ADL8201

• 4-layer, Rogers RO4003C and Isola 370HR evaluation board
• End launch, 2.92mm RF connectors
• Through calibration path (depopulated)

The ADL8201-EVALZ is a 4-layer printed circuit board (PCB) fabricated from 12mil thick, Rogers 4003C and Isola 370HR, copper clad, forming a nominal thickness of 62mils. The RFIN and RFOUT ports on the ADL8201-EVALZ are populated with 2.92mm, female coaxial connectors, and the corresponding RF traces have a 50Ω characteristic impedance. The ADL8201-EVALZ is populated with components suitable for use over the entire −55°C to +125°C operating temperature range of the ADL8201. To calibrate board trace losses, a through calibration path is provided between the J1 and J2 connectors. J1 and J2 must be populated with RF connectors to use the through calibration path. Refer to Figure 6 and Table 1 in the User Guide for the through calibration path performance.

The RF traces on the ADL8201-EVALZ are 50Ω grounded, coplanar waveguide. 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.

For full details on the ADL8201, see the ADL8201 data sheet, which must be consulted in conjunction with this user guide when using the ADL8201-EVALZ.
