Hittite Microwave has introduced a GaAs MMIC analogue phase shifter suitable for phased array, industrial sensors and clock and local oscillator synchronisation applications in fibre optic, military, test equipment and industrial and medical equipment and for antenna beam-shaping, anti-jamming and signal cancellation circuits. The HMC934LP5E has an analogue control voltage from 0 to 13V, and provides a continuously variable relative phase shift of up to 400° from 1- to 2GHz. It exhibits an insertion loss of 3.5dB, which is consistent versus phase shift setting and input frequency. The insertion phase of the phase shifter is monotonic with respect to control voltage and offers a typical phase flatness of +3.5/-2° versus input frequency. The phase shifter is housed in an RoHS-compliant 5x5mm QFN SMT plastic package.
