SXBP-1940+

Overview

The SXBP-1940+ is a wideband bandpass filter designed for asymmetric rejection applications. It operates within a frequency range of 1710 to 2170 MHz, centered at 1.94 GHz with a bandwidth of 460 MHz. The component features a 50 Ohm impedance and utilizes a miniature shielded surface-mount package (8-SMD, No Lead). Key electrical characteristics include fast roll-off on the upper sideband, good matching, and low insertion loss of approximately 2 dB in the pass band.

Feature Summary

• Wideband bandpass filtering capability covering 1710 to 2170 MHz
• Miniature shielded surface-mount package design
• Fast roll-off on the upper sideband for asymmetric rejection
• Low insertion loss and good matching within the pass band

Applications

• Asymmetric rejection applications in RF systems
• S-band upconverter designs
• Wireless communication infrastructure filters

Procurement Notes

Verify the exact part number suffix (+) indicates lead-free compliance as per Mini-Circuits standards. Confirm the package type matches the required PCB footprint, specifically the 8-SMD no-lead configuration. Ensure the operating frequency range aligns with the 1710-2170 MHz specification for your specific application requirements before ordering.

Selection Notes

Select this component when asymmetric spectral rejection is required alongside wideband coverage. The SMT package suits automated assembly processes. Consider the 2 dB insertion loss and 460 MHz bandwidth against system sensitivity needs. Verify that the 50 Ohm impedance matches the surrounding circuit topology to ensure optimal signal transmission and minimal reflection.

Part Context

This component belongs to Mini-Circuits' SXBP series of lumped LC bandpass filters. These components are engineered for high performance in RF and microwave applications. The series emphasizes compact form factors suitable for modern electronic devices requiring efficient spectrum management and signal integrity in constrained spaces.

Replacement Considerations

ZX75BP-1940-S+ offers similar frequency coverage but in a rugged connectorized package rather than surface mount.
