The MC13144 is designed in the Motorola High Frequency Bipolar
MOSIAC V wafer process to provide excellent performance in analog and
digital communication systems. It includes a cascoded LNA usable up to

2.0 GHz and at 1.8 Vdc, with 2 bit digital programming of the LNA bias.
Targeted applications are in the UHF Family Radio Services, UHF and
800 MHz Special Mobile Radio, 800 MHz Cellular and GSM, PCS, DECT
and PHS at 1.8 to 2.0 GHz and Cordless Telephones in the 902 to 928 MHz
band covered by FCC Title 47; Part 15. The MC13144 offers the following
features:

• 17 dB Gain at 900 MHz

• 1.4 dB Noise Figure at 900 MHz

• 1.0 dB Compression Point of –7.0 dBm; Input Third Order Intercept

Point of –5.0 dBm

• Low Operating Supply Voltage (1.8 to 6.0 Vdc)

• Programmable Bias with Enable 1 and Enable 2

• Enable 1 and Enable 2 Programmed High for Optimal Noise Figure and

Gain Associated with NF

• Can Override Enable and Externally Program In Up to 15 mA

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.

Figure 1. MC13144 Internal 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.
