Description

The A231 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

.
