Highly integrated 1.9 GHz low-IF CMOS transceiver.
Down conversion to half the DECT channel spacing (864 kHz).
On-chip channel select filter.
On-chip Voltage Controlled Oscillator (VCO).
On-chip low noise amplifier (LNA).
Open-loop modulation.
On-chip timing control.
Four digital (5 mA) output ports.
0 dBm PA driver output.
-95 dBm sensitivity.
2.5V operation.
Small 44 pin Leadless Leadframe Package 3.0.

LMX4168 Radio Transceiver for DECT ADVANCED INFORMATION March 2004 LMX4168 Radio Transceiver for DECT 1.0 General description The LMX4168 is a radio transceiver integrated circuit optimized for the Digital Enhanced Cordless Telecommunications (DECT) system. The transceiver, when combined with a power amplifier and a Tx/Rx switch, implements a complete DECT radio transceiver compliant with the ETSI CTR6 standard. The LMX4168 interfaces to National Semiconductor’s SC144XX DECT family of baseband processors. The LMX4168 integrates a complete transmitter, consisting of a phase locked loop, VCO and PA driver. The receiver contains LNA, quadrature downconverter, polyphase filter/combiner, automatic gain control, and demodulator. The LMX4168 operates from a single 2.25–2.75V supply.
