Integrated receive front-end modules for GPS and GLONASS signals measure 2.3 x 1.7 x 0.73 mm
Each of the three devices, optimized for different end platforms, offers low-power operation, exceptional protection against electrostatic discharge (ESD) and come in a 2.3 x 1.7 x 0.73 mm package size.
The BGM103xN7 modules combine the pre-filter and low noise amplifier (LNA) stages of the GNSS signal chain front-end to achieve a balance of performance improvements and space savings while reducing design time. The flexible solutions of Infineon meet key design goals, including high linearity to avoid interference of more powerful cellular signals, single-module coverage of the frequency range from 1575 to 1605 MHz, and optimized gain with very low noise for state-of-the-art sensitivity.
The BGM1033N7 is a standard solution meeting high-performance GPS/GLONASS specifications, with 14.8dB Gain and 1.65dB noise figure. The BGM1032N7 matches BGM1033N7 features with optimization to suppress LTE Band13 signals. The upper frequency of the LTE 13 band is 787 MHz, and the second harmonic of this frequency (i.e. 1574 MHz) falls into the GPS band.
The BGM1034N7 is a high-gain (17.0 dB) version for systems with high losses in the receive chain, such as personal navigation devices and digital still cameras, where the potential for jamming due to high power cellular signals is less critical.
Common features of the series include low current consumption to meet mobile device requirements (4.0 mA / 3.1 mA), >43 dBc out-of-band rejection in cellular bands and +30 dBm input compression point in cellular bands. Each of the devices also offers an 8 kV IEC ESD contact discharge specification at the RF input pin, which lets designers achieve ESD requirements with only one external component.
