9 to 14 GHz power amplifiers boast on chip power detectors

Hittite Microwave Corporation has introduced two 2 W GaAs pHEMT MMIC power amplifiers which cover the 9 to 14 GHz frequency range and are ideal for microwave radio, military and space, SATCOM and test and measurement applications.

The HMC952 and the HMC952LP5GE are four stage GaAs pHEMT MMIC 2-W medium power amplifiers with temperature compensated on chip power detectors which operate between 9 and 14 GHz. These amplifiers provide 33 dB of gain, +35 dBm of saturated output power, and 27% PAE (Power Added Efficiency) from a +6 V supply.

With up to +43 dBm output IP3 the HMC952LP5GE is ideal for high linearity applications in military and space as well as high capacity point-to-point and point-to-multi-point radios. These powerful amplifiers also feature I/Os that are internally matched to 50 Ohms and require no external matching components which makes them ideal for use as drivers, or as the final power stage in a microwave transmitter chain.

The HMC952 die may be easily incorporated into MCMs, while the HMC952LP5GE leadless QFN 5 x 5 mm surface mount packaged version is compatible with high volume assembly equipment. Both amplifer versions are a much smaller alternative to bolt down power amplifier solutions, and complement Hittite’s unmatched selection of active and passive components for microwave and millimeterwave radio applications.
