Description

The A77 RF amplifier is a discrete hybrid design, which

uses thin film manufacturing processes for accurate

performance and high reliability.

The single stage bipolar transistor feedback amplifier

design displays impressive performance over a broadband

frequency range. Both TO-8 and Surface Mount packages

are hermetically sealed, and MIL-STD-883 environmental

screening is available.
