RF (Radio Frequency) detectors, also known as RF power detectors and RF responding detectors, are devices designed to detect the manifestation of RF signals in a physical transmission medium, such as wired or wireless RF cables. Available as modules, their main function is to control and measure RF power, mostly in wireless systems. Furthermore, they are also employed to test equipment for their proper functionality, monitoring of signals or noise, and for interference signals’ existence. 

How Many Different Types of RF Detectors are There?

The RF power detectors are divided into two basic types, including:

• Logarithmic Type - These detector types convert the RF input power into a direct current (DC) voltage that is proportional to the input log. 
• RMS Type – These types are designed to generate a DC output proportional to the signal’s RMS value.

What are the Essential Considerations for Choosing RF Detectors?

There are certain parameters before you opt for an RF power detector, such as:

• The RF Signal Type: The most crucial factor for the detector type to be used.  
• The Log Type: Due to rapid response time, the log type is useful for general control, pulsed RF signals, and power measurement applications.  
• Applications: It is crucial to determine the exact use of the correct type of RF detector, especially where the signal with high crest fluctuations factors are better. 

What are the Applications or Environments for RF Detectors Used?

These highly reliable RF responding detectors are widely found in various environments with multiple applications, such as:

• Security systems
• Healthcare
• Receive or transmit power measurement
• Materials Analysis
• Traffic management
• RF pulse detection
• Test and measurement
• Input protection
• Return loss measurement
