HMC789ST89E SMT MMIC Driver Amplifier

January 17, 2011

New HBT Driver Amplifier for Cellular/3G and WiMAX/4G Applications Delivers up to +27 dBm Output Psat from 700 MHz to 2.8 GHz.

Chelmsford, MA, July 17, 2009 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a new SMT MMIC Driver Amplifier which is ideal for high linearity applications in Cellular/3G, WiMAX/4G, and fixed wireless equipment applications from 700 MHz to 2.8 GHz.

The HMC789ST89E is a GaAs InGaP HBT Driver Amplifier MMIC which is rated from 700 MHz to 2.8 GHz. Simple external matching allows the HMC789ST89E to deliver up to 18 dB gain, +25 dBm output P1dB, and up to +45 dBm output IP3 in selected 3G/4G frequency bands. The active on-chip bias circuit allows the HMC789ST89E to exhibit excellent gain and output power stability over temperature, and to provide up to 45% power added efficiency (PAE) under high incident power levels. The high output IP3, high gain, and low quiescent current make the HMC789ST89E ideal for use in PA driver & pre-driver applications in Cellular/3G, WiMAX/4G and fixed wireless transceivers.

The HMC789ST89E is packaged in an industry standard RoHS compliant SOT-89 package and consumes only 125 mA from a single +5V supply.
