CT2-RX/TX IC

Description

The IC for digital cordless telephone application is AMDs CT2 PhoX controller AM 79C4xx a complete

fabricated using TEMIC’s most advanced UHF process. CT2 IC kit is available.

It covers the CT2 band (864 MHz to 868 MHz) as well as

the CT2 Plus band (up to 952 MHz). The RX/TX circuit

Electrostatic sensitive device.

provides the down conversion to the data stream and the
