BPJC-542R+

Overview

The BPJC-542R+ is an LTCC bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 4900 to 5900 MHz and features a 50 Ohm impedance. The device utilizes a surface-mount 0603 package with four pads. Key electrical specifications include a bandwidth of 1 GHz and an insertion loss of 1.5 dB.

Feature Summary

• LTCC construction for compact surface-mount integration
• Bandpass filtering optimized for high-band Wi-Fi applications

Applications

• Wi-Fi high-band signal conditioning
• RF front-end modules requiring bandpass filtering

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update component revisions. Confirm that the 0603 footprint matches your PCB layout requirements. Ensure compatibility with standard SMT reflow processes. Check for RoHS compliance status if required by your manufacturing standards. Validate the 50 Ohm system impedance match for your specific circuit design.

Selection Notes

Select this component when a compact bandpass filter is needed for the 4.9 to 5.9 GHz range. The 0603 size suits space-constrained designs. Consider the 1.5 dB insertion loss impact on system noise figure. Evaluate thermal management needs for high-power environments. Compare against other LTCC options for similar frequency coverage.

Part Context

This part belongs to Mini-Circuits' JC series of LTCC filters. These components are designed for high-reliability RF applications. The series offers various frequency bands in small form factors. The BPJC-542R+ specifically targets wireless communication bands. It represents a standard solution for filtering in modern mobile devices.

Replacement Considerations

Check for direct substitutes like the BPGE-542R+ from the same manufacturer. Verify pinout and electrical parameter compatibility before substitution. Ensure the replacement maintains the 0603 package dimensions. Confirm identical passband characteristics for circuit integrity.
