CMD203C4 DC-20 GHz SP4T Non-reflective Switch Product Overview The CMD203C4 is a broadband MMIC SP4T switch housed in a leadless 4x4 mm surface mount package. The CMD203C4 covers DC to 20 GHz and offers a low insertion loss of 2.4 dB and high isolation of 39 dB at 10 GHz. The switch also includes an on board binary decoder circuit which reduces the number of required logic control lines from four to two. The CMD203C4 operates using complementary control voltage logic lines of 0/-5 V and consumes little DC current.
