HMC1126-EVALZ

HMC1126-EVALZ is a 4-layer printed circuit board (PCB). The substrate between the top layer and the first internal layer is 12 mils thick and is made from Rogers 4003C. The internal and bottom side layers are all ground planes. The RFIN and RFOUT ports on the HMC1126-EVALZ are populated with 1.85mm, female coaxial connectors, and the respective RF traces have a 50 ohm characteristic impedance. HMC1126-EVALZ is populated with components suitable for use over the entire -40 to 85°C operating temperature range of HMC1126ACEZ. To calibrate out board trace losses, a through calibration path, CAL, is provided between the CAL1 and CAL2 connectors. CAL1 and CAL2 must be populated with 1.85mm, female coaxial connectors. The power and bias voltages are the applied surface-mount technology (SMT) test points VDD, VGG1, and VGG2. Because there is no ground pin on the HMC1126-EVALZ, connect ground cable by attaching a clip lead to one of RF connector edges or to one of available holes in the PCB.
