CBP-1490A+

Overview

The CBP-1490A+ is a ceramic-coaxial-resonator bandpass filter designed for surface-mount technology (SMT) applications. It operates within a passband of 1465 MHz to 1515 MHz, providing a center frequency of 1490 MHz with a bandwidth of 50 MHz. The component features a 50 Ohm impedance and exhibits an insertion loss of 4.5 dB. It utilizes the KV1514 shielded package style and complies with RoHS and REACH standards.

Feature Summary

• Utilizes ceramic-coaxial-resonator construction for stable performance
• Shielded SMT package design minimizes interference
• Provides effective out-of-band rejection in specified stopbands

Applications

• Wireless communication systems requiring signal conditioning
• RF front-end modules in mobile infrastructure
• Test and measurement instrumentation filters

Procurement Notes

Verify the specific datasheet version and mechanical drawings from Mini-Circuits or authorized distributors before integration. Confirm that the KV1514 package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS and REACH regulations matches your regional manufacturing standards. Cross-reference the electrical specifications against your system's noise figure and linearity constraints.

Selection Notes

Select this component when a narrow bandpass characteristic around 1.49 GHz is required in a compact surface-mount form factor. Consider the 4.5 dB insertion loss impact on overall system gain. Evaluate the thermal management capabilities of the shielded package if operating near maximum temperature limits. Compare alternative resonator types if lower insertion loss is critical for your application.

Part Context

Mini-Circuits specializes in RF, IF, and microwave signal processing components. The CBP series represents their range of ceramic resonator filters, offering high Q-factor performance in small packages. This model fits within their portfolio of surface-mount solutions for modern wireless communications and industrial electronics.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-references. Verify equivalent part numbers such as those from other manufacturers like Murata or TDK if supply chain diversification is needed. Ensure replacement parts match the 1465-1515 MHz passband and 50 Ohm impedance specifications.
