capable of accurately converting an RF input signal to a
corresponding decibel-scaled output voltage. It employs the
progressive compression technique over a cascaded amplifier
chain, each stage of which is equipped with a detector cell.
The device is used in measurement or controller mode. The
AD8318-EP maintains accurate log conformance for signals of
1 MHz to 6 GHz and provides useful operation to 8 GHz. The
input range is typically 60 dB (re: 50 Ω) with error less than
±1 dB. The AD8318-EP has a 10 ns response time that enables
RF burst detection to beyond 45 MHz. The device provides
unprecedented logarithmic intercept stability vs. ambient
temperature conditions. A 2 mV/°C slope temperature sensor
output is also provided for additional system monitoring.
A single supply of 5 V is required. Current consumption is
typically 68 mA. Power consumption decreases to …
