CIRCUIT DESCRIPTION

General

The MC13144 is a low noise amplifier with programmable

LNA

The LNA is a unique and patented cascode amplifier with

digitally (2 bit) programmable bias (see Internal Circuit

Schematic). Typical gain of the LNA is 17 dB for minimum

noise figure of 1.4 dB at 900 MHz.

bias. This device is designated for use in the front end section

in analog and digital FM systems such as Wireless Local

Area Network (LAN), Digital European Cordless Telephone

(DECT), PHS, PCS, GPS, Cellular, UHF and 800 MHz

Special Mobile Radio (SMR), UHF Family Radio Services

and 902 to 928 MHz cordless telephones.

Programmable Bias/Enable Circuit

This unique circuit allows for 3 bias levels and a standby

mode in which the LNA can be externally biased as desired.

Current Regulation/Enable

Temperature compensating voltage independent current

regulation is digitally controlled by a 2 bit programmable

bias/enable circuit.
