MBT-44+

Overview

The MBT-44+ is an ultra-wideband MMIC bias tee from Mini-Circuits, designed for surface mount applications. It operates within a frequency range of 10 GHz to 40 GHz. The component supports a maximum voltage of 35 Volts and a maximum current of 500 mA. It handles up to 1 Watt of power with an insertion loss ranging from 0.2 dB.

Feature Summary

• Ultra-wideband MMIC design covering 10 GHz to 40 GHz
• Low insertion loss performance
• Good return loss characteristics
• Surface mount package configuration

Applications

• RF signal distribution systems requiring DC bias injection
• Microwave measurement setups
• High-frequency test and evaluation boards

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant, such as connectorized or bare die options, matches the intended PCB layout requirements. Confirm that the operating environment stays within the specified 35V and 500mA limits to maintain device integrity and performance stability during operation.

Selection Notes

Select this component when a wide bandwidth extending up to 40 GHz is required for biasing RF circuits. Ensure the application can accommodate the surface mount form factor and that the thermal management strategy aligns with the 1W power handling capability. Validate impedance matching needs against the low insertion loss specification.

Part Context

This part belongs to Mini-Circuits' line of RF, IF, and microwave components spanning DC to 86GHz. The MBT series provides essential biasing solutions for active devices in high-frequency environments. The '+' suffix indicates compliance with RoHS standards.

Replacement Considerations

Check for the MBT-44-D+ variant if a die version is preferred over the packaged module. Verify compatibility with existing board space and soldering profiles before substituting.
