GENERAL DESCRIPTION
The AD8317 is a demodulating logarithmic amplifier, capable
of accurately converting an RF input signal to a corresponding
decibel-scaled output. It employs the progressive compression
technique over a cascaded amplifier chain, each stage of which
is equipped with a detector cell. The device can be used in either
measurement or controller modes. The AD8317 maintains
accurate log conformance for signals of 1 MHz to 8 GHz and
provides useful operation to 10 GHz. The input dynamic range
is typically 55 dB (re: 50 Ω) with less than ±3 dB error. The
AD8317 has 6 ns/10 ns response time (fall time/rise time) that
enables RF burst detection to a pulse rate of beyond 50 MHz.
The device provides unprecedented logarithmic intercept stability
vs. ambient temperature conditions. A supply of 3.0 V to 5.5 V
is required to power the device. Current consumption is typically
22 mA, and it decreases to 200 μA when the device is disabled.
The AD8317 can be configured to provide a control voltage to a
power amplifier or a measurement output from the VOUT pin.
Because the output can be used for controller applications, special
attention has been paid to minimize wideband noise. In this
mode, the setpoint control voltage is applied to the VSET pin.
The feedback loop through an RF amplifier is closed via VOUT,
the output of which regulates the output of the amplifier to a
magnitude corresponding to VSET. The AD8317 provides 0 V to
(VPOS 0.1 V) output capability at the VOUT pin, suitable for
controller applications. As a measurement device, VOUT is
externally connected to VSET to produce an output voltage,
VOUT, that is a decreasing linear-in-dB function of the RF input
signal amplitude.
The logarithmic slope is 22 mV/dB, determined by the VSET
interface. The intercept is 15 dBm (re: 50 Ω, CW input) using
the INHI input. These parameters are very stable against supply
and temperature variations.
The AD8317 is fabricated on a SiGe bipolar IC process and is
available in a 2 mm × 3 mm, 8-lead LFCSP with an operating
temperature range of 40°C to +85°C.
