The Mini-Circuits RMK-3-122+ is a coaxial RF limiter designed to protect sensitive receiver components from high-power signals. It effectively reduces the amplitude of strong input signals, preventing damage and ensuring reliable operation of downstream circuitry. This limiter is commonly used in various communication and radar systems where strong signals can potentially overload or damage receivers.

• Low insertion loss
• High power handling capability
• Fast response time
• SMA connectors

Benefits

• Protects sensitive receivers from damage due to high-power signals
• Maintains signal integrity with low insertion loss
• Ensures reliable operation of receiver systems
• Fast limiting response protects against transient signals
• Easy integration with standard SMA connectors

Additional Details

The RMK-3-122+ RF limiter operates by attenuating input signals exceeding a certain threshold level. This threshold is known as the limiting level. When the input signal is below the limiting level, the limiter introduces minimal insertion loss, allowing the signal to pass through relatively unimpeded. However, when the input signal exceeds the limiting level, the limiter activates and significantly attenuates the signal, preventing it from reaching the receiver input at a damaging level.

Key specifications of the RMK-3-122+ include its frequency range, limiting threshold, insertion loss, return loss, and power handling capability. These parameters determine the suitability of the limiter for specific applications. For detailed technical specifications, consult the official Mini-Circuits datasheet for the RMK-3-122+.
