GENERAL DESCRIPTION The AD8363 is a true RMS responding power detector that has more than 50 dB measurement range when driven with a single-ended 50 Ω source. The device provides a solution in a variety of high frequency communication systems, and in instrumentation, requiring an accurate response to signal power. The AD8363 is easy to use with its single-ended 50 Ω input, only requiring a single 5 V supply, and a few capacitors. The AD8363 can operate from arbitrarily low frequencies to 6 GHz and can accept inputs that have RMS values from less than -50 dBm to at least 0 dBm, with large crest factors, exceeding the requirements for accurate measurement of WiMAX, WCDMA, and CDMA signals. The AD8363 can determine the true power of a high frequency signal having a complex low frequency modulation envelope, or can be used as a simple low frequency RMS voltmeter. The high-pass corner generated by its internal offset-nulling loop can be lowered by a capacitor added on the CHPF pin. Used as a power measurement device, VOUT is connected to VSET. The output is then proportional to the logarithm of the RMS value of the input. In other words, the reading is presented directly in decibels and is conveniently scaled 1 V per decade, or 50 mV/dB; other slopes are easily arranged. In controller mode, the voltage applied to VSET determines the power level required at the input to null the deviation from the set point. The output buffer can provide high load currents. The AD8363 has 1.5 mW power consumption when powered down by a logic high applied to pin 1, TCM2. It powers up within about 30 μs to its nominal operating current of 60 mA at 25°C. The AD8363 is supplied in a 4 mm x 4 mm, 16-lead LFCSP for operation over the temperature range of −40°C to +125°C. An evaluation board is available. |
