We investigate the room-temperature bandwidth performance of AlInAsSb avalanche photodiodes under 2-μm illumination. Parameter characterization denotes RC-limited performance. While measurements indicate a maximum gain-bandwidth product of 44 GHz for a 60-μm-diameter device, we scale this performance to smaller device sizes based on the RC response. For a 15-μm-diameter device, we predict a maximum gain-bandwidth product of approximately 144 GHz based on the reported measurements.
