PERFORMING EVALUATION

ADMV8913-EVALZ QUICK START

To set up the ADMV8913-EVALZ, take the following steps:
1. Connect the RF1 and RF2 ports to a network analyzer (or a
similar instrument). Typically, RF1 and RF2 are connected
to Port 1 and Port 2 on the network analyzer, as shown in
Figure 2.
2. Connect the
ADMV8913-EVALZ. Do not connect the SDP-S to the PC
until after completing Step 4 or Step 5.
3. On the ADMV8913-EVALZ, slide the S2 switch down (as
shown in Figure 2) to select the SPI.
4. On the ADMV8913-EVALZ, slide the S1 switch down (as
shown in Figure 2) to power the ADMV8913-EVALZ from
the 5 V USB supply voltage from the PC via the SDP-S.
5. Alternatively (to Step 3), slide the S1 switch up and connect
power supplies to the VPOS and VNEG ports. The applicable
voltage range for VPOS is between 3.5 V and 5.5 V, and the
applicable voltage range for VNEG is between −5.5 V and
−2.7 V. The external supply current limits must be set to
20 mA. The expected supply current drawn for VPOS is
12 mA to 14 mA, and for The expected supply current
draw for VNEG is 2 mA to 3 mA. The
current drawn per supply pin is typically 10s of microamps
or less. Most of the current drawn from the ADMV8913-
EVALZ comes from the LDO regulators and the status
indicator light emitting diodes (LEDs), DS1 to DS3.
6. Connect a USB cable between the PC and the SDP-S.
7. Open the ACE
in the Attached Hardware section of the Start tab. Double
click the ADMV8913 Board plug-in to open two tabs, one
for the ADMV8913 Board plug-in view and one for the
ADMV8913 chip plug-in.
Use the CONFIGURATION section (see Figure 9) in the
8.
ACE software to initialize the chip. By default, the
ADMV8913_Register_Load_1.csv file is loaded into this
section. Click Apply to send the default settings to the chip
and to allow the main diagram user controls to become
editable.

NETWORK ANALYZER SETTINGS

When evaluating the ADMV8913-EVALZ, a good starting point
for configuring the network analyzer is as follows:
• Start frequency = 0.1 GHz
• Stop frequency = 40 GHz
• Number of points = 400
• Step size = 100 MHz
•
Power level = −10 dBm
•
Measure types = S-parameters (S21, S11, and S22)
• Format = log magnitude
• Calibration = full 2-port
