Overview
The BFCN-2910+ is a surface-mount LTCC bandpass filter designed for high-reliability applications. It operates with a center frequency of 2910 MHz and supports a frequency range from 2.85 GHz to 2.97 GHz. The device features a 50 Ohm impedance and utilizes a 4-SMD, no-lead package construction.
Feature Summary
- Constructed using Low-Temperature Co-fired Ceramic (LTCC) technology for miniature size and high repeatability
- Designed as a space-qualified RF filter component
- Provides balanced-to-unbalanced transformation capabilities within the specified frequency band
Applications
- Space qualified RF systems
- Satellite communication infrastructure
- Wideband push-pull amplifiers
Procurement Notes
Verify the specific datasheet version when sourcing, as Mini-Circuits may update pin configurations or mechanical dimensions over time. Confirm that the 'space-qualified' designation aligns with your mission requirements, as this implies specific testing standards beyond standard commercial components. Ensure the 4-SMD footprint matches your PCB layout constraints precisely before finalizing procurement orders.
Selection Notes
Select this component when a compact, high-performance bandpass filter is required for frequencies around 2.91 GHz. The LTCC construction offers superior thermal stability and miniaturization compared to traditional ceramic filters. Consider the 50 Ohm system impedance match for seamless integration into standard RF transmission lines without additional matching networks.
Part Context
This part belongs to the BFCN series of LTCC bandpass filters from Mini-Circuits. These components are engineered for demanding environments where size, weight, and power efficiency are critical. The series typically serves microwave and millimeter-wave applications requiring precise frequency selection and rejection characteristics.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. Evaluate alternative Mini-Circuits models within the BFCN series if center frequency adjustments are acceptable.
