Description

The A77-1 RF amplifier is a discrete hybrid

design, which incorporates the use of thin film

manufacturing processes for accurate performance

and high reliability. The single stage silicon 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 hermeti-

cally sealed, and MIL-STD-883 environmental

screening is available.
