Custom MMIC in Chelmsford, Mass., is introducing the DC- 18 GHz SP3T and SP5T non-reflective RF and microwave gallium arsenide (GaAs) switches for military, telecommunications, and test and measurement applications. The SP3T CMD234C4 provides high isolation of 40 dB at 10 GHz and low insertion loss of 2 dB. The CMD234C4 includes an onboard binary decoder circuit, requiring 2 complementary control voltage logic lines of 0/-5 volts. The SP5T CMD235C4, similar to the SP3T design, has a low-power integrated 3:8 TTL decoder for enhanced digital control. The CMD235C4 provides low insertion loss of 2.5 dB and a high isolation of 40 dB at 10 GHz. The CMD235C4 and CMD234C4 come in small size and lead-free, RoHs-compliant 4x4 SMT QFN packages, and have a switching speed of 66 nanoseconds.
