The new modules are pin-to-pin compatible with the previous generation BGM103xN7, and therefore remain the world's smallest for this application, measuring just 2.3 x 1.7 x 0.73 mm. They support simultaneous reception of both GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System) signals. The devices are optimized for various termination platforms and offer industry-leading noise figures, low-power operation, and exceptional electrostatic discharge (ESD) protection.
For receiving weak GNSS signals, a low noise figure is achieved with a short TTFF (Time-To-First-Fix), which is the time required for a GNSS receiver to acquire satellite signals, navigation data, and calculate a position. The new BGM104xN7 series offers a 0.15dB noise figure, a better result than the BGM103xN7 series. This puts Infineon's solution ahead of all other solutions on the market by 0.5dB. This improved performance is achieved in a package that is almost 22% smaller than the second smallest device available.
Infineon's BGM104xN7 modules combine the pre-filter and low-noise amplifier (LNA) stages of the GNSS front-end signal chain to achieve a balance between performance improvements and space savings while reducing design time. The low noise figure enhances the user experience when navigating with smartphones or other handheld devices. Furthermore, the device family meets fundamental design objectives: high linearity to avoid interference from even the strongest cellular signals, single-module coverage of the 1.575 to 1.605 MHz frequency range, and optimized gain for cutting-edge sensitivity.
The new BGM104xN7 series contains two modules, geared towards specific platform applications:
BGM1043N7: Standard solution that brings together high performance in GPS / GLONASS specifications, with a gain of 14.8 dB and a noise index of 1.5 dB.
BGM1044N7: High gain version (17.0 dB) (1.55 dB noise figure) for systems with large losses in the receiving chain, such as personal navigation devices and digital cameras, where the potential for interference due to high cellular electrical signals is less critical.
