LMX4268 Description
The LMX4268 is a radio transceiver integrated circuit optimized for the Digital Cordless Telemunications (DCT) system. The transceiver, when bined with a power amplifier and a Tx/Rx switch, implements a plete 2.4GHz ISM band digital radio transceiver pliant with the FCC rules part 15. The LMX4268 interfaces directly to National Semiconductor’s SC144XX DCT family of baseband processors.
