MOTOROLA ANALOG IC DEVICE DATA
CIRCUIT DESCRIPTION
General
The MC13144 is a low noise amplifier with programmable
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.
Current Regulation/Enable
Temperature compensating voltage independent current
regulation is digitally controlled by a 2 bit programmable
bias/enable circuit.
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.
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.
