BFCN-8350+

Overview

The Mini-Circuits BFCN-8350+ is an LTCC bandpass filter designed for the 8250 MHz to 8450 MHz frequency range, with a center frequency of 8350 MHz. It features a 50 Ohm impedance and operates within a temperature range of -55 °C to +100 °C. Key electrical specifications include a maximum insertion loss of 3.5 dB and a voltage standing wave ratio (VSWR) of 1.4. The device supports an average input power of 2 W and is housed in a miniature hermetically sealed ceramic package measuring 3.2 mm x 1.6 mm x 0.94 mm.

Feature Summary

• Constructed using five-layer LTCC technology to ensure high performance repeatability and compact form factor.

Applications

• Wireless communication systems requiring signal conditioning in the 8 GHz range.

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with surface mount assembly processes given the SMD package type. Confirm RoHS compliance status if required by specific regulatory standards for the target deployment environment.

Selection Notes

Select this component when a narrowband filter is needed for frequencies around 8.35 GHz with strict size constraints. The 50 Ohm impedance matches standard RF transmission lines. Consider the thermal operating limits and power handling capabilities relative to the system's signal levels to ensure reliable operation under varying environmental conditions.

Part Context

This component belongs to Mini-Circuits' line of LTCC bandpass filters, which utilize low-temperature co-fired ceramic technology. These filters are engineered for applications demanding small physical dimensions alongside stable RF performance. The family typically includes various center frequencies tailored for specific microwave and millimeter-wave bands.

Replacement Considerations

Check for BFCN-8350 as a potential variant, noting that suffixes may indicate differences in packaging or testing criteria rather than functional changes. Verify equivalent part numbers from other manufacturers only if they match the 8350 MHz center frequency, 50 Ohm impedance, and 1206-style footprint dimensions.
