25 / 28 page ![]() ADL5811 Rev. 0 | Page 25 of 28 EVALUATION BOARD An evaluation board is available for the ADL5811. The standard evaluation board schematic is presented in Figure 61. The USB interface circuitry schematic is presented in Figure 64. The evaluation board layout is shown in Figure 62 and Figure 63. The evaluation board is fabricated using Rogers® 3003 material. Table 12 details the configuration for the mixer characterization. The evaluation board software is available on www.analog.com.

Evaluation Board Schematic Table 12. Evaluation Board Configuration Components Description Default Conditions C1, C2, C8, C18, C19, C20, C23 Power supply decoupling. Nominal supply decoupling consists of a 0.1 μF capacitor to ground in parallel with a 10 pF capacitor to ground positioned as close to the device as possible. C1, C2 = 0.1 μF (size 0402), C8, C18, C19, C20, C23 = 10 pF (size 0402) C6, C7, RFIN RF input interface. The input channel is ac-coupled through C6. C7 provides bypassing for the center tap of the RF input balun. C6 = 22 pF (size 0402), C7 = 100 pF (size 0402) C3, C4, C5, L1, L2, R20, R21, T1, IFOP, IFON IF output interface. The open-collector IF output interfaces are biased through pull-up choke inductors, L1 and L2. T1 is a 4:1 impedance transformer used to provide a single-ended IF output interface, with C5 providing center-tap bypassing. Remove R21 for balanced output operation. C3, C4, C5 = 120 pF (size 0402), L1, L2 = 470 nH (size 0603), R20 = open, R21 = 0 Ω (size 0402), T1 = TC4-1W+ (Mini-Circuits®) C17, LOIP LO interface. C17 provides ac coupling for the LOIP local oscillator input. C17 = 22 pF (size 0402) R1 Bias control. R1 sets the bias point for the internal IF amplifier. R1 = 910 Ω (size 0402) |
