STMicroelectronics’ BPF8089-01SC6 RF front-end for Global Navigation Satellite System (GNSS) receivers simplifies design and saves real-estate by integrating the impedance-matching and electrostatic-discharge (ESD) protection circuitry typically implemented using discrete components.
The BPF8089-01SC6 provides a 50Ω matched interface between the receiver’s antenna and low-noise amplifier (LNA), and is ready to plug-and-play with ST’s STA8089 and STA8090 LNAs. This compact, integrated device typically replaces a matching network containing up to five capacitors, resistors, and inductors, as well as two discrete protection devices, resulting in a much smaller footprint. Designers can also leverage PCB-track specifications provided in the device datasheet to ease design challenges and ensure optimal performance.
The BPF8089-01SC6 is suitable for use in portable satellite receivers for GPS, Galileo, GLONASS, BeiDou, and QZSS constellations, which may be used in a number of applications (more info).
