Description
The A531 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
.
