LMX2331A - Dual Frequency Synthesizer

Description

The LMX233xA family of monolithic, integrated dual frequency synthesizers, including prescalers, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver.

It is fabricated using National’s ABiC IV silicon BiCMOS process.

The LMX233xA contains dual modulus prescalers.
