Analog Devices Inc. ADPA7006-EVALZ Amplifier Evaluation Board

The RFIN and RFOUT ports on the ADPA7006-EVALZ are populated by 2.9mm, female coaxial connectors. The respective RF traces of the ports have a 50Ω characteristic impedance. The ADPA7006-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the device. RF traces are 50Ω grounded, coplanar waveguide. Package ground leads and the exposed paddle 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 heat sink.

The power supply decoupling capacitors on the ADPA7006-EVALZ represent the configuration used to characterize and qualify the device. It is possible to reduce the number of capacitors with a scope, but the scope varies from system to system. It is recommended to first remove or combine the largest capacitors that are farthest from the device.
