New Power Amplifiers are Ideal for Military and Microwave Radio Applications. Two New PA Die Deliver High Gain and High Power Added Efficiency.
Chelmsford, MA, March 23, 2010 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, announces the release of two new GaAs pHEMT based power amplifier MMIC die which are ideal for automotive radar, medical, military, microwave radio, SATCOM and sensor applications from 24 to 29.5 GHz.
The HMC863 is a three stage GaAs pHEMT MMIC 1/2 Watt Power Amplifier which operates from 24 to 29.5 GHz and provides 26 dB gain and +28 dBm saturated output power at 18% power added efficiency (PAE). This high linearity amplifier also delivers high output IP3 of +38 dBm, while consuming only 375 mA from a +6 V supply. For added flexibility, the HMC863 power amplifier can also be operated from a +5 V supply, offering up to +26.5 dBm saturated output power.
Also released is the HMC864 three stage GaAs pHEMT MMIC 1 Watt Power Amplifier. This flexible power amplifier operates from 24 to 29.5 GHz with 26 dB gain, and +31 dBm of saturated output power at 18% PAE. The HMC864 consumes only 750 mA from a +6 V supply, while delivering +29 dBm output P1dB, and +40 dBm output IP3. This amplifier can also be operated from a +5 V supply, providing up to +29.5 dBm saturated output power.
The RF inputs and outputs of the HMC863 and HMC864 power amplifiers are DC blocked and matched to 50 Ohms for ease of integration into Multi-Chip-Modules (MCMs). Both amplifiers are rated for operation from -55 °C to +85 °C, and require no external matching components. The HMC863 and HMC864 power amplifier MMICs complement Hittite’s broad line of linear and power amplifier products which are offered in chip, SMT and connectorized module formats.
