BPF1608LKQDR5000L

Overview

The BPF1608LKQDR5000L is a bandpass filter manufactured by Pulse Electronics, designed for signal conditioning applications. It operates within a passband of 5150 MHz to 5925 MHz, centered at 5.5375 GHz with a bandwidth of 775 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type in a 0603 (1608 metric) package. It has a three-pin configuration and supports board mounting. The device functions reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Provides selective frequency filtering for the 5 GHz Wi-Fi spectrum
• Compact surface-mount design suitable for space-constrained PCB layouts
• Maintains stable performance across industrial temperature ranges

Applications

• 5 GHz wireless local area network (WLAN) systems
• Wi-Fi 6 and Wi-Fi 6E client devices
• Mobile broadband communication modules

Procurement Notes

Verify the specific suffix 'QD' against official datasheets to confirm pinout and electrical characteristics match your schematic requirements. Ensure compatibility with standard reflow soldering profiles for 0608 packages. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a narrow bandpass response is required specifically for the 5.15-5.925 GHz range. The 0603 footprint offers a balance between parasitic minimization and assembly ease. Compare insertion loss specifications against system link budget requirements to ensure adequate signal integrity without excessive attenuation.

Part Context

This part belongs to Pulse Electronics' RF filter portfolio, specifically engineered for high-frequency signal conditioning. It complements other components in the same series, such as diplexers and low-pass filters, to form complete front-end modules for modern wireless communication standards requiring precise spectral management.

Replacement Considerations

Direct substitutes include the BPF1608LRAAR4700L for different frequency targets or the LPF1608LWCPR5000L for filtering variations. Verify that any alternative maintains the 0603 footprint and 50 Ohm impedance to prevent impedance mismatch issues in existing designs.
