GENERAL DESCRIPTION
The ADMV8416-EVALZ/ADMV8432-EVA L Z evaluation boards
aid in the evaluation of the ADMV8416 and ADMV8432 band-
pass filters with selectable pass band frequency.
The ADMV8416-EVALZ/ADMV8432-E VA L Z evaluation
boards have end launch 2.4 mm connectors on both the input
and the output to allow an efficient connection to test
equipment and other circuitry.
Optimized power and ground planes ensure low noise and high
speed operation. Component placement and power supply
bypassing are optimized for maximum circuit flexibility and
performance.
All components are placed on the primary side. No components
are placed on the secondary side (see Figure 1 and Figure 2).
Note that the ADMV8432-EVALZ evaluation board is labeled
ADMV8416-EVALZ. The ADMV8416 and ADMV8432 are
evaluated using the same printed circuit board (PCB).
The ADMV8416 and ADMV8432 data sheets, available at
www.analog.com, provide full specifications for the
ADMV8416 and ADMV8432. Consult the ADMV8416 and
ADMV8432 data sheets in conjunction with this user guide
when using the evaluation boards.

EVALUATION BOARD HARDWARE
RF CONNECTIONS
The RF input and output of the ADMV8416 and ADMV8432
are accessible by connecting to the J3 and J4. A THRU CAL
trace is available on the evaluation boards by means of installing
end launch connectors onto J1 and J2.
POWER SUPPLY SETUP
Connect a power supply to VDD and set the voltage to 5V.
Connect a power supply to VEE and set the voltage to −5 V.
Both VDD and VEE draw minimal current within the
microampere range.
FILTER CONTROL
The VCTL pin allows users to select either the low band or high
band portion of the device. Connect a power supply to the
VCTL pin and set the voltage to 0 V to select the high band-
pass filter or set the voltage to 2.5 V to select the low band-pass
filter. The center frequency is adjustable by supplying the
VTUNE voltage, which varies from 0 V to 15 V.
EVALUATION BOARD STACKUP
All RF traces are routed on Layer 1 (primary side), and all other
layers are ground planes that provide a solid ground for RF
transmission lines, as shown in Figure 3. The top dielectric
material is Rogers 4350, offering low loss performance. The
prepreg material in Layer 2 attaches the core layers together,
which includes a 370HR laminate with copper traces above and
below. Both the prepreg material and the Isola 370HR core layer
are used to achieve the required board finish thickness.
The circuit board used in the application uses RF circuit design
techniques. Signal lines must have 50 Ω impedance while the
package ground leads and exposed pad must be connected directly
to the ground plane (see Figure 3). Use a sufficient number of
via holes to connect the top and bottom ground planes. The
ADMV8416-EVALZ/ADMV8432-EVA L Z evaluation boards are
available from Analog Devices, Inc., upon request.
