Dab tsi yog qhov kev siv ntawm diodes nyob rau hauv cov khoom sib txuas lus?

1, Kev faib cov khoom siv ntawm Diode hauv cov khoom siv sib txuas lus
Kev siv ntawm diodes nyob rau hauv kev sib txuas lus cov khoom sib txawv ho ntaus ntawv, kev ua haujlwm nyuaj, thiab thev naus laus zis los sib txawv. Noj cov xwm txheej raug ua piv txwv:
5G Chaw Nres Tsheb: Ib qho chaw nres tsheb ib zaug li Ntawm lawv, RF diodes (xws li schottky diodes thiab varvor diodes) tus account rau ntau dua 40% thiab siv rau ntau zaus kev sib xyaw, thiab ntau zaus synthesis; Nyob rau hauv lub hwj chim module, muaj kwv yees li 1500 txoj kev nrawm nrawm Tsis tas li ntawd, TVs diodes yog siv rau kev tiv thaiv chaw nres nkoj, nrog ib lub chaw nres tsheb ib zaug ntawm 300 daim.
Satellite cov khoom sib txuas lus: ib qho kev sib txuas lus ib zaug ntawm lub siab qis dua los ntawm 100000 tus txiv neej ua haujlwm nyob rau hauv lub parametric amplifier yog qhov tseem tivthaiv. Kev siv ntawm ib lub cuab yeej ib qho ntau tshaj 5000, thiab qis - lub suab nrov teeb tsa los ntawm cov nyhuv refinific; Meanwhile, qhov chaw da dej amplifiers tau siv rau high - zaus} zaus ntawm kev siv kwv yees li 2000 chav nyob rau ib lub cuab yeej.
Kev sib kis tus tshiab: hauv 400g / 800g optical modules, photoDies (xws li tus yuam sij rau kev siv ntawm kwv yees li 50 {{800 100 daim; Tsis tas li ntawd, TVs diodes yog siv los tiv thaiv cov kab ntsuas hluav taws xob siab, nrog rau kev xav tau ntawm kwv yees li 20 rau ib qho module.
Cov khoom siv cov khoom siv sib txuas lus: hauv smartphones, dongs}}}}}}}}}}}}}} device us us us us of of of of of of of of of of of of of of of of of of of of of of of of of of;; Hauv cov twj siv hluav taws xob xws li raws li cov routers, donges tau siv rau cov cim ntsuas thiab kev tiv thaiv, nrog kev siv kwv yees li 200-300 tauj ib lub cuab yeej.
2, Core Appararios ntawm diodes nyob rau hauv cov khoom siv sib txuas lus
RF teeb liab ua
RF Diode yog "lub teeb liab hloov" ntawm cov khoom sib txuas lus MHz rau Ghz) ua rau nws muaj cov yam ntxwv nrawm) ua rau nws muaj kev sib txuas lus nrawm) Piv txwv li, nyob rau hauv kav hlau txais xov mimo ntawm 5g puag ncig, schottky dodes ua tiav ultrasraft rov qab (rov qab lub sijhawm rov qab<5ns) through metal semiconductor barriers, supporting signal synthesis of 64T64R large-scale antenna arrays; In satellite communication, varactor diodes adjust the capacitance value through bias voltage to achieve low-noise signal amplification of parametric amplifiers (noise temperature<0.02dB/K), meeting the high requirements for signal-to-noise ratio in deep space communication.
Kev tswj hwm lub zog thiab ua haujlwm ua tau zoo
Lub zog module ntawm cov khoom sib txuas lus muaj cov cai nruj rau qhov poob thiab thermal stability ntawm dodes. Noj cov 5G chav nres tsheb ua piv txwv, nws cov khoom sib txuas lus 58v kev sib koom tes admoprorative tsim ntawm Gan Hemt thiab Sic Schottky Diode. Lub conduction voltage poob (vf=0.3 v) yog luv dua li ntawm 806%, thiab cov hluav taws xob rov qab los ntawm ib qho chaw nres tsheb hauv qab 100000. Nyob rau hauv lub tshuab kho qhov muag siv kho qhov muag, synchronous lub thev naus laus zis ntws ntawm cov neeg voltage thiab kev sib xyaw ua ke los ntawm kev tsim kho 400} rau 94%, txo qhov nyuaj ntawm kev tsim thermal.
Kev tiv thaiv Circuital tiv thaiv thiab kev ntseeg tau txhim kho
TVS Diode yog "Valve Valve" rau chaw nres nkoj tiv thaiv hauv cov khoom sib txuas lus. Nws cov ultra ceev teb ceev ceev (<1ps) and high clamping accuracy (± 5%) can effectively suppress electrostatic discharge (ESD) and surge voltage. For example, in data center switches, Littelfuse unidirectional TVS diodes (such as SMAJ5.0A) optimize the PN junction structure to shorten the response time to 1ps, support 30kV air discharge protection for 10/1000Base-T Ethernet ports, and meet the IEC 61000-4-5 standard; In 5G small base stations, low parasitic capacitance TVS diodes (Cj=0.5pF) control signal attenuation below 0.1dB, supporting lossless transmission of PAM4 signals.
3, thev naus laus zis thiab kev lag luam kev lag luam
Cov Khoom Siv Innovation Drives Kev Ua Tau Tshwm
Cov koob meej ntawm peb {-} tiam semiconductor cov ntaub ntawv (sic, gan) yog rov kho dua lub Diode toj roob hauv pes Diode toj roob hauv pes. Piv txwv li, Gan ntawm Pob Zeb Diamond Substrate Technology nce thermal ua kom sov mus rau 1000W / (MINW / (maple junction kub los ntawm 30 degree, thiab lub neej ntev lawm; Kev ua ke tsim ntawm Sic mosfet thiab diode ua rau lub zog hluav taws xob ntawm 5kW Base Chaw nres tsheb loj tshaj 1kW / L, ntsib qhov yuav tsum tau ua siab ntev.
Kev txawj ntse thiab kev sib xyaw ua ke tau dhau los ua cov tseem ceeb
Nyob rau yav tom ntej, ddayes yuav tsim kho ntawm kev taw qhia ntawm "ntse kev lees paub + tus kheej- kev cai". Piv txwv, sib koom ua ke ntsuas kub, thiab kev tiv thaiv tsav tsheb ntawm ib nti kom ua tiav qhov tseeb {lub sijhawm hloov kho ntawm Diroding Junction kub; Ntxiv rau, daim ntawv thov ntawm quantum tho cov nyhuv, muaj zog hloov chaw kom ncav cuag picosecond qib, muab cov kev daws teeb meem qis rau 6g kev sib txuas lus.
Hauv zej zog hloov chaw sai sai ua lag luam rov qab
Qhov loj ntawm Tuam Tshoj cov TVs DIODE kev ua lag luam yuav ncav cuag 12 txhiab xyoo hauv 2023, ib xyoos {}, nrog cov khoom sib txuas lus suav nrog rau 8.3%. Cov tuam txhab sawv cev los ntawm Suzhou Gude tau ua tiav rau lub sijhawm 70% thim rov qab los ntawm kev tshawb fawb thiab kev txhim kho sic sicdes, tawg thoob ntiaj teb monopolies; Ntawm txoj cai qib, National "TVs Diode cov phiaj xwm tseem ceeb" tau nqis peev ntawm kev ntseeg siab thiab qis} power thev naus laus zis. Nws cia siab tias los ntawm 2025, Tuam Tshoj cov TVs Diode Thoob Ntiaj Teb Kev Lag Luam yuav tshaj 40%.
