ADPA7009-2-EVALZ

ADPA7009-2-EVALZ is a 2-layer Rogers 4350B evaluation board with heat spreader. It consists of a 2-layer PCB fabricated from 10 mil thick Rogers 4350B copper clad mounted to an aluminium heat spreader. The heat spreader assists in providing thermal relief to the ADPA7009-2 as well as mechanical support to the PCB. Mounting holes on the heat spreader allow it to be attached to larger heat sinks for improved thermal management. The RFIN and RFOUT ports are populated by 1.84mm female coaxial connectors, and their respective RF traces are of 50 ohm characteristic impedance. RF traces are 50 ohm grounded coplanar waveguide. Package ground leads and the exposed pad connect directly 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 spreader.
