ADL5330
EVALUATION BOARD
Figure 49 shows the schematic of the ADL5330 evaluation
board. The silkscreen and layout of the component and circuit
sides are shown in Figure 50 through Figure 53. The board is
powered by a single-supply in the 4.75 V to 5.25 V range. The
power supply is decoupled by 100 pF 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 5 details the various configuration options of the
evaluation board.
The output pins of the ADL5330 require supply biasing with
120 nH RF chokes. Both the input and output pins have 50 Ω
differential impedances and must be ac-coupled. These pins are
converted to single-ended with a pair of baluns (M/A-COM
part number ETC1-1-13).
Instead of using balun transformers, lumped-element baluns
comprising passive L and C components can be designed.
Alternate input and output RF paths with component pads are

available on the circuit side of the board. Components M1
through M9 are used for the input interface, and M10 through
M18 are used for the output interface. DC blocking capacitors
of 100 pF must be installed in C15 and C16 for the input and
C17 and C18 for the output. The C5, C6, C11, and C12
capacitors must be removed. An alternate set of SMA
connectors, INPUT2 and OUT2, are used for this
configuration.
The ADL5330 can be driven single-ended; use the RF input
path on the circuit side of the board. A set of 100 pF dc blocking
capacitors must be installed in C15 and C16. C5 and C6 must
be removed. Use the INPUT2 SMA to drive one of the
differential input pins. The unused pin should be terminated to
ground, as shown in Figure 34.
The ADL5330 is enabled by applying a logic high voltage to the
ENBL pin by placing a jumper across the SW1 header in the
O position. Remove the jumper for disable. This pulls the ENBL
pin to ground through the 10 kΩ resistor.
