Vim li cas tus pin diodes dav siv nyob rau hauv kev sib txuas lus kev lag luam?

1, cov yam ntxwv zoo: Lub cev zoo ntawm tus lej PIN diodes
Qhov tseem ceeb ntawm tus lej PIN ntawm cov lus dag nyob hauv nws cov cim p} Kuv}}}}}} hom semiconductor thiab} hom semiconductor. Tus qauv no muab nws qhov txiaj ntsig tseem ceeb:
Siab rov qab cuam tshuam voltage: muaj ntawm kuv txheej ua kom tus lej Pin Piv txwv li, qhov ncauj lus rov qab tawg ntawm qee hom PIN ntawm PIN
Tsis muaj kev thim rov qab tam sim no: lub siab tiv taus cov yam ntxwv ntawm kuv txheej tseem ceeb txo qhov thim rov qab tam sim no. Kev sim cov ntaub ntawv qhia tau tias kev thim rov qab ntawm tus lej Pin tam sim no ntawm kev txiav txim siab yog peb qhov kev txiav txim ntawm qis dua li ntawm downes downes.
Txoj kev sib raug zoo heev: Cov txheej txheem depletion dav ntawm kuv txheej muab kev sib raug zoo ntawm cov kab thiab hluav taws xob thaum tom ntej tsis muaj cai tsawg dua 0.5%.
Cov Cuam Tshuam Cov Ntsiab Lus ceev: Txawm tias muaj kev rov qab sai sai, qhov kev caij tsheb rov qab ua rau lawv ua tau zoo hauv kev siv siab. Ib hom phiaj ntawm tus lej PIN muaj ib qho hloov nrawm ntawm kaum ntawm vib nas this ntawm ib zaus ntawm 1GHz.
Cov yam ntxwv tsis tshua muaj suab nrov: cov cab kuj siab thiab tiam yog tsawg, ua rau muaj suab nrov hauv teeb liab ntawm kev ua cov cim tooj ntawm tus lej tooj.
2, Daim ntawv thov kom zoo dua: ntau cov kev pab cuam tshuam hauv kev sib txuas lus kev lag luam
Qhov kev thov cuam tshuam ntawm tus pin down
RF Hloov:
Muaj nuj nqi: Tswj teeb liab rau / tawm los ntawm Bias voltage kom ua tiav siab - zaus teeb liab txoj kev hloov.
Cov ntaub ntawv: Ib yam 5G Chaw Chaw Nres Tsheb USES khawm nrog hloov ceev ntawm Dana vib nas this, qhov kev sib tw poob ntawm 0.2db, thiab txhawb nqa cov kab cim hluav taws xob ntau.
Hostenator:
Muaj nuj nqi: series lossis sib yuav pin dodes tau siv los tswj lub teeb liab thiab tiv thaiv cov khoom siv tau txais.
Cov tsis muaj: ib hom cim tus pin ntawm delenuator muaj ntau yam ntawm 60db thiab kev hloov kho qhov tseeb ntawm 0.5db, siv rau kev hloov kho lub suab sib txuas lus lub zog.
Modulator:
Muaj nuj nqi: kev daws qhov qes - zaus taw qhia kom high- zaus nqa khoom siv rau kev sib kis rau kev kis rau kev nkag mus rau kev nkag mus rau cov paib.
Cov txiaj ntsig zoo: Cov khoom siv hluav taws xob muaj qee tus PIN diode modulator, nrog kev hloov kho lub nrawm nrawm dua 40dbm.
Photodetector:
Muaj nuj nqi: Hloov cov cim kho qhov muag rau hauv cov cim hluav taws xob rau siv hauv kev sib txuas lus kho tshuab.
Kev Ua Tau Zoo: Qhov tseeb fiber ntau cov fiber ntau kev sib txuas lus siv tus lej Psodiodes nrog cov lus teb ntawm 10GHz, thiab qhov rhiab ntawm -20DBM.
Limiter thiab Kev Tiv Thaiv Circuit:
Kev Ua Haujlwm: Kev Txwv Kev Txwv Kev Ua Yeeb Yam thiab Tiv Thaiv Cov Kev Tiv Thaiv Kev Mob.
Daim Ntawv Thov: Ib yam khoom sib txuas lus ua tub rog tau txais yuav tus Pin Diode unlimiter, uas muaj peev xwm los txhawb kev cuam tshuam ntawm kev cuam tshuam txog 30dB thiab cov lus teb ceev ntawm nanoseconds.
3, kev nce qib hauv cov ntaub ntawv tshawb fawb: catalysts nrog kev ua tau zoo
Kev tawg hauv cov ntaub ntawv kev tshawb fawb yog rov kho cov ciaj ntawm kev ua tau zoo ntawm tus lej PIN DIODES:
Cov ntaub ntawv tshiab semiconductor:
Gallium Nitride (Gan): Txhim kho cov hluav taws xob ceev thiab kub ua kom zoo, haum rau 5g millimeter txaus kev sib txuas lus.
Gallium arsenide (gaas): nce ntau zaus teb rau 60gz thiab txhawb multi {{hom thiab ntau zaus sib txuas lus.
Txhim kho cov txheej txheem npaj:
Ion Tsis txhob siv technology: Kev tswj hwm ntawm doping concentration rau txhim kho cov cuab yeej ruaj khov.
Ib Leeg Crystal kev loj hlob thev naus laus zis: Txhim kho cov khoom siv purity thiab txo kev puas tsuaj.
Tsim qauv txheej txheem tshiab:
Cov qauv qauv: txo cov ntug capacitance thiab nce kev ua haujlwm nce.
Ntsug qauv: Txhim kho txoj kev tam sim no thiab nce lub zog muaj peev xwm.
