Neubiberg, Germany: A new series of receiver front-end modules (FEMs) for implementing Global Navigation Satellite Systems (GNSS) in smartphones and handhelds offer unparalleled noise figures, according to developer Infineon. They also come in a package measuring a mere 2.3 by 1.7 by 0.73mm.
Pre-filter and low-noise-amplifier (LNA) stages of the GNSS signal-chain front-end are combined to achieve a balance of performance improvements and space savings. Other features include high linearity to avoid interference of more powerful cellular signals, single-module coverage of the frequency range from 1575 to 1605MHz, and optimised gain for sensitivity.
The modules are a pin-to-pin-compatible upgrade with the previous-generation BGM103xN7.
