WebJul 7, 2016 · The thermal conductivity of GaN, at 1.7 W/cm-K, is more than three times the thermal conductivity of GaAs, at 0.46 W/cm-K. High thermal conductivity translates into the lowest temperature rise at conduction, a characteristic that enables GaN devices to handle higher power levels than GaAs devices using the same device structure, such as a … WebMar 1, 1998 · We compare self-heating effects in AlGaN-GaN heterostructure field effect transistors (HFETs) grown on sapphire and SiC substrates. Heat dissipation strongly affects the device characteristics soon after the application of the source-drain voltage (in less than 10/sup -7/ s). Our results show that in HFET's with the total epilayer thickness less than …
WebAt X-band, power FETs often have 150 um wide gates. At Ka-band the the gate width is typically 75 micron maximum. At W-band perhaps 40 micron fingers is the upper limit. Gate width versus gate length A gate finger refers to a single gate structure. Gate periphery is the total size of a FET.
