1 CMPA2735075D 75 w, 2.7 - 3.5 ghz, gan mmic, power amplifer crees CMPA2735075D is a gallium nitride (gan) high electron mobility transistor (hemt) based monolithic microwave integrated circuit (mmic). gan has superior properties compared to silicon or gallium arsenide, including higher breakdown voltage, higher saturated electron drift velocity and higher thermal conductivity. gan hemts also offer greater power density and wider bandwidths compared to si and gaas transistors. this mmic contains a two-stage reactively matched amplifer design approach enabling very wide bandwidths to be achieved. rev 1.1 C april 2012 typical performance over 2.7-3.5 ghz (t c = 25?c) parameter 2.7 ghz 2.9 ghz 3.1 ghz 3.3 ghz 3.5 ghz units small signal gain 28 30 30 29 28 db saturated output power, p sat 1 67 85 101 103 94 w power gain @ p sat 1 22 24 25 25 24 db pae @ p sat 1 48 59 61 61 61 % note 1 : p sat is defned as the rf output power where the device starts to draw positive gate current in the range of 2-8 ma. features ? 28 db small signal gain ? 80 w typical p sat ? operation up to 28 v ? high breakdown voltage ? high temperature operation ? size 0.197 x 0.174 x 0.004 inches applications ? civil and military pulsed radar amplifers subject to change without notice. www.cree.com/wireless
