MAR-2SM+

Overview

The MAR-2SM+ is a wideband InGaP HBT MMIC amplifier from Mini-Circuits, offering high dynamic range and repeatable performance. It operates from DC to 2000 MHz with a maximum gain of 12.5 dB. The device requires a 5 V operating voltage and draws 25 mA of current, resulting in 325 mW dissipated power. Enclosed in a Micro-X package, it is RoHS compliant and designed for linear applications requiring consistent lot-to-lot reliability.

Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when sourcing. Confirm the Micro-X package type matches your PCB footprint requirements. Ensure the design supports the specified 5 V supply and 25 mA current draw. Check for any updated datasheet revisions that may affect electrical parameters or pin configurations before finalizing the bill of materials.

Selection Notes

Select this component for applications requiring a linear gain block from DC to 2 GHz. The InGaP HBT technology provides stable performance without the complexity of GaAs. Consider the 12.5 dB max gain and 325 mW power dissipation when designing thermal management solutions. Verify system impedance matching for optimal noise figure and gain flatness across the wide bandwidth.

Part Context

The MAR-2SM+ belongs to the MAR series of RF amplifiers from Mini-Circuits, a global leader in RF and microwave components. This series utilizes HBT technology for linear amplification. The manufacturer offers extensive support including ECAD models and library loaders for integration into design workflows, serving industries from telecommunications to aerospace.

Replacement Considerations

Public confirmed substitutes include other MAR series variants such as MAR-8SM+. Verify frequency range and gain specifications match application needs before substitution.
