2W & 5W Power Amplifiers with On Chip Power Detectors Cover 9 to14 GHz!

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has launched three new 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 & measurement applications.

The HMC952 and the HMC952LP5GE are four stage GaAs pHEMT MMIC 2 Watt 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 +6V 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. 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 amplifier 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.

The HMC1053 is a four stage GaAs pHEMT MMIC 5 Watt Power Amplifier with Power Detector which operates between 9 and 14 GHz. The HMC1053 provides 34 dB of gain, +43 dBm output IP3 and +38 dBm of saturated output power at 26% PAE from a +7V power supply. The HMC1053 exhibits excellent linearity and is optimized for high capacity point-to-point and point-to-multi-point radio systems.

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.
