Description

The LA7 limiting amplifier is a discrete hybrid design, which

uses thin film manufacturing processes for accurate

performance and high reliability.

This design uses a Schottky diode limiter circuit at the input,

and a single stage bipolar transistor feedback amplifier at the

output. An RF choke is used for DC power supply decoupling

.

Both TO-8 and Surface Mount packages are hermetically

sealed, and MIL-STD-883 environmental screening is available.
