Neubiberg, Germany: The three devices in Infineon’s BGM103xN7 series are the first receive front-end modules to support separate or simultaneous reception of both GPS and GLONASS signals in cell phones. Optimised for different end platforms, each of these devices offers low-power operation and protects against electrostatic discharge (ESD) in a 2.3- by 1.7- by 0.73-mm package (see the figure).
The 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. They feature high linearity to avoid the interference of more powerful cellular signals. Also, they provide single-module coverage of the frequency range from 1575 to 1605 MHz and optimised gain with very low noise for state-of-the-art sensitivity.
Other features include low current consumption to meet mobile device requirements (4.0/3.1 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.
