Analog Devices Introduces Wide-Dynamic-Range RF Power Detectors with High Temperature Stability

Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications, today introduced two RF power detectors with wide dynamic range and best-in-class accuracy and temperature stability.

Designed with ADI’s leading detector expertise, the ADL5903 RF detector is an optimal solution for a variety of high frequency systems requiring accurate measurement of signal power independent of waveform characteristics. The ADL5506 RF detector is a complete subsystem for the measurement of RF signals in a wide range of wireless terminal devices. Both detectors are offered in small packages with low-power operation, making them ideal for designs that are constrained by space or power.
