World’s smallest integrated receive front-end modules focus on GPS and GLONASS applications

The new BGM103xN7 Series devices are the first modules available that support separate or simultaneous reception of both Global Positioning System (GPS) and Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) signals. Each of the three devices, optimized for different end platforms, offers low-power operation and protection against electrostatic discharge (ESD) and tiny package size (2.3 x 1.7 x 0.73 mm).

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 low noise for state-of-the-art sensitivity.

The three modules in the new BGM series, targeted for specific platform applications, are:

  • BGM1033N7: Standard solution meeting high-performance GPS/GLONASS specifications, with 14.8 dB Gain and 1.65 dB noise figure.
  • 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.
  • BGM1034N7: 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.

To meet diverse design requirements, the Infineon BGM103xN47 modules give engineers the flexibility to place any necessary post-filter (single-ended/balanced with suitable NF and attenuation) close to the GNSS receiver, while placing the pre-filter and LNA close to the antenna to achieve optimized sensitivity. Each of the modules feature a low insertion loss / high out-of-band rejection pre-filter followed by a high performance GNSS LNA.

Availability and Pricing 

Modules are now available. Infineon also provides evaluation kits.

Typical pricing for BGM103xN7 modules is €0.35/$0.50 (10,000 piece volume). The devices are shipped in a TSNP-7-10 leadless package (2.3 mm x 1.7 mm x 0.73 mm) which makes them the smallest available solutions in the market.
