CHA7114
X Band High Power Amplifier
GaAs Monolithic Microwave IC
Description
www.DataSheet4U.comThe 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 compatibility with eutectic die
attach method and thermo-compression
bonding process.
