About this document
Scope and purpose
This application note describes Infineon’s GNSS MMIC LNA: BGA524N6 as Low Noise Amplifer for Global
Navigation Satellite System (1550 MHz – 1615 MHz) applications.
1. This application note investigates the BGA524N6’s performance for at 1550 MHz - 1615 MHz
using a high quality factor inductor for input matching.
2. The BGA524N6 is a Silicon-Germanium Low Noise Amplifer.
3. The BGA524N6 serves the Global Navigation Satellite System applications such as GPS, GLONASS,
Galieo and Beidou.
4. In this application note, the performance parameters are measured for GNSS applications on a
FR4 board. The GNSS related Out-of-band IP3 and LTE Band 13 interference are also presented.
The high quality factor inductor brings a Noise Figure improvement of 0.05 dB as compared to the
low quality factor solution in Application Note AN346.
5. Key performance parameters achieved at 2.8V, 1575.42 MHz
a. Noise Figure = 0.73 dB
b. Gain = 19.6 dB
c. Input P1dB = -12.0 dBm
d. Input IP3 = -9.1 dBm
e. Out-of-band IP3 = -4.5 dBm
