L42 Datasheet, PDF (1/3 Pages) Tyco Electronics – Thin Film Limiter Module 50 to 4000 MHz

L42 / SML42
Thin Film Limiter Module
50 to 4000 MHz
Features
• VERY WIDE BANDWIDTH
• GOOD SUPPRESSION OF EVEN ORDER HARMONICS
• LOW INSERTION LOSS: 3.5 dB (TYP.)
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.
