LMX3161
Single Chip Radio Transceiver
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
fabricated using National’s ABiC V BiCMOS process
(f
T
= 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.
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-
vides a low cost, high performance solution for communica-
tions systems. The RSSI output may be used for channel
quality monitoring.
The Single Chip Radio Transceiver is available in a 48-pin
7mm X 7mm X 1.4mm PQFP surface mount plastic pack-
age.
