GENERAL DESCRIPTION
The AD8363 is a true RMS responding power detector that has
more than 50 dB measurement range when driven with a
single-ended 50 Ω source. The device provides a solution in a
variety of high frequency communication systems, and in
instrumentation, requiring an accurate response to signal
power. The AD8363 is easy to use with its single-ended 50 Ω
input, only requiring a single 5 V supply, and a few capacitors.
The AD8363 can operate from arbitrarily low frequencies to 6
GHz and can accept inputs that have RMS values from less than
-50 dBm to at least 0 dBm, with large crest factors, exceeding
the requirements for accurate measurement of WiMAX,
WCDMA, and CDMA signals.
Used as a power measurement device, VOUT is connected to
VSET. The output is then proportional to the logarithm of the
RMS value of the input. In other words, the reading is
presented directly in decibels and is conveniently scaled 1 V per
decade, or 50 mV/dB; other slopes are easily arranged. In
controller mode, the voltage applied to VSET determines the
power level required at the input to null the deviation from the
set point. The output buffer can provide high load currents.
The AD8363 has 1.5 mW power consumption when powered
down by a logic high applied to pin 1, TCM2. It powers up
within about 30 μs to its nominal operating current of 60 mA at
25°C. The AD8363 is supplied in a 4 mm x 4 mm, 16-lead
LFCSP for operation over the temperature range of −40°C to
+125°C. An evaluation board is available.
The AD8363 can determine the true power of a high frequency
signal having a complex low frequency modulation envelope, or
can be used as a simple low frequency RMS voltmeter. The
high-pass corner generated by its internal offset-nulling loop
can be lowered by a capacitor added on the CHPF pin.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Output pin in Measurement Mode (error Amplifier output). In measurement mode,
normally connected directly to VSET. This pin can be used to drive a gain control when

Function/Notes
Default Value
C6, C10, C11,
C12
Input:
C10=0.1uF, C12=0.1uF,
C6=Open, C11=Open
The AD8363 was designed to be driven single ended. At frequencies below 2.6 GHz, more
dynamic range can be achieved by driving Pin 14 (INHI). In order to do this, C10 and C12
should be populated with an appropriate valued capacitor for the frequency of operation. C6
and C11 should be left open. For frequencies above 2.6 GHz, greater dynamic range can be
achieved by Driving Pin 15 (INLO). This can be done by using an appropriate valued capacitor
for C6 and C11, while leaving C10 and C12 open.
R7, R10, R11
VTGT:
R10=845Ω, R11= 1.4KΩ
R10 and R11 are set up to provide 1.4V to VTGT from VREF. An external voltage can be used if
R10 and R11 are removed.
C4, C5, C7, C13,
R14, R16
Power Supply Decoupling:
C4=100 pF, C5=100 pF,
C7= 0.1uF, C13= 0.1uF,
R14= 0 Ω, R16= 0 Ω
The nominal supply decoupling consists of a 100 pF filter capacitor placed physically close to
the AD8363, a 0 Ω series resistor, and a 0.1 uF capacitor placed closer to the power supply
input pin. The 0 Ω resistor can be replaced with a larger value resistor to add more filtering, at
the expense of a voltage drop.
R1, R2, R6, R13,
R15
Output Interface--Measurement Mode:
R1=0 Ω, R2=Open,
R6=0 Ω, R13 = Open ,
R15 = 0 Ω
In measurement mode, a portion of the output voltage is fed back to the VSET pin via R6. The
magnitude of the slope at VOUT can be increased by reducing the portion of VOUT that is fed
back to VSET, using a voltage divider created by R6 and R2 . If a fast responding output is
expected, the 0 Ω resistor on R15 can be removed to reduce parasitics on the output.
Output Interface--Controller Mode:
In this mode, R6 must be open and R13 must have a 0 Ω resistor. In controller mode, the
AD8363 can control the gain of an external component. A setpoint voltage is applied to the
VSET pin, the value of which corresponds to the desired RF input signal level applied to the
AD8363 RF input. If a fast responding output is expected, the 0 Ω resistor on R15 can be
removed to reduce parasitics on the output.
C9, C8, R5
C3
Low-pass filter capacitors:
C8=Open, C9=0.1uF,
R5=0 Ω
The low-pass filter capacitors reduce the noise on the output and affect the pulse response
time of the AD8363. The smallest CLPF capacitance should be 400 pF
CHPF capacitor
C3= 2700 pF
The CHPF capacitor introduces a high-pass filter effect into the AD8363 transfer function and
can affect the response time. It should be tied to VPOS.
R9, R12
R17, R18
Paddle
TCM2/PWDN:
R9= Open, R12= Open
The TCM2/PWDN pin controls the amount of nonlinear intercept temperature compensation
and/or shuts down the device. The evaluation board is configured to control this from a test
loop but VREF can be used through a voltage divider created from R9 and R12.
TCM1:
R17=Open, R18=Open
TCM1 controls the intercept temperature compensation (3K impedance). The evaluation board
is configured to control this from a test loop but VREF can be used through a voltage divider
created from R17 and R18
The paddle should be tied to both a thermal and electrical ground
