LMX3160 Single Chip Radio Transceiver

General Description

The Single Chip Radio Transceiver is a monolithic, integrat-

ed radio transceiver optimized for use in the Digital Europe-

an Cordless Telecommunications (DECT) system as well as

other mobile telephony and wireless communications appli-

cations. It is fabricated using National’s ABiC V BiCMOS

for communications systems. The RSSI output can 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.

process (f

18 GHz).

The Single Chip Radio Transceiver contains both transmit

and receive functions. The transmitter includes a 1.1 GHz

phase locked loop (PLL), a frequency doubler, and a high

frequency buffer. The receiver consists of a 2.0 GHz low

noise mixer, an intermediate frequency (IF) amplifier, a high

gain limiting amplifier, a frequency discriminator, a received

signal strength indicator (RSSI), and an analog DC compen-

sation loop. The PLL, doubler, and buffers can be used to

implement open loop modulation. The circuit features an on-

board voltage regulator to allow wide supply voltages. In

addition, the on board voltage regulator has two outputs for

regulated discrete stages in the Rx and Tx chain.

Features

Single chip solution for DECT RF transceiver

RF sensitivity to

93 dBm; RSSI sensitivity to

Two regulated voltage outputs for discrete amplifier

100 dBm

High gain (85 dB) intermediate frequency strip

Allows unregulated 3.0V–5.5V supply voltage range

Power down mode for increased current savings

System noise figure 5.4 dB (typ)

Applications

The IF amplifier, high gain limiting amplifier, and discrimina-

tor operate in the 40 to 150 MHz frequency range, and the

total IF gain is 85 dB. The use of the limiter and the discrimi-

nator provides a low cost, high performance demodulator
