GENERAL DESCRIPTION
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.
