MAR-1SM+

Overview

The MAR-1SM+ is a wideband monolithic amplifier from Mini-Circuits, fabricated using InGaP HBT technology in a Micro-X package. It operates from DC to 1000 MHz with a maximum gain of 17.8 dB. The device requires a 5 V operating voltage and draws 17 mA of current, resulting in 200 mW dissipated power. It utilizes a Darlington configuration to deliver high dynamic range and repeatable performance across production lots.

Feature Summary

• Utilizes InGaP HBT technology for robust signal amplification
• Employs Darlington configuration to enhance dynamic range
• Enclosed in a compact Micro-X surface-mount package

Applications

• Cellular infrastructure systems
• Wideband RF signal processing chains
• Test and measurement equipment front ends

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact electrical tolerances and RoHS compliance status. Ensure the Micro-X footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a DC-coupled wideband solution is required up to 1 GHz. The low 17 mA current draw makes it suitable for power-sensitive designs. Confirm that the 5 V supply rail aligns with your system architecture and that the Micro-X package size fits within the available board space.

Part Context

This part belongs to the MAR series of monolithic amplifiers designed for general-purpose RF applications. The series emphasizes consistent lot-to-lot performance and high reliability, with an expected MTTF of 15,000 years at 85°C. The MAR-1SM+ specifically targets wideband needs within the cellular and wireless communication sectors.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalents. Generic replacements may not match the specific InGaP HBT characteristics or Micro-X form factor.
