ADL8113

• 4-layer, Rogers 4350B and Isola 370HR evaluation board
• End launch, 2.92mm RF connectors
• Through calibration path (depopulated)

The ADL8113-EVALZ consist of a 4-layer printed circuit board (PCB) fabricated from 0.254mm (10mil) thick, Rogers 4350B and Isola 370HR, copper clad, forming a nominal thickness of 1.60mm (63mils). The RFIN and RFOUT ports on the ADL8113-EVALZ are populated with 2.92mm, female coaxial connectors. The ADL8113- EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL8113. To calibrate board trace losses, two through calibration paths are provided. Install RF connectors in the J5, J6, J11, and J12 positions to use the through calibration paths. Refer to Table 1 in user guide for the through calibration RF path performance.

Access the ADL8113-EVALZ power supply and digital control pins through the surface-mount technology (SMT) test point connectors, VDD PA, VBIAS, GND, VDD_SW, VSS, VA, and VB.

The RF traces on the ADL8113-EVALZ are 50Ω, grounded, coplanar waveguides. The package ground leads and the exposed pad connect directly to the ground plane. Multiple vias connect the top and bottom ground planes with particular focus on the area directly beneath the ground paddle to provide adequate electrical conduction and thermal conduction to the ADL8113-EVALZ.

Figure 5 in user guide shows the ADL8113-EVALZ schematic and configuration used to characterize and qualify the device.
