AD8362ARUZ Datasheet

RF Detector


The AD8362ARUZ is a true rms -responding power detector that has a 65 dB measurement range. It is intended for use in a variety of high frequency communication systems and in instrumentation requiring an accurate response to signal power. It is easy to use, requiring only a single supply of 5 V and a few capacitors. It can operate from arbitrarily low frequencies to over 3 .8 GHz and can accept inputs that have rms values from 1 mV to at least 1 V rms, with large crest factors, exceeding the requirements for accurate measurement of CDMA signals. The AD8362 can be used to determine the true power of a high frequency signal having a complex low frequency modulation envelope, or simply as a low frequency rms volt-meter. The high-pass corner generated by its offset- nulling loop can be lowered bya capacitor added on the CHPF pin. It powers up within about 20 µs to its nominal operating current of 20 mA at 25°C. The AD8362 is supplied in a 16-lead TSSOP for operation over the temperature range of − 40°C to + 85 °C. AD8362ARUZ FEATURES • Complete fully calibrated measurement/control system• Accurate rms -to- dc conversion from 50 Hz to 3.8 GHz • Input dynamic range of >65 dB: − 52dBm to +8dBm in 50Ω• Waveform and modulation independent, such as GSM/CDMA/TDMA• Linear -in - decibels output, scaled 50 mV/dB• Law conformance error of 0.5 dB• All functions temperature and supply stable• Operates from 4.5 V to 5.5 V at 24 mA • Power - down capability to 1.3 mW AD8362ARUZ APPLICATIONS• Power amplifier linearization/control loops• Transmitter power controls• Transmit ter signal strength indication (TSSI) • RF instrumentation
