Hittite has introduced two new additions to its medium power amplifier product line. These GaAs PHEMT MMIC amplifiers provide frequency coverage in the 5 to 18 GHz and 34 to 42 GHz bands and are designed for use in a wide range of applications including point-to-point and point-to-multipoint radios, VSAT, military aerospace, fibre-optics, sensors and test instrumentation.
The HMC451LP3E is a highly efficient, medium power amplifier which operates from 5 to 18 GHz. It provides 18 dB gain and +21 dBm saturated output power at 18% PAE, while consuming only 120 mA from a +5 V supply. The device also features +28 dBm output IP3, operates from -40°C to +85°C, and is housed in a leadless RoHS compliant plastic SMT package. The HMC451LP3E provides 50 Ω matched and DC blocked I/Os and requires no external matching components, making it a suitable linear gain block or LO driver for Hittite’s range of mixer products.
The HMC-ABH264 is a high dynamic range medium power amplifier chip which operates between 34 and 42 GHz. It provides 18,5 dB of gain, a P1dB of +18 dBm and +29 dBm output IP3, while consuming only 120 mA from a single +5 V supply. The device also features 50 Ω matched and DC blocked I/Os and provides excellent gain flatness over its rated bandwidth. Specified for operation from -55°C to +85°C, this highly compact amplifier is suitable for integration into multichip modules (MCMs).
