isolation reflective MMIC SPDT switch in die form. Covering DC to 26GHz, it features low insertion loss of 1.4dB, Input IP3 of 37dBm and high isolation of 40dB at 13GHz. The CMD230 operates using complementary control voltage logic lines of 0/-5V and requires no bias supply. The CMD230 switch is pin-compatible with the now obsolete CSW0118 from Celeritek. Applications include microwave radio, test instrumentation and defence.
