STMicroelectronics BPF8089-01SC6 RF front-end IC for GNSS receivers

Click2Contact

STMicroelectronics’ BPF8089-01SC6 RF front-end IC 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 product 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. The 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 small footprint. Designers can also leverage PCB-track specifications provided in the device datasheet to ease design challenges and ensure optimal performance.

The ESD protection provided complies with IEC 61000-4-2 and exceeds level 4: 8 kV for contact discharge and 15 kV for air discharge. The device also withstands 2 kV pulse voltage in accordance with MIL STD 883C.

The product 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 including consumer satellite navigation, radio base stations, drones and tracking of assets or livestock. It is housed in a SOT23-6L package that is compatible with automatic optical inspection.
