GaInP material has high breakdown electric fields, and thus is suitable for a¨alanche transit-time de¨ice application. Millimeter-( ) wa¨e GaInP IMPATT de¨ices at operating temperature 500 K are analyzed by a large-signal model in this letter. The simulation confirms that a GaInP IMPATT de¨ice has a

✦ Synopsis
SiC IMPATT de¨ices ha¨e an efficiency and power ad¨antage o¨er Si and GaAs IMPATT de¨ices at millimeter-wa¨e frequencies. A lucky drift model describing ionization rates as a function of electric fields at high temperatures has been incorporated into a Read-type ( large-signal model. The simulation demonstrates that the efficiency and ) ( ) q dc power density at operating temperature 800 K for SiC p n single-( 2 ) drift flat-profile IMPATT structures is 12.4% 6.7 MWrcm , 15% ( 2 ) ( 2 ) 4.5 MWrcm , and 15.8% 3.3 MWrcm for frequencies of 200, 100, and 50 GHz, respecti¨ely.
