Overview
The FMBT1648 is a Type N to BNC bias tee adapter manufactured by Fairview Microwave. It operates within a frequency range of 10 MHz to 3 GHz and maintains a characteristic impedance of 75 Ohms. The device features two Type N connectors with normal polarity and one BNC connector for DC injection. It is rated for a maximum current of 2.5 Amps and a voltage of 100 Volts. Designed for chassis mounting, the unit weighs approximately 49.895 grams.
Feature Summary
- Integrates DC signal injection into RF paths via a dedicated BNC port while maintaining 75 Ohm impedance across Type N interfaces.
- Supports high-power DC biasing up to 2.5 Amps and 100 Volts without compromising RF performance in the specified frequency band.
Applications
- RF test and measurement setups requiring simultaneous DC bias and signal transmission
- Antenna feed systems needing integrated power delivery over coaxial lines
- Communication equipment testing involving bias-tee functionality
Procurement Notes
Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with project requirements. Confirm that the physical dimensions align with the designated chassis mounting space. Inspect connectors for mechanical integrity before installation. Ensure the operating environment remains within the rated voltage and current limits to prevent component damage or performance degradation during use.
Selection Notes
Select this component when a 75 Ohm impedance match is required between Type N and BNC interfaces. The 10 MHz to 3 GHz bandwidth suits applications below UHF frequencies. Consider the 2.5 Amp DC rating for power delivery needs. Chassis mounting style dictates integration constraints compared to cable-mounted alternatives.
Part Context
This adapter belongs to the RF adapters category, specifically designed as a bias tee configuration. It facilitates the combination of DC and RF signals in 75 Ohm systems. The design supports standard Type N and BNC interconnects commonly used in broadcast and industrial RF infrastructure.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing system impedance and connector types before attempting any substitution.
