Analog Devices Inc. ADPA1105-EVALZ Evaluation Kit

Analog Devices Inc. ADPA1105-EVALZ Evaluation Kit facilitates an extensive evaluation of the ADPA1105 0.9GHz to 1.6GHz, GaN Power Amplifier. The ADPA1105-EVALZ consists of a 2-layer printed circuit board (PCB) fabricated from a 10mil thick, Rogers 4350B copper-clad mounted to an aluminum heat spreader. The heat spreader aids in both providing thermal relief to the device and mechanical support to the PCB.

The ADI ADPA1105-EVALZ Evaluation Kit ships with a drain pulsing board (Pulser board) that can be plugged into the headers and configured to control the biasing of the ADPA1105. This is allowed by providing a negative gate voltage and a control signal connecting and disconnecting the drain voltage to the ADPA1105-EVALZ Kit. The ADPA1105-EVALZ can also be operated alone in pulsed gate mode, where a negative pulse is applied to the ADPA1105 VGG1 and VGG2 pins.
