Description

The A37 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

.
