Components Function Default Conditions
C1, C13 to C16, R3 to R6
Power supply decoupling. Nominal supply decoupling consists of a
0.1 μF capacitor to ground followed by 0.01 μF capacitors to ground
positioned as close to the device as possible.
C1 = 0.1 μF (size 0603),
C13 to C16 = 0.01 μF (size 0402),
R3 to R6 = 0 Ω (size 0603)
T1, T2, C5, C18, C20, C21,
R12 to R21, R44 to R48,
R50, R54, R58, R62, R63
Input interface. The default configuration of the evaluation board is
for single-ended operation. T1 and T2 are 4:1 impedance ratio baluns to
transform a 50 Ω single-ended input into a 200 Ω balanced differential
signal. R12 to R14 and R15, R16, and R19 are populated for appropriate
balun interface. R44 to R48 and R50, R54, R58, R62, and R63 are
provided for generic placement of matching components. C5, C18,
C20, and C21 are balun decoupling capacitors. R17, R18, R20, and
R21 can be populated with 0 Ω, and the balun interfacing resistors
can be removed to bypass T1 and T2 for differential interfacing.
T1, T2 = ADT4-6T+ (Mini-Circuits),
C5, C20 = 0.1 μF (size 0402),
C18, C21 = do not install,
R12 to R16, R19, R44 to R47 = 0 Ω
(size 0402),
R17, R18, R20, R21,R48, R50, R54,
R58, R62, and R63 = open (size 0402)
T3, T4, C24 to C27, R29 to
R31, R33 to R39, R65, R67
to R74, R80
Output interface. The default configuration of the evaluation board
is for single-ended operation. T3 and T4 are 4:1 impedance ratio
baluns to transform a 50 Ω single-ended output into a 200 Ω balanced
differential load. R29 to R31, R33, R38, and R39 are populated for
appropriate balun interface. R65, R67 to R74, and R80 are provided
for generic placement of matching components. C24, C25, C26, and
C27 are balun decoupling capacitors. R34 to R37 can be populated
with 0 Ω, and the balun interfacing resistors can be removed to
bypass T3 and T4 for differential interfacing.
T3, T4 = ADT4-6T+ (Mini-Circuits),
C24, C25 = 0.1 μF (size 0402),
C26, C27 = do not install,
R29 to R31, R33, R38, R39, R65, R67,
R68, R80 = 0 Ω (size 0402),
R34 to R37, R69 to R74 = open (size 0402)
