FMBT1649

Overview

The FMBT1649 is a Type N 75 Ohm Bias Tee manufactured by Fairview Microwave. It operates within a frequency range of 10 MHz to 3 GHz. The component is rated for a maximum current of 2.5 Amps and a voltage of 100 Volts on the DC pin. It features a general-purpose design suitable for broadband applications requiring signal injection.

Feature Summary

• Provides DC bias injection capability while maintaining RF signal integrity in 75 Ohm systems.
• Supports high current loads up to 2.5 Amps and voltage ratings of 100 Volts.
• Operates as a broadband adapter covering frequencies from 10 MHz to 3 GHz.

Applications

• Broadband RF signal injection in 75 Ohm transmission lines
• General purpose biasing for RF modules and ICs
• Test and measurement setups requiring combined DC and RF signals

Procurement Notes

Verify that the specific application requires a 75 Ohm impedance match, as this component differs from standard 50 Ohm bias tees. Confirm that the DC voltage and current requirements do not exceed the 100 Volt and 2.5 Amp ratings respectively. Ensure connector compatibility with existing Type N infrastructure before procurement.

Selection Notes

Select the FMBT1649 when system architecture mandates a 75 Ohm characteristic impedance rather than the more common 50 Ohm standard. This model is appropriate for applications needing higher current handling capabilities up to 2.5 Amps. Consider the 10 MHz to 3 GHz operational bandwidth to ensure it covers the required signal spectrum without attenuation issues.

Part Context

This component belongs to the RF Adapters - Tee category, specifically designed as a Bias Tee. It integrates DC power delivery with RF signal transmission in a single compact module. The Type N connector interface ensures robust mechanical connection and reliable performance in industrial and broadcast environments.
