High Frequency Devices Group

GDAF

The main R&D activities of the group are related to radiofrequency (RF) and microwave technologies. Specifically, they focus on linear/non-linear modelling and characterization of microwave active devices and circuits, the design of hybrid and monolithic microwave integrated circuits, and the design of RF circuits for radio communications.

Research topics

Linear and nonlinear modelling, and experimental characterization of microwave semiconductor active devices and MIC circuits, both wafer and encapsulated.
Design of hybrid and monolithic MIC circuits for microwave applications.
Large-signal measurement (vectorial calibrated) in radio frequency and microwaves, with monotone and multi-tone excitation in different terminal impedance environments (active and passive load-pull).
Design of radio frequency circuits for radio communications: power amplifiers, filters, combiners, duplexers, etc.
