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.
