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). 20986-001 The ADMV8416-EVALZ/ADMV8432-EVALZ 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. Figure 1. ADMV8416-EVALZ Primary Side 20986-001 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. Figure 2.

A THRU CAL trace is available on the evaluation boards by means of installing end launch connectors onto J1 and J2. 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. 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 bandpass 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. The circuit board used in the application uses RF circuit design techniques. Signal lines must have 50 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-EVALZ evaluation boards are available from Analog Devices, Inc., upon request.
