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 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 V_SET. The AD8317 provides 0 V to

(V_POS− 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,

V_OUT, 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 ꢀ, 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.

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.
