LMX2411 - National Semiconductor

LMX2411 Baseband Processor

The LMX2411 is a monolithic integrated baseband processor suitable for use in Digital European Cordless Telecommunications (DECT) systems as well as other mobile telephony and wireless communications applications It is fabricated using National’s ABiC IV BiCMOS process (fT e 15 GHz) The LMX2411 contains both transmit and receive functions The transmitter uti.

Features

very low current consumption of 2 5 mA transmit and 5 mA receive (steady state) It also has separate power down pins for transmit and receive functions to further reduce power consumption The LMX2411 can be used with the LMX2216B LNA Mixer the LMX2240 IF Receiver and the LMX2320 Phase-Locked Loop to form a complete RF front end solution These chips form the major blocks of an RF front end solution for DECT The LMX2411 is available in a 16-pin JEDEC surface mount plastic package Features Y Y Y Y Y Y Y Y High speed voltage comparator (40 ns settling time) Generates Gaussian filtered modulat.
