CHA7114 Datasheet X Band High Power Amplifier

Manufacturer: United Monolithic Semiconductors

Overview: CHA7114 X Band High Power Amplifier GaAs Monolithic Microwave IC Vg2.

General Description

..The Pout (dBm) & PAE (%) & Gain (dB) CHA7114 is a monolithic two-stage GaAs high power amplifier designed for X band applications.

This device is manufactured using a UMS 0.25 µm power pHEMT process, including, via holes through the substrate and air bridges.

To simplify the assembly process: • The backside of the chip is both RF and DC grounded • Bond pads and back side are gold plated for patibility with eutectic die attach method and thermo-pression bonding process.
