BGA123L4
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.
