Ib HEMT, zoo ib yam li lwm yam kev cuam tshuam hauv teb chaws, ua haujlwm ntawm txoj cai ntawm kev hloov pauv ntawm tus nqi hauv cov channel los ntawm lub rooj vag hluav taws xob, nrog rau kev txav mus los hauv cov channel tau tas li. … modulating tus cab kuj mus rau hauv lub channel los ntawm lub rooj vag voltage, ua kom tag nrho cov nqi nyob rau hauv lub channel.
HEMT siv rau dab tsi?
HEMTs yog siv rau hauv cov ntawv thov uas microwave millimeter yoj kev sib txuas lus tau ua. Lawv kuj siv rau radar, duab, thiab xov tooj cua astronomy. Yeej, HEMTs yog siv qhov kev nce siab ntawm cov zaus siab yuav tsum tau nrog rau cov suab nrov qis. Lawv kuj tau siv rau hauv cov ntawv thov hloov hluav taws xob.
HEMT txawv ntawm cov transistors li cas?
HEMT transistors yog tuaj yeem ua haujlwm ntawm ntau zaus dua li cov transistors zoo tib yam, mus txog millimeter yoj zaus, thiab siv rau hauv cov khoom siv siab xws li xov tooj ntawm tes, satellite TV receivers, voltage converters, thiab radar khoom.
qhov txawv ntawm mosfet thiab HEMT yog dab tsi?
High-mobility transistor electrons (hemt), tseem hu ua heterostructure fet (hfet) lossis modulation-doped fet (modfet), yog thaj chaw cuam tshuam cov transistors uas sib txuas ntawm ob cov khoom sib txawv nrog bandgap (ie heteroin). channel tsis yog thaj chaw doped (raws li yog ib qho rau MOSFETs).
Phemt transistor yog dab tsi?
pHEMT: Cov PHEMTs tau txais nws lub npe vim nws yogPseudomorphic Siab Electron Mobility Transistor. Cov cuab yeej no tau siv dav hauv kev sib txuas lus wireless thiab LNA daim ntawv thov. PHEMT transistors muab lub zog siab ntxiv ua haujlwm ua ke nrog cov suab nrov qis thiab kev ua haujlwm zoo.
