EVALUATION BOARD

Figure 47 shows the schematic of the AD8376 evaluation board.

The silkscreen and layout of the component and circuit sides

are shown in Figure 48 through Figure 51. The board is powered

by a single supply in the 4. 5 V to 5.5 V range. The power supply

is decoupled by 10 μF and 0.1 μF capacitors at each power supply

pin. Additional decoupling, in the form of a series resistor or

inductor at the supply pins, can also be added. Table 6 details

the various configuration options of the evaluation board.

The output pins of the AD8376 require supply biasing with

1 μH RF chokes. Both the input and output pins must be ac-

coupled. These pins are converted to single-ended with a pair of

baluns (Mini-Circuits® TC3-1T+ and M/A-COM ETC1-1-13).

The baluns at the input, T1 and T2, are used to transform 50 Ω

source impedances to the desired 150 Ω reference levels. The

output baluns, T3 and T4, and the matching components are

configured to provide 150 Ω to 50 Ω impedance transformations

with insertion losses of about 11 dB.
