Dab tsi yog cov kev ua haujlwm ntawm tus pin ntawm tus pin diodes hauv 5G puag ncig?

1, Cov yam ntxwv yooj yim ntawm tus lej Pin Dodes
Pin ddays muaj los ntawm p - hom, intrinsic semiconductor (i txheej)}} hom semiconductors txheej. Nws lub hauv paus kev ua haujlwm yog raws li PN sib tshuam cov yam ntxwv ntawm cov kab ke ntawm cov cheeb tsam thiab kev tsim ntawm cov cheeb tsam depletion. Thaum xa mus rau tom ntej, qhov hauv p cheeb tsam thiab hluav taws xob hauv lub cheeb tsam kuv tau ua kom muaj huab ntawm I cheeb tsam, ua rau lub xeev tsis kam lees; Thaum thim rov qab tsis zoo, cov neeg nqa khoom tau nyiam rau thaj tsam ntawm i cheeb tsam, uas yuav luag tsis muaj nqi huab thiab muaj kev tiv thaiv lub xeev siab. Cov xeeb ceem no ua rau tus mob tus hniav muaj qhov zoo xws li poob sai sai, ua rau muaj kev haum rau qhov siab thiab nrawm} zaus thiab nrawm dua hloov chaw.
2, lub luag haujlwm ntawm PIN diode nyob rau hauv 5G chav tsev chaw nres tsheb kav hlau txais xov
(1) cov kev sib txuam sib xyaw
Nyob rau hauv 5G luj pib noj, cov zis phim network ntawm RF lub zog hluav taws xob yuav tsum tau hloov kho kom zoo thiab txhim kho cov hluav taws xob ua tau zoo thiab ruaj khov. Tus yam ntxwv tsis sib haum xeeb ntawm tus lej tooj ntawm tus pin diodes ua rau lawv xaiv zoo tshaj plaws rau kev ua tiav txoj haujlwm no. Piv txwv li, hauv qhov l {{3} Zoo nkauj sib piv network, tus lej PIN dongs tau txuas nrog hauv salterors thiab capacitors. Los ntawm kev hloov nws txoj kev tsis ncaj ncees tam sim no, tus nqi impedance tuaj yeem hloov kho tsis tu ncua, yog li hloov cov yam ntxwv ntawm cov khoom sib piv ntawm lub network sib piv. Hauv 100mHz RF Circuit Cours, thaum tus PIN diode kev hloov pauv hloov, lub impedance hloov tau los ntawm kaum tawm ntawm kev hloov pauv kev sib txuam ntawm cov kev sib txuam nrog cov imporing network impedance.
(2) Kev yoog kev sib xyaw ua ke
5G lub chaw nres tsheb yuav tsum txhawb kev sib txuas lus thoob plaws ntau zaus los ua kom tiav cov ntaub ntawv dav dav thiab siab} cov ntaub ntawv ceev kis.
