Abstract :
In this work we report on the state-of-the-art combination at V-band between simultaneously power density (370 mW/mm), power-added efficiency (28.3%), and power gain (5.2 dB) of InP pseudomorphic HEMTs biased at a low drain voltage of 2 V. The performance of these double delta-doped pseudomorphic AlInAs-GaInAs HEMTs on InP with an original strain compensated channel was measured at 60 GHz. This demonstrates a good potentiality for low-voltage applications in order to reduce the power supply of systems
