Overview
The BFCN-2275+ is a surface-mount LTCC bandpass filter with a center frequency of 2.275 GHz and a bandwidth of 210 MHz. It operates at a 50 Ohm impedance in a compact 4-SMD, no-lead package measuring 3.20mm x 1.60mm x 0.94mm. The device utilizes multilayer ceramic technology for high repeatability and ruggedness.
Feature Summary
- Constructed using multilayer ceramic technology to achieve miniature size and high performance repeatability.
- Wrap-around terminations minimize variations in performance due to parasitics.
- Provides low insertion loss and good rejection at the band-reject edges.
- LTCC construction offers a rugged package suitable for tough environments including high humidity and temperature extremes.
Applications
- Receivers
- Transmitters
- VHF/UHF Receivers/Transmitters
Procurement Notes
Verify the specific ordering suffix (e.g., +) to ensure compliance with RoHS3 standards. Confirm the package type matches the required surface-mount footprint. Check datasheet specifications for center frequency accuracy and bandwidth requirements relative to the application design.
Selection Notes
Select this component for applications requiring a fixed center frequency of 2.275 GHz. Ensure the system impedance is 50 Ohms. Consider the physical dimensions of the 4-SMD package for PCB layout constraints. Verify thermal operating limits against the intended environment.
Part Context
