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

.
