Description
The L42 signal limiter is a discrete hybrid design, which uses thin film
manufacturing processes for accurate performance and high reliability.
This design uses Schottky bridge quad and anti-parallel diodes, which
provide consistent limiting levels over a broadband frequency range.
Both TO-8 and SMTO-8 packages are hermetically sealed, and
MIL-STD-883 environmental screening is available
.
