ADI AD8362ARUZ-REEL7

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. The AD8362 has a 1.3 mW power consumption when powered down by a logic high applied to the PWDN 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.
