Description

The A28 RF amplifier is a discrete thin film hybrid design, which

incorporates the use of 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. An active DC biasing network is used for temperature-

stable performance, in addition to an RF Choke, used for power

supply decoupling.

Both TO-8 and Surface Mount packages are hermetically sealed,

and MIL-STD-883 environmental screening is available

.
