CMD203C4

DC - 20 GHz (L, S, C, X, Ku, K Band) SP4T Non-reflective Switch MMIC

Qorvo's CMD203C4 is a broadband RF / Microwave MMIC SP4T switch housed in a leadless 4x4 mm surface mount (SMT) 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 switch MMIC operates using complementary control voltage logic lines of 0/-5 V and consumes little DC current.
