RADIO FREQUENCY DIRECTIONAL POWER SENSOR

RADIO FREQUENCY DIRECTIONAL POWER SENSOR

Features

  • Compact – it is small in size as compared to imported
    counterparts
  • Low Power consumption
  • Integrated non-linearity correction
  • Distributed computation through RS 485 interface, If
    required multiple sensors may be daisy chained by
    using a hub

This High Power (500 W) Directional RF Power Sensor with dual channels is a thru line coupler and sensor with built-in digital conversion and scaling of data. The converted data is represented in direct milli-dBm unit and is communicated on standard RS422/485 interface. It is compact in size, accurate, cost efficient. It does not need any meter to monitor RF power. Optionally it can be interfaced to a normal computer.

 
For High Power Radio Frequency (RF) systems, Power Monitoring and Sampling, at different junctions is a necessary process for system commissioning, fault debugging and health monitoring. This task is accomplished with the help of RF Directional Power Sensor. It acts as a single channel plug‐in device in the transmission line of RF systems for providing RF power in forward and reverse directions.
