SXBP-20R5+

Overview

The SXBP-20R5+ is a narrow-band bandpass RF filter fabricated using surface mount technology (SMT). It operates within the 20 MHz to 21 MHz frequency range, providing a center frequency of 20.5 MHz with a 3 dB bandwidth of 1 MHz. The component features an impedance of 50 Ohms and is housed in an 8-SMD, no-lead package. Designed for high reliability, it utilizes miniature high Q capacitors and wire-welded inductors. Typical voltage standing wave ratio (VSWR) is 1.3:1 in the passband, ensuring good return loss and interface performance.

Feature Summary

• Narrow-band bandpass filtering capability utilizing SMT fabrication
• High reliability construction with miniature high Q capacitors and wire-welded inductors
• Good matching characteristics with typical VSWR of 1.3:1 in the passband

Applications

• Radio frequency signal conditioning

Procurement Notes

Verify the specific part number SXBP-20R5+ against official Mini-Circuits documentation to confirm technical specifications. Ensure compatibility with 50 Ohm system impedance requirements. Check for RoHS and REACH compliance status as indicated in current datasheets. Confirm package type matches the 8-SMD no-lead configuration required for your assembly process.

Selection Notes

Select this component when a narrow 1 MHz bandwidth is required around the 20.5 MHz center frequency. It is suitable for applications demanding high reliability and repeatable performance due to its specialized internal construction. Consider the 8-SMD package size constraints during PCB layout design. Ensure the operating environment supports the specified electrical parameters without exceeding limits.

Part Context

This component belongs to the SXBP series of bandpass filters from Mini-Circuits. These filters are designed for radio frequency applications requiring precise frequency selection. The series utilizes advanced SMT technology to achieve compact form factors while maintaining high performance metrics such as low insertion loss and good return loss across the designated passband.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Ensure any replacement maintains the 20.5 MHz center frequency and 1 MHz bandwidth specifications. Verify that the substitute component offers compatible 50 Ohm impedance and similar physical dimensions for direct board integration.
