ADL5391 Rev. 0 | Page 14 of 16 Table 4. Evaluation Board Configuration Options 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 C1, C5, C6, C9, C13, C15, C16, C19 Not installed, dc block capacitors. Open, 0402 capacitors R9, R10, R14, R15, R18 Snubbing resistors. 0 Ω, 0402 resistors R19, R20 Snubbing resistors. 0 Ω, 0603 resistors R7, R13, R16, R17 Snubbing resistors. Open, 0402 resistors C10 Filter capacitor. 100 pF, 0402 capacitor C12 Filter capacitor. 0.1 μF, 0402 capacitor C3 Filter capacitor. 0.1 μF, 0603 capacitor C11 Filter capacitor. 4.7 μF, 3216 capacitor 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 resistor.s 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 SW1 Enable switch: enable = 5 V, disable = 0 V. SW1 installed TP1, TP2, TP4, TP5, TP6, TP7, TP8, TP9 Green test loop. WP_DC, WM_DC, ZM_DC, ZP_DC, YP_DC, YM_DC, XP_DC, XM_DC TP13 Red test loop. VPOS TP12, TP14 Black test loops. COMM TP3, TP10, TP11 Yellow test loops. GADJ_DC, ENBL_DC, VMID DUT ADL5391. ADL5391ACPZ |
