EVALUATION BOARD

Table 5. Evaluation Board (Rev. A) Configuration Options

Component

Function

Default Conditions

Supply and Ground Connections.

Not applicable

Input Interface.

R1 = 52.3 Ω (Size 0402)

C1 = 47 nF (Size 0402)

C2 = 47 nF (Size 0402)

The 52.3 Ω resistor in Position R1 combines with the internal input impedance

of the AD8317 to give a broadband input impedance of about 50 Ω. C1 and C2

are dc-blocking capacitors. A reactive impedance match can be implemented

by replacing R1 with an inductor and C1 and C2 with appropriately valued

capacitors.

R5, R7

Temperature Compensation Interface.

R5 = 200 Ω (Size 0402)

R7 = open (Size 0402)

The internal temperature compensation network is optimized for input signals

up to 3.6 GHz when R7 is 10 kΩ. This circuit can be adjusted to optimize

performance for other input frequencies by changing the value of the resistor

in Position R7. See Table 4 for specific R_TADJresistor values.

R2, R3, R4, R6, RL, CL

Output Interface—Measurement Mode.

R2 = 0 Ω (Size 0402)

In measurement mode, a portion of the output voltage is fed back to the VSET

pin via R2. The magnitude of the slope of the VOUT output voltage response

can be increased by reducing the portion of V_OUTthat is fed back to VSET. R6

can be used as a back-terminating resistor or as part of a single-pole, low-pass

filter.

R3 = open (Size 0402)

R4 = open (Size 0402)

R6 = 1 kΩ (Size 0402)

RL = CL = open (Size 0402)

R2, R3

Output Interface—Controller Mode.

R2 = open (Size 0402)

In this mode, R2 must be open. In controller mode, the AD8317 can control the R3 = open (Size 0402)

gain of an external component. A setpoint voltage is applied to Pin VSET, the

value of which corresponds to the desired RF input signal level applied to the

AD8317 RF input. A sample of the RF output signal from this variable gain

component is selected, typically via a directional coupler, and applied to the

AD8317 RF input. The voltage at the VOUT pin is applied to the gain control of

the variable gain element. A control voltage is applied to the VSET pin. The

magnitude of the control voltage can optionally be attenuated via the voltage

divider comprising R2 and R3, or a capacitor can be installed in Position R3 to

form a low-pass filter along with R2.

C4, C5

Power Supply Decoupling.

C4 = 0.1 ꢀF (Size 0603)

C5 = 100 pF (Size 0402)

The nominal supply decoupling consists of a 100 pF filter capacitor placed

physically close to the AD8317 and a 0.1 ꢀF capacitor placed nearer to the

power supply input pin.

Filter Capacitor.

C3 = 8.2 pF (Size 0402)

The low-pass corner frequency of the circuit that drives the VOUT pin can be

lowered by placing a capacitor between CLPF and ground. Increasing this

capacitor increases the overall rise/fall time of the AD8317 for pulsed input

signals. See the Output Filtering section for more details.
