STMicroelectronics Presents New IC for Portable GNSS Receivers

STMicroelectronics has introduced new IC BPF8089-01SC6 RF front-end for Global Navigation Satellite System (GNSS) receivers, which simplifies design and saves real-estate by integrating the impedance-matching and electrostatic-discharge (ESD) protection circuitry typically implemented using discrete components.

GNSS ReceiversThe BPF8089-01SC6 provides a 50Ω matched interface between the  GNSS 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 ESD protection provided complies with IEC 61000-4-2 (C = 150pF, R = 330Ω) and exceeds level 4: 8kV for contact discharge and 15kV for air discharge. The device also withstands 2kV pulse voltage in accordance with MIL STD 883C (C = 100pF, R = 1.5kΩ).

The BPF8089-01SC6 is suitable for use in portable satellite receivers for GPS, Galileo, GLONASS, BeiDou, and QZSS constellations, which may be used in many applications including consumer satellite navigation, radio base stations, drones, and tracking of assets or livestock.

Part of ST’s ASIP (Application Specific Integrated Passives) product range, the BPF8089-01SC6 is housed in a SOT23-6L package that is compatible with the automatic optical inspection.
