Overview
The BFCN-1445+ is an LTCC bandpass filter with a center frequency of 1.445 GHz and a bandwidth of 50 MHz. It operates at a nominal impedance of 50 Ohms and utilizes a 4-SMD, No Lead package. The device employs 12-layer LTCC construction to ensure high repeatability and miniature size.
Feature Summary
- Constructed using multilayer ceramic technology for ruggedness in high humidity and temperature extremes
- Wrap-around terminations minimize performance variations caused by parasitics
- Provides low insertion loss and good rejection at band-reject edges
Applications
- S-band upconverter assemblies
- RF signal conditioning circuits
- Microwave communication systems
Procurement Notes
Verify the specific datasheet version for the BFCN-1445+ to confirm exact electrical parameters and mechanical dimensions. Ensure compatibility with SMD soldering profiles. Confirm that the 50 Ohm impedance matches system requirements. Check for any specific handling instructions related to the LTCC material and wrap-around terminations during assembly.
Selection Notes
Select this component when a compact, high-repeatability bandpass filter is required for S-band applications. The LTCC construction offers durability in harsh environments compared to other filter types. Consider the 4-SMD no-lead package for surface-mount integration. Evaluate the 50 MHz bandwidth against system spectral requirements.
Part Context
This component belongs to the Mini-Circuits BFCN series of LTCC bandpass filters. These filters are designed for miniature size and high repeatability. The series utilizes multilayer ceramic technology to achieve rugged performance suitable for tough environments, including high humidity and temperature extremes.
Replacement Considerations
Consult official Mini-Circuits documentation for verified substitute part numbers within the BFCN series or equivalent LTCC bandpass filters. Do not assume interchangeability based on similar center frequencies without verifying impedance, bandwidth, and package compatibility.
