This webinar presents the characterization of a short gate-length (0.15 μm), gallium nitride (GaN) on silicon carbide (SiC) process for millimeter-wave (mmWave) applications up to 40 GHz. The transistor characterization utilizes multiple techniques, including pulsed IV and small-signal S-parameters and EM simulation to extract frequency-dependent parasitics and nonlinear behavior along with load-pull measurements for model validation. In addition, a comprehensive study of the thermal device behavior was conducted using transient simulation to generate an electrothermal model. The models developed by United Monolithic Semiconductors (UMS) have been organized into the UMS GH15 process design kit (PDK) for the AWR Design Environment platform and the Microwave Office circuit simulator to support the development of monolithic microwave integrated circuits (MMICs) targeting mmWave telecommunications. This webinar will present several design examples using the GH15 PDK, including a 10 W Ka-band (29.5 – 36 GHz) PA and a 2 W integrated front end for 24 – 30 GHz combining a GH15 power amplifier (PA) with other gallium arsenide (GaAs) functions in a plastic package for 5G applications.
