Lexor Gaussian Filters 0.17 to 15MHz - Type VG2A DIL 14 pin 0.6"

Basic Specification

A range of D.I.L. packaged passive L.C. filters with a slow roll -off Gaussian response and maximally flat delay. Applications include:-Pulse shaping, e.g. a pulse with a width equal to the rise-time of the filter will be transformed to a Gaussian, bell-shaped curve. A signal with a fast leading edge can be shaped to conform with CCIR specifications, (250nS + 5OnS) Spurious spiky signals may be filtered out of a signal path while preserving phase relationships.

Preferred impedances are 75 and 510 W.

A 16 pin Version, Type VG6A. . . is also available.
