RLM-23+

Overview

The RLM-23+ is a surface-mount RF limiter designed by Mini-Circuits to protect sensitive receiver circuits from damage caused by high-power unwanted signals. It operates within a frequency range of 950 MHz to 2050 MHz and can handle continuous wave input power up to 1 W. The device features a very low limiting output power and an extremely fast response time of 2 nanoseconds. Constructed on microstrip technology, it ensures reliable performance across a wide temperature range, with a minimum operating temperature of -40°C.

Feature Summary

• Provides protection against damage from strong unwanted signals
• Features very fast response time for immediate signal limiting
• Maintains very low limiting output power during operation

Applications

• Receiver front-end protection in communication systems
• Defense and aerospace radar systems
• Wireless infrastructure equipment

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update specifications over time. Confirm that the + suffix indicates RoHS compliance and lead-free construction. Ensure the surface-mount package style matches your PCB design requirements before finalizing procurement.

Selection Notes

Select this component when broad bandwidth coverage between 950 MHz and 2050 MHz is required alongside robust power handling capabilities. The fast 2 nsec response time makes it suitable for applications requiring rapid protection against transient high-power events. Consider the surface-mount form factor for compact circuit integration.
