Ensure that signal lines have 50 Ω impedance when C2 the package ground leads are connected directly to the ground 100pFSMAC3RFOUT plane (see Figure 14). Use a sufficient number of via holes to 1000pFJ256 connect the top and bottom ground planes. VCCOUT The evaluation board has two connectors, as shown in Figure 14. U1HMC434 The RF input connector (J1) and the RF output connector (J2) are PCB mount SMA connectors. INGND32SMA The evaluation board is powered from a single 3 V supply; RFINJ1 013 GNDC1 connect this supply using the J3 (VCC) and J4 (GND) test points.
