Features and Benefits
- 4-layer, Rogers 4003C evaluation board
- End launch, 1.85 mm RF connectors
- Through calibration path (depopulated)
The 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 1.85 mm, female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The HMC1126-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the 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 1.85 mm, female coaxial connectors (see Table 2 in th user guide for the part number). 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 the ground cable by attaching a clip lead to one of the RF connector edges or to one of the available holes in the PCB.
The RF traces are 50 Ω, grounded, coplanar waveguide. The package ground leads and the exposed pad connect directly to the ground plane. Multiple vias connect the ground planes with particular focus on the area directly beneath the ground pad.
For full details on the HMC1126ACEZ, see the HMC1126ACEZ data sheet, which must be consulted in conjunction with the user guide when using the HMC1126-EVALZ.
