GENERAL DESCRIPTION
1 MHz to 8 GHz, 70 dB
FUNCTIONAL BLOCK DIAGRAM
Figure 1.
The AD8318-EP is a demodulating logarithmic amplifier,
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 <1.5 mW
when the device is disabled.
The AD8318-EP can be configured to provide a control voltage
to a VGA, such as a power amplifier or a measurement output,
from Pin VOUT. Because the output can be used for controller
applications, wideband noise is minimal.
In this mode, the setpoint control voltage is applied to VSET.
The feedback loop through an RF amplifier is closed via VOUT,
the output of which regulates the amplifier output to a magnitude
corresponding to VSET. The AD8318-EP provides 0 V to 4.9 V
output capability at the VOUT pin, suitable for controller
responsi bility is assumed by Analog Devices for its use, nor for any infringements of patents or other
rights of third parties that may result from its use. Specifications subject to change without notice. No
license is granted by implication or otherwise under any patent or patent rights of Analog Devices.
Figure 2. Typical Logarithmic Response and Error vs. Input Amplitud e at 5.8 GHz
applications. As a measurement device, Pin VOUT is externally
connected to VSET to produce an output voltage, V
OUT
is a decreasing linear-in-dB function of the RF input signal
amplitude.
The logarithmic slope is nominally −25 mV/dB but can be
adjusted by scaling the feedback voltage from VOUT to the
VSET interface. The intercept is 20 dBm (re: 50 Ω, CW input)
using the INHI input. These parameters are very stable against
supply and temperature variations.
The AD8318-EP is fabricated on a SiGe bipolar IC process and
is available in a 4 mm × 4 mm, 16-lead LFCSP. Performance is
specified over a temperature range of –55
o
C to +105oC.
Additional application and technical information can be found
in the AD8318 data sheet.
