Component

Function

Part Number

Default Value

J1, J5, J6, J8

SMA connectors for single-ended, high frequency operation. If J5

and J6 are used, R9, R10, R14, and R15 should be removed. R2 and

R3 should also be populated to match the inputs. If used in broadband

operation, C4, C7, C8, and C2 need to be replaced with 0 Ω resistors.

WP, ZP, YP, XP

J2, J4, J7, J9

SMA connectors for broadband differential operation. If these are

used, baluns should be removed and jumped over using 0 Ω

resistors, and C14, C15, C18, and C20 should be removed.

WM, ZM, YM, XM

J3

SMA connector for connection to GADJ.

GADJ

T1, T2, T3, T4

Single-ended-to-differential transformation for high frequency ac

operation. If dc operation is necessary, the baluns can be removed

and jumped over using 0 Ω resistors.

TC1-1-13M+

Mini-Circuits

T3 and T4 are populated,

but the Y and Z inputs

are set up for dc operation.

C2, C4, C7, C8, C14,

C17, C18, C20

DC block capacitors.

0.1 µF, 0402 capacitors

R1

Matching resistor.

56.2 Ω, 0603 resistor

R2, R3, R12

Matching resistors. Input impedance to X, Y, and Z inputs are the

same. For the same frequency, R1, R2, and R3 should be the same.

Open, 0603 resistors

R5, R6

Matching resistors.

24.9 Ω, 0402 resistors

R4

Matching resistor.

100 Ω, 0603 resistor

R8, R11

Can be used for voltage divider or filtering.

Open, 0603 resistors
