FMBT1642

Overview

The FMBT1642 is a broadband bias tee manufactured by Fairview Microwave, designed for RF applications up to 40 GHz. It features SMA connectors with a male input and a BNC DC output. The device operates within a frequency range of 12 kHz to 40 GHz and maintains a 50 Ohm impedance. It is rated for a maximum current of 150 mA and a voltage of 16 Volts on the DC port. The unit utilizes chassis mounting and is packaged individually in bags.

Feature Summary

• Integrates RF signal path with DC bias injection capability
• Supports high-frequency operation extending to 40 GHz
• Provides isolated DC input via BNC connector

Applications

• Biasing active RF components such as amplifiers
• Test and measurement setups requiring combined DC and RF signals
• Microwave circuit characterization

Procurement Notes

Verify the specific connector gender and DC rating requirements against the official datasheet before ordering. Confirm that the 150 mA current limit and 16 V voltage rating are sufficient for the intended load. Ensure compatibility with existing SMA infrastructure and check for any regional distribution restrictions or availability constraints from authorized suppliers.

Selection Notes

Select this component when a wide bandwidth up to 40 GHz is required alongside DC biasing. The SMA interface ensures compatibility with standard microwave test equipment. Consider the 150 mA current capacity for low-power active devices. The BNC DC port allows convenient power supply connection without interfering with the RF signal path.
