SXBP-29+

Overview

The Mini-Circuits SXBP-29+ is a surface-mount lumped LC band pass filter designed for RF applications. It operates with a center frequency of 29 MHz and provides an 11 MHz bandwidth, covering the 24 to 35 MHz range. The component features low insertion loss, typically 0.9 dB, and offers wide stopband rejection of 40 dB. It maintains a typical VSWR of 1.4:1 and is optimized for fast rejection roll-off to enhance selectivity against adjacent channels. Packaged in an 8-SMD, no-lead form factor, it supports 50 Ohm systems.

Feature Summary

• Fast rejection roll-off enables effective rejection of adjacent channels with increased selectivity
• Compact surface-mount design suitable for space-constrained electronic assemblies
• Low insertion loss ensures minimal signal attenuation within the passband

Applications

• Communications systems requiring specific frequency filtering
• Test and measurement equipment for signal conditioning
• RF front-end modules needing channel isolation

Procurement Notes

Verify the exact part number suffix and package variant when ordering. Confirm that the 8-SMD no-lead footprint matches your PCB layout requirements. Ensure compatibility with 50 Ohm system impedance. Check for RoHS compliance status if required by your manufacturing standards. Validate that the operating temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Choose this component when a narrow 11 MHz bandwidth centered at 29 MHz is required. It is suitable for designs prioritizing low insertion loss and high selectivity over wideband performance. Consider the SMD package constraints during layout planning. Evaluate the 40 dB stopband rejection capability against your interference mitigation needs. This filter is appropriate for fixed-frequency applications rather than tunable systems.

Part Context

The SXBP series from Mini-Circuits represents a line of compact band pass filters utilizing lumped LC technology. These components are engineered for high reliability and consistent performance in RF environments. The SXBP-29+ specifically targets the 24-35 MHz range, offering a balance between size and electrical performance. It is part of a broader portfolio designed for communications and test applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical parameters carefully if considering alternative manufacturers. Ensure any replacement maintains the 50 Ohm impedance and similar bandwidth characteristics.
