RF DetectorWill RF Detectors Measure Up To 3G?From primitive crystal detectors to today's advanced exponential logarithmic amplifiers, RF power detection has come a long way.Rick Cory, Eamon NashMany systems need to measure radio frequency (RF) power. Some examples include communications transceivers, instrumentation, industrial controls, and radar. Sometimes, these RF-power measurements are required to assure compliance with government regulations. In other cases, they help ensure efficient system operation. Over the years, the technology that is used to detect RF-signal levels has improved dramatically. From a primitive-diode beginning, it advanced to multi-function-detector integrated circuits (ICs). Diode rectifier circuits have been used for signal-level detection for almost a century. This……
