Description

The A21-1 RF amplifier is a discrete hybrid design, which uses

thin film manufacturing processes for accurate performance and

high reliability.

This 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

.
