AD8363ACPZ-R7

AD8363 is a TruPwr™ true rms responding power detector that can be directly driven with a single-ended 50 ohm source. This feature makes this frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 6GHz. This provides an accurate power measurement, independent of waveform, for a variety of high frequency communication and instrumentation systems. Requiring only a single supply of 5V and a few capacitors, it is easy to use and provides high measurement accuracy. It can determine the true power of a high frequency signal having a complex low frequency modulation envelope, or it can be used as a simple low frequency rms voltmeter. Application includes power amplifier linearization/control loops, multi-standard, multi-carrier wireless infrastructure, transmitter power control, transmitter signal strength indication, RF instrumentation.
