Hittite Microwave Corp. has released its model HMC641 GaAs pseudomorphic-high-electron-mobility-transistor (pHEMT) single-pole, four-throw (SP4T) switch for a wide range of applications from DC to 18 GHz. The non-reflective, SP4T monolithic-microwave-integrated-circuit (MMIC) chip measures just 1.9 x 1.6 mm with 2 dB insertion loss and 42 dB isolation at midband frequencies. It features an on-chip binary decoder that requires only two control lines.

The tiny MMIC chip switch is ideal for military radios, test equipment, space communications, and industrial systems requiring broadband performance. It achieves a third-order intercept point of +40 dBm with a 1-dB output-power compression point of +24 dBm. It requires no external matching components and uses control voltages of 0 and -5 VDC, drawing only 3 mA current from a fixed -5 VDC supply. The company offers a wide range of switch products in die and packaged formats for applications through 86 GHz.
