Description
The AL7 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 output,
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.
