SXBP-640+

Overview

The SXBP-640+ is a surface-mount lumped LC bandpass filter manufactured by Mini-Circuits. It operates with a center frequency of 640 MHz and provides an 80 MHz bandwidth, covering the range from 600 to 680 MHz. The component features a nominal insertion loss of 5 dB and is designed for 50 Ohm systems. It utilizes an 8-SMD, no-lead package suitable for automated assembly. The device supports an operating temperature range of -40°C to 85°C and a storage temperature range of -55°C to 100°C.

Feature Summary

• Surface-mount construction using lumped LC technology
• Designed for 50 Ohm RF signal paths
• Operates within specified industrial temperature limits

Applications

• RF front-end filtering in communication systems
• Signal conditioning in test and measurement equipment
• Frequency selection in S-band upconverter assemblies

Procurement Notes

Verify the specific datasheet version and electrical parameters directly with Mini-Circuits or authorized distributors before integration. Confirm that the 8-SMD package footprint matches your PCB design constraints. Ensure environmental ratings meet your operational requirements. Cross-reference part numbers to avoid confusion with similar models in the SXBP series.

Selection Notes

Select this component when a fixed center frequency of 640 MHz is required with moderate selectivity. The lumped LC design offers a compact form factor compared to distributed line filters. Consider the 5 dB insertion loss impact on system noise figure. Evaluate thermal management needs given the specified operating temperature range.

Part Context

This component belongs to the SXBP series of surface-mount bandpass filters from Mini-Circuits. The series covers various frequency ranges using lumped LC architectures. These filters are intended for general-purpose RF applications where size and cost efficiency are prioritized over ultra-high performance metrics found in cavity or waveguide alternatives.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes within the SXBP series. Verify compatibility of pinout and impedance matching if replacing with components from other manufacturers.
