It is the smallest module available, Infineon believes, and features very high linearity, lowest noise figure and it supports all navigation standards including GPS, GLONASS and BeiDou. With a footprint of 1.5 x 1.1 mm BGM1143N9 requires 60% less board space compared to the previous generation. In a phone, transmitter and receiver have to work together simultaneously without degrading each other’s performance. A GNSS receiver co-exists with transceivers in the GSM/ EDGE/ UMTS/ LTE bands that transmit high power in the range of +24 dBm. 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.
The BGM1143N9 improves sensitivity compared to other solutions available in the market today. 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).
