SXBP-70+

Overview

The SXBP-70+ is a lumped LC bandpass filter designed for radio frequency applications. It operates with a center frequency of 70 MHz and provides a bandwidth of 14 MHz, covering the range from 63 to 77 MHz. The component features an insertion loss of 1.5 dB and is engineered for 50 Ohm systems. It utilizes an SMD surface-mount package without leads, facilitating integration into compact circuit designs.

Feature Summary

• Fast rejection roll-off enables effective rejection of adjacent channels with increased selectivity
• Lumped LC construction provides high performance in a compact surface-mount form factor
• Designed for high rejection applications requiring precise signal filtering

Applications

• Military hi-rel systems
• Image rejection circuits
• IF signal processing
• High rejection RF applications

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct electrical specifications and package type. Confirm that the required operating temperature range and power handling capabilities align with your system design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a narrow bandpass characteristic around 70 MHz is required. The 14 MHz bandwidth suits applications needing precise channel selection. Ensure the PCB layout supports the no-lead SMD footprint and maintains 50 Ohm impedance matching for optimal signal integrity.

Part Context

This component belongs to the SXBP series of bandpass filters manufactured by Mini-Circuits. The series offers various center frequencies tailored for different RF and IF stages. These filters are characterized by their lumped element design, which allows for smaller physical dimensions compared to distributed line filters while maintaining sharp cutoff characteristics.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalent parts. Cross-reference center frequency, bandwidth, and insertion loss parameters to ensure functional compatibility within the target circuit design.
