EVAL-ADL9006

Product Details

The ADL9006-EVALZ consists of a 2-layer printed circuit board (PCB) fabricated from 10 mil thick, Rogers 4350, copper clad, mounted to an aluminum heat sink. The heat sink assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat sink allow attachment to larger heat sinks for improved thermal management. The RFIN and RFOUT ports on the ADL9006-EVALZ are populated with 2.9 mm, female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADL9006-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL9006. To calibrate out board trace losses, a through calibration path, THRU CAL, is provided between the J5 and J6 connectors. J5 and J6 must be populated with RF connectors to use the through calibration path. The power voltages, ground voltages, gate control voltages, and detector output voltages are accessed through two 4-pin headers.

The RF traces are 50 Ω, grounded, coplanar waveguide. The package ground leads and the exposed paddle directly connect to the ground plane. Multiple vias are used to 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 heat sink.

The power supply decoupling capacitors on the ADL9006-EVALZ represent the configuration used to characterize and qualify the device. It is possible to reduce the number of capacitors, but this reduction varies from system to system. It is recommended to first remove or combine the largest capacitors that are farthest from the ADL9006 when reducing the number of capacitors.
