Features and Benefits
The ADL8106-EVALZ is a 4-layer printed circuit board (PCB). The substrate between the top layer and the first internal layer is made from Rogers 4003C. The internal and bottom side layers are all ground.
The RFIN and RFOUT ports on the ADL8106-EVALZ are populated with 1.85 mm, female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADL8106-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL8106.
To calibrate out board trace losses, a through calibration path is provided between the CAL1 and CAL2 connectors. CAL1 and CAL2 must be populated with 1.85 mm, female coaxial connectors (for part number see Table 2). The power and bias voltages are applied to the surface-mounted technology (SMT) test points, VDD1, VDD2, and VGG.
The RF traces are 50 Ω, grounded, coplanar waveguide. The package ground leads and the exposed pad directly connect to the ground plane. Multiple vias are used to connect the ground planes with particular focus on the area directly beneath the ground pad. For full details on the ADL8106, see the ADL8106 data sheet, which must be consulted in conjunction with this user guide when using the ADL8106-EVALZ.
