Product details
Overview
BPF8089-01SC6 from STMicroelectronics is a GNSS front-end bandpass filter with integrated ESD protection and 50 Ω input impedance matching, designed specifically for use between antenna and STA8089/STA8090 LNA inputs. It operates across 1559–1610 MHz (GPS L1/Galileo E1/BeiDou B1/QZSS L1), delivers ≤5 dB insertion loss, ≥13 dB input/output return loss, and withstands ±8 kV contact / ±15 kV air discharge per IEC 61000-4-2.
For engineers reviewing the BPF8089-01SC6 datasheet, BPF8089-01SC6 pinout, BPF8089-01SC6 application, or BPF8089-01SC6 equivalent, this device serves as a purpose-built impedance-matching and ESD-hardened interface for GNSS receiver front-ends - critical for portable navigation, asset tracking, and high-reliability timing modules where antenna-LNA coupling integrity and electrostatic robustness are design-critical.
Technical Context
This device implements a passive, surface-mount RF bandpass filter network optimized for conjugate matching between 50 Ω antenna sources and the complex input impedance of STA8089/STA8090 low-noise amplifiers. Its topology integrates ESD protection diodes directly into the signal path without compromising passband flatness or group delay stability.
It satisfies MIL-STD-883C (2 kV, 100 pF/1.5 kΩ) and IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air), with no DC bias required and full compatibility with automated optical inspection (AOI) due to SOT23-6L footprint compliance per IPC-7531 and JEDEC MO-178.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 1559–1610 MHz - Covers full GPS L1, Galileo E1, GLONASS G1, BeiDou B1, and QZSS L1 bands in a single passband. |
| Insertion Loss | 2.4–5 dB typ/max - Ensures minimal SNR degradation between antenna and LNA while maintaining filtering selectivity. |
| Input Return Loss | ≥13 dB - Guarantees <−13 dB reflection at antenna port, enabling stable 50 Ω system interface. |
| Output Return Loss | ≥13 dB - Matches conjugate impedance of STA8089/STA8090 LNA inputs to minimize signal reflection. |
| ESD Withstand (Contact) | ±8 kV per IEC 61000-4-2 - Protects LNA input from EOS damage during handheld device handling or antenna connector mating. |
| Package | SOT23-6L - Standardized 6-pin leaded package with 0.95 mm pitch, AOI-compatible, MSL Level 1 rated. |
Pinout & Package
Package: SOT23-6L - 6-pin plastic surface-mount package with dimensions D = 2.8–3.05 mm, E = 1.5–1.75 mm, body height A2 = 0.9–1.3 mm, and 0.95 mm pin pitch. Compliant with JEDEC MO-178 and IPC-7531 land pattern recommendations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RF IN) | Antenna-side RF input | Accepts 50 Ω-matched GNSS signal; connects directly to antenna feed point or external SAW filter output. |
| 2 (GND) | Ground reference | Dedicated RF ground connection; must be tied to low-inductance PCB ground plane adjacent to RF path. |
| 3 (NC) | No-connect terminal | Internally unconnected; must remain unconnected on PCB - no trace or pad attachment permitted. |
| 4 (GND) | Ground reference | Second dedicated RF ground; improves grounding symmetry and reduces common-mode coupling in differential-sensitive layouts. |
| 5 (RF OUT) | LNA-side RF output | Drives STA8089/STA8090 LNA input with conjugate-matched impedance; requires controlled 50 Ω microstrip routing. |
| 6 (STA GND) | LNA ground reference | Provides isolated ground return path for LNA side; recommended to tie to same ground plane as pins 2 and 4 via short low-inductance route. |
Key Features
| Feature | Design Value |
|---|---|
| GNSS-band optimized matching | Conjugate match to STA8089/STA8090 LNA input impedance - eliminates need for discrete matching components in reference designs. |
| Integrated ESD protection | Passive diode-based protection meeting IEC 61000-4-2 Level 4 and MIL-STD-883C - protects LNA without adding DC bias or control logic. |
| SOT23-6L footprint compatibility | JEDEC MO-178 registered package with IPC-7531 land pattern - enables drop-in placement in high-volume automated assembly lines. |
| Lead finish | NiPdAu plating - ensures solderability, wire-bond compatibility, and long-term corrosion resistance under humid operating conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS front-end matching and ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11032 | Wider bandwidth (1550–1615 MHz); higher IL (≤6.5 dB); no integrated ESD diodes - requires external TVS. | Used in dual-band (L1+L5) receivers; lacks built-in ESD hardening for single-L1 portable designs. | Select when broader frequency margin is needed and board space allows discrete ESD protection. |
| Infineon BGU7005 | Lower IL (≤3.5 dB typ); narrower bandwidth (1570–1580 MHz); no NC pin - 5-pin SOT363 package. | Optimized for GPS-only applications; insufficient coverage for Galileo/BeiDou multi-constellation operation. | Select only for legacy GPS-only designs where multi-constellation support is not required. |
Compared with QM11032 and BGU7005, BPF8089-01SC6 uniquely combines full multi-constellation bandwidth, integrated ESD protection, and exact STA8089/STA8090 conjugate matching - making it the only drop-in solution for ST's GNSS reference platforms without layout redesign or component count increase.

FAQ
Is BPF8089-01SC6 compatible with both STA8089 and STA8090 GNSS receivers?
Yes. The device is explicitly designed to provide conjugate impedance matching to both STA8089 and STA8090 LNA inputs, as confirmed in DS13416 Rev 2 Section 2. Electrical characteristics specify ZOUT as "conjugate match to STA8089 and STA8090 LNA IN". Layout recommendations in Figures 6–8 further validate its use across multiple variants of both IC families.
Can Pin 3 (NC) be grounded or left floating on the PCB?
Pin 3 must remain unconnected - physically and electrically isolated - on the PCB. The datasheet states it is "internally not connected and not to be connected on PCB". Grounding or routing to any net violates the specified usage and may degrade RF performance or cause unintended parasitic coupling in the matching network.
What is the maximum RF input power this device can handle continuously?
The absolute maximum RF input power is 0 dBm (1 mW), as specified in Table 1 of DS13416 Rev 2. This rating applies under continuous wave (CW) conditions at Tamb = 25 °C. Exceeding this level risks thermal overstress of internal passive elements and potential shift in center frequency or insertion loss.
Does BPF8089-01SC6 require external DC bias or control signals?
No. BPF8089-01SC6 is a fully passive device with no active circuitry, no bias pins, and no enable/control terminals. It operates without power supply, DC blocking capacitors, or matching inductors - functioning solely as a matched bandpass filter and ESD protection network between antenna and LNA.
