BFCV-4085+

Overview

The Mini-Circuits BFCV-4085+ is a ceramic LTCC bandpass filter with a center frequency of 4.085 GHz and a passband range of 3130 to 5040 MHz. It operates at a nominal impedance of 50Ω and utilizes an SMD3225-4P (JV1210C) surface-mount package. The component is designed for RF applications, offering high performance repeatability through its multi-layer construction.

Feature Summary

• Constructed using Low-Temperature Co-fired Ceramic (LTCC) technology for miniature size and high performance repeatability.
• Features a fixed center frequency of 4.085 GHz with a defined passband from 3130 MHz to 5040 MHz.
• Designed for surface mount integration in RF and microwave circuits.

Applications

• RF front-end filtering
• Microwave communication systems
• Signal conditioning in 50Ω environments

Procurement Notes

Verify the specific datasheet version and electrical parameters directly from Mini-Circuits official documentation before integration. Confirm that the JV1210C package dimensions align with your PCB layout requirements. Ensure the operating temperature range specified in the manufacturer's data sheet meets your environmental constraints. Cross-reference the part number BFCV-4085+ to distinguish it from similar models in the BFCV series.

Selection Notes

Select this component when a fixed center frequency near 4.085 GHz is required within a 3130-5040 MHz bandwidth. The LTCC construction offers stability suitable for mass production. Consider the SMD3225-4P footprint for space-constrained designs. Verify impedance matching at 50Ω for system compatibility. This filter is intended for applications requiring precise frequency selection without tunability.

Part Context

The BFCV-4085+ belongs to Mini-Circuits' BFCV series of LTCC bandpass filters. These components are engineered for RF and IF applications up to 86GHz. The series emphasizes compact form factors and reliable performance in microwave frequencies. The '+' suffix typically indicates lead-free compliance in Mini-Circuits nomenclature, though specific RoHS status should be confirmed via the current datasheet.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct replacements. Similar center frequencies may be found in other BFCV models, but bandwidth and package differences must be evaluated. No generic substitutes are recommended due to the specific LTCC design and frequency characteristics.
