Hittite Microwave Corp. has unveiled chip and surface-mount GaAs pHEMT power amplifiers for a wide range of applications from DC to 6 GHz. The chip amplifier, model HMC637, provides 14-dB gain with +30-dBm saturated output power and +41-dBm third-order intercept point from DC to 6 GHz. The chip amplifier does not require matching external components and consumes only 400 mA current from a +12-VDC supply.

The surface-mount amplifier, model HMC637LP5, provides performance similar to the chip, but is supplied in a RoHS-compliant 5 x 5 mm leadless QFN surface-mount package. Like the chip amplifier, it is suitable for applications in military electronic warfare (EW) and electronic countermeasures (ECM), test and measurement equipment, and telecommunications systems.
