BGA123L4
Small Footprint Ultra Low Current Low Noise Amplifier for Global
Navigation Satellite Systems (GNSS)
Features
Application
BGA123L4 is designed to enhance GNSS signal sensitivity especially in wearables and mobile cellular IoT devices.
With 18.2 dB gain and only 0.75 dB noise figure it ensures high system sensitivity. The current needed is only 1.1
mA which means just 1.3 mW power consumption, which is critical to help to conserve batteries. The wide supply
voltage range of 1.1 V to 3.6 V ensures flexible design and high compatibility. It supports all GNSS systems
including GPS, GLONASS, Beidou and Galileo.
Product Validation
Qualified for industrial applications according to the relevant tests of JEDEC47/20/22.

Small Footprint Ultra Low Current Low Noise Amplifier for Global Navigation
Features
Description
The BGA123L4 is a ultra low current low noise amplifier for Global Navigation Satellite Systems (GNSS) which
covers all GNSS frequency bands from 1550 MHz to 1615 MHz like GPS, GLONASS, Beidou, Galileo and others. The
LNA provides 18.2 dB gain and 0.75 dB noise figure at a current consumption of only 1.1 mA in the application
configuration described in Chapter 4. The BGA123L4 is based upon Infineon Technologies‘ B7HF Silicon
Germanium technology. It operates from 1.1 V to 3.6 V supply voltage.
