Evaluation Board
Figure 16 shows the schematic of the AD8367 evaluation board.
The board is powered by a single supply of 2.7 V to 5.5 V. Table
IV details the various configuration options of the evaluation board.

Characterization Setup and Methods
Minimum-loss L-pad matching networks were used to interface
standard 50
test equipment to the 200
input impedance during
the characterization process. Using a 57.6
shunt resistor followed
by a 174
series resistor provides a broadband match between the
50
test equipment and the 200
device impedance as illustrated
in Figure 19. The insertion loss of this network is 11.5 dB.
