The AD8362 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 operates from arbitrarily low frequencies to over 3.8 GHz and accepts inputs from -52 dBm to +8 dBm with crest factors that are typical of quadrature amplitude modulation (QAM) and orthogonal frequency division multiplexing (OFDM) modulation schemes. Features: Complete, fully calibrated measurement/control system Accurate rms to DC conversion (50 Hz to 3.8 GHz) Input dynamic range greater than 65 dB: -52dBm to +8dBm (50 ) Independent of waveform and modulation, such as GSM/CDMA/TDMA Linear dB output, adjustment ratio: 50mV/dB Excellent temperature and power stability for all functions Low power consumption of 1.3mW, it helps save electricity Specifications: Working voltage: 4.5 V to 5.5 V (24 mA) Board working frequency : 0.1 ~ 3.8GHz Chip frequency: 50 Hz to 3.8 GHzRule Consistency Error: 0.5 dB Input impedance: 50 OhmsOutput impedance: 50 Ohms (video impedance)Output voltage range: 0.5 ~ 3.5v (corresponding to -52 ~ + 8dbm)Input/output ratio: ~ 50mV/dBmInput dynamic range: -60 ~ +10dBm (high linear dynamic range: -52 ~ +8dBm)Power voltage: +3.3~5V.DC @20mA Weight: 8g Package includes: 1 x AD8362 Module
