Infineon GNSS module boosts smartphone navigation function

Infineon Technologies showcased its BGM1143N9 pico global navigation satellite system module at the European Microwave Week trade show. Reportedly the smallest GNSS module to date, BGM1143N9 combines Infineon's high-performance low noise amplifier with a low-insertion-loss pre-filter.

The 1.5mm x 1.1mm product is available in TSNP-9 packaging and supports GPS, China's BeiDou Navigation Satellite System and other navigation standards. Infineon has released samples and evaluation boards of BGM1143N9 and intends to start mass production early next year.

BGM1143N9 requires 60 per cent less board space compared to the previous generation of GNSS modules, making it ideal for smartphones. A GNSS receiver co-exists with transceivers in the GSM/ EDGE/ UMTS/ LTE bands that transmit high power in the range of +24dBm.

Due to its very high linearity, the LNA integrated in BGM1143N9 effectively prevents interference from higher order harmonics and intermodulation products of the strong signal present in smartphones, thus ensuring reliable navigation.

It features the lowest noise figure available in the market (1.45 dB), which increases the GNSS system's sensitivity and improves time-to-first-fix (TTFF) and time-to-subsequent-fix (TTSF). This feature results in a much faster and continuous navigation and consequently much higher end user satisfaction.
