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.
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.
