LMX3161  
Single Chip Radio Transceiver  
vides a low cost, high performance solution for communica-  
tions systems. The RSSI output may be used for channel  
quality monitoring.  
General Description  
The LMX3161 Single Chip Radio Transceiver is a monolithic,  
integrated radio transceiver optimized for use in a Digital En-  
hanced Cordless Telecommunications (DECT) system. It is  
The Single Chip Radio Transceiver is available in a 48-pin  
7mm X 7mm X 1.4mm PQFP surface mount plastic pack-  
age.  
fabricated using National’s ABiC  
V BiCMOS process  
=
(fT 18 GHz).  
The LMX3161 contains phase locked loop (PLL), transmit  
and receive functions. The 1.1 GHz PLL block is shared be-  
tween transmit and receive section. The transmitter includes  
a frequency doubler, and a high frequency buffer. The re-  
ceiver consists of a 2.0 GHz low noise mixer, an intermediate  
frequency (IF) amplifier, a high gain limiting amplifier, a fre-  
quency discriminator, a received signal strength indicator  
(RSSI), and an analog DC compensation loop. The PLL,  
doubler, and buffers can be used to implement open loop  
modulation along with an external VCO and loop filter. The  
circuit features on-chip voltage regulation to allow supply  
voltages ranging from 3.0V to 5.5V. Two additional voltage  
regulators provide a stable supply source to external dis-  
crete stages in the Tx and Rx chains.  
Features  
n Single chip solution for DECT RF transceiver  
n RF sensitivity to −93 dBm; RSSI sensitivity to −100 dBm  
n Two regulated voltage outputs for discrete amplifiers  
n High gain (85 dB) intermediate frequency strip  
n Allows unregulated 3.0V–5.5V supply voltage  
n Power down mode for increased current savings  
n System noise figure 6.5 dB (typ)  
Applications  
n Digital Enhanced Cordless Telecommunications (DECT)  
n Personal wireless communications (PCS/PCN)  
n Wireless local area networks (WLANs)  
n Other wireless communications systems  
The IF amplifier, high gain limiting amplifier, and discrimina-  
tor are optimized for 110 MHz operation, with a total IF gain  
of 85 dB. The single conversion receiver architecture pro-
