Selecting an RF or Microwave Power Sensor/Meter

Power measurements are fundamental to the development cycle of any RF or microwave product, from ubiquitous mobile phones to sophisticated radar systems. Not surprisingly, along with the applications, the range of modulation and multiplexing schemes also varies widely. This fact, combined with the availability of new functions in power meters previously reserved for higher-end analyzers, makes the choice of an RF or microwave power measurement system more complex than ever. Due to the large variance in product offerings and specifications on manufacturer’s data sheets, a side by side comparison is the best way to evaluate power sensors before making a purchasing decision.

This application note will describe some of the factors to consider when purchasing a USB power sensor.
