CHA4102-QEG Datasheet S Band Digital Vga

Manufacturer: United Monolithic Semiconductors

Overview: CHA4102-QEG S band Digital VGA GaAs Monolithic Microwave IC in SMD leadless.

General Description

The CHA4102-QEG is a variable gain amplifier monolithic circuit, which integrates 6 bit digital attenuator and a 2 stage driver amplifier that produces 20dB gain, an output power of 23.5dBm and a dynamic attenuator range of 31.5dB.

It is designed for a wide range of applications, from military to mercial munication systems.

The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
