CMD203

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

Qorvo's CMD203 is a broadband RF / Microwave MMIC SP4T switch in die form. The CMD203 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 CMD203 switch MMIC operates using complementary control voltage logic lines of 0/-5 V and consumes little DC current.
