Overview
The BFHK-5001+ is an LTCC SMT bandpass filter with a passband of 4.5 to 5.3 GHz and a center frequency of 4.9 GHz. It features an 800 MHz bandwidth, 4.5 dB insertion loss, and operates at 50 ohms. The component utilizes Mini-Circuits' proprietary LTCC material system for miniature size and repeatable performance. It is housed in the NM1812C-3 case style.
Feature Summary
- Utilizes proprietary LTCC material system for high repeatability
- Designed for miniature surface-mount applications
- Provides stopband rejection typically between 90dB and 100dB
Applications
- S-band upconverter assemblies
- RF signal conditioning circuits
- Microwave communication systems
Procurement Notes
Verify the specific datasheet version and parameter tolerances directly from Mini-Circuits official documentation before integration. Confirm that the NM1812C-3 package dimensions align with your PCB layout constraints. Ensure operating conditions remain within the specified electrical limits to maintain performance stability.
Selection Notes
Select this component when a compact, high-rejection filter is required for the 4.5 to 5.3 GHz range. The LTCC construction offers advantages in size and consistency compared to traditional technologies. Evaluate insertion loss and physical footprint requirements against alternative filter types in the same frequency band.
Part Context
This part belongs to the BFHK series of bandpass filters from Mini-Circuits, which covers frequencies from 4.5 GHz to 23.8 GHz. The series is characterized by its use of LTCC technology to achieve small form factors and reliable performance in RF and microwave environments.
Replacement Considerations
Check for direct substitutes within the BFHK series or other Mini-Circuits LTCC filters that match the 4.5-5.3 GHz passband and 1812 package. Verify equivalent electrical specifications such as insertion loss and rejection levels before substitution.
