C1, C2, C4, C11, C12, C15, C16,

C30, C31, L1, L2, R2, R3, P4

Power supply and ground decoupling. Nominal supply decoupling

consists of a 0.1 µF capacitor to ground.

C1, C2, C30 = 10 µF (Size 1210)

C4, C11, C12, C15, C16, C31 =

0.1 µF (Size 0402)

L1, L2 = 33 µH (Size 1812)

R2, R3 = 0 Ω (Size 0402)

P4 = installed

T1, T2, C3, C6, C7 to C10, R31,

R32, R43, R44, R45, R46, R47,

R48, R49, R50

Input interface. The INP1_SE, INM1, INP2_SE, and INM2 input SMAs

are used to drive the part differentially by bypassing the baluns.

Using only INP1_SE and INP2_SE in conjunction with the baluns

enables single-ended operation. The default configuration of the

evaluation board is for single-ended operation.

T1 and T2 are 8:1 impedance ratio baluns that transform a single-

ended signal in a 50 Ω system into a balanced differential signal in a

400 Ω system.

R31, R32, R47, R48, R49, and R50 are populated for appropriate

balun interface

T1, T2 = Pulse Electronics

C3, C6 = 0.1 µF (Size 0402)

C7 to C10 = 0.1 µF (Size 0602)

R31, R32, R47 to R50 = 0 Ω (Size

0402)

R43 to R46 = open (Size 0402)
