FMBT1645

Overview

The FMBT1645 is a broadband bias tee RF adapter manufactured by Fairview Microwave. It operates within a frequency range of 12 kHz to 40 GHz with a 50 Ohm impedance. The device features two 2.92 mm female connectors for the RF path and one BNC female connector for DC bias input. It is rated for a maximum current of 150 mA and a voltage of 16 Volts. The unit has a VSWR of 1.7 and weighs approximately 49.895 grams.

Feature Summary

• Integrates DC bias injection into high-frequency RF signal paths using a three-port tee configuration.
• Supports ultra-wideband operation extending from low kilohertz frequencies up to 40 GHz.
• Provides isolated DC input via a standard BNC connector while maintaining 50 Ohm RF continuity.

Applications

• Biasing active components in millimeter-wave test and measurement setups
• Integrating power into RF circuits requiring operation above 20 GHz
• Signal conditioning in wideband communication system testing

Procurement Notes

Verify the specific datasheet version before integration, as manufacturer specifications may be updated. Confirm that the 150 mA current rating and 16 Volt limit align with your circuit requirements. Ensure compatibility between the 2.92 mm and BNC interfaces in your assembly design.

Selection Notes

Select this component when a bias tee is required for frequencies exceeding standard SMA or K-band limits. The 2.92 mm interface ensures performance stability at higher frequencies compared to lower-grade connectors. Verify that the chassis mount style fits your enclosure constraints.
