LMX2240 Intermediate Frequency Receiver
April 1995
LMX2240
Intermediate Frequency Receiver
General Description
The LMX2240 is a monolithic integrated intermediate fre-
quency receiver suitable for use in Digital European Cord-
less Telecommunications (DECT) systems as well as other
mobile telephony and wireless communications applica-
tions It is fabricated using National鈥檚 ABiC
TM
IV BiCMOS
process (f
T
e
15 GHz)
The LMX2240 consists of a high gain limiting amplifier a
frequency discriminator and a received signal strength indi-
cator (RSSI) The high gain limiting amplifier and discrimina-
tor operate in the 40 MHz to 150 MHz frequency range and
the limiter has approximately 70 dB of gain The use of the
limiter and the discriminator provides a low cost high per-
formance demodulator for communications systems The
RSSI output can be used for channel quality monitoring
The LMX2240 is intended to support single conversion re-
ceivers This device saves power size and cost by eliminat-
ing the second local oscillator (LO) second converter (mix-
er) and additional filters The LMX2240 is recommended for
systems with channel bandwidths of 300 kHz to 2 5 MHz
The LMX2240 is available in a 16-pin JEDEC surface mount
plastic package
