BFCQ-2702+

Overview

The Mini-Circuits BFCQ-2702+ is an LTCC bandpass filter designed for signal conditioning applications. It operates within a frequency range of 22 GHz to 31 GHz, with a center frequency of 26.1 GHz and a bandwidth of 9 GHz. The component features a 50 Ohm impedance and utilizes SMD/SMT termination styles. It is housed in the NL1008C-7 package, measuring 2.5mm x 2mm. The device supports board mounting and functions within a temperature range of -55°C to +125°C. Insertion loss is specified at 1.5 dB, and it can handle up to 1W of RF input power.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust signal filtering
• Supports high-power RF input handling up to 1W
• Features surface-mountable pick-and-place standard case design

Applications

• RF signal conditioning in microwave systems
• Bandpass filtering in wireless communication infrastructure
• Test and measurement equipment requiring precise frequency selection

Procurement Notes

Verify the specific datasheet version for the BFCQ-2702+ to confirm exact insertion loss and power handling specifications, as values may vary by revision. Ensure compatibility with the NL1008C-7 footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a wide 9 GHz bandwidth is required between 22 GHz and 31 GHz. The 1.5 dB insertion loss offers efficient signal transmission compared to higher-loss alternatives. The 50 Ohm impedance matches standard RF system requirements. Consider the 1W power handling capability for high-power applications where lower-rated filters might fail.

Part Context

This part belongs to the BFCQ series from Mini-Circuits, which specializes in LTCC bandpass filters. These components are engineered for high performance in microwave frequencies. The series is known for combining ceramic filter benefits with surface-mount convenience, suitable for compact electronic designs requiring reliable frequency selection.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative Mini-Circuits BFCQ series parts only if they match the 22-31 GHz range and 50 Ohm impedance exactly.
