Infineon Technologies has introduced a new series of receive front-end modules for implementation of Global Navigation Satellite System (GNSS) functionality. The new BGM104xN7 products feature very low noise figure, which is a critical parameter for the performance of a GNSS receiver.
The 2,3 x 1,7 x 0,73 mm devices support simultaneous reception of both GPS and GLONASS signals. They are optimised for different end platforms and offer low-power operation and enhanced protection against electrostatic discharge (ESD).
The BGM104xN7 modules combine the pre-filter and low noise amplifier (LNA) stages of the GNSS signal chain front-end. They feature high linearity to avoid interference of more powerful cellular signals, single-module coverage of the frequency range from 1575 to 1605 MHz, and optimised gain for high sensitivity.
The BGM1043N7 is a standard solution meeting high-performance GPS/GLONASS specifications, with 14,8 dB gain and 1,5 dB noise figure. The BGM1044N7 is a high-gain (17,0 dB) version (1,55 dB noise figure) for systems with high losses in the receive chain, where the potential for jamming due to high-power cellular signals is less critical.
