Description
The LA45 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 two-stage GaAs FET feedback amplifier at the output.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available.
