Description
The A80 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance
and high reliability.
The 2 stage silicon bipolar feedback amplifier design displays
impressive performance over a broadband frequency range.
An isolation transformer is used in the feedback loop, with the
benefit of high reverse isolation.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available
.
