ADL8130

• 4-layer, Rogers 4003C evaluation board
• End launch, 2.9mm RF connectors
• Through calibration path (depopulated connectors)

The ADL8130-EVALZ is a 4-layer printed circuit board (PCB) fabricated from 0.254mm (10mil) thick, Rogers 4003C, copper clad, forming a nominal thickness of 1.58mm (62mils). The ADL8130- EVALZ is designed to operate from 0.01GHz to 8GHz. The RFIN and RFOUT ports on the ADL8130-EVALZ are populated with 2.9mm, female coaxial connectors. The ADL8130-EVALZ is populated with components suitable for use over the entire −55°C to +125°C operating temperature range.

To calibrate out 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 5 and Table 1 in user guide for the through calibration path performance for the ADL8130-EVALZ.

Access the ADL8130-EVALZ ground and drain voltage through the surface-mount technology (SMT) test point connectors, GND and VDD. A supplementary test point for VRBIAS is included for simple access on the RBIAS pin (see Figure 6 and Figure 7 in user guide for the test point locations).

The RF traces on the ADL8130-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.

The power supply decoupling capacitors on the ADL8130-EVALZ represent the configuration used to characterize and qualify the device.
