Txoj kab li cas ntawm tus mob tus mob tus kabmob cuam tshuam rau kev sib txuas lus zoo?

Kev tsom xam ntawm cov yam ntxwv ntawm PIN diode
1. Kev txhais thiab sim cov qauv ntawm kab
Cov kab ntawv sab nrauv ntawm txoj kev sib raug zoo ntawm cov paib tawm ntawm lub cuab yeej xws li 1DB compression taw tes (P1DB compression) thiab thib peb} Kev txiav txim siab intermodulation txiav (iP3). Cov hau kev ntsuas ntsuas suav nrog dua ob lub suab sib npaug (thov ob lub zog sib npaug Noj cov Avago HSMP-381X Series Ua ib qho piv txwv, nws cov qauv siv I6 9}} dbm, uas yog 15db siab dua li schottky donottky donges.
2. Tsis Muaj Zog Txheej Txheem
Tus tsis yog tus lej ntawm tus lej ntawm tus lej ntawm tus lej ntawm:
Intrinsic txheej Carrier Kev Txhim Kho: Cov neeg tua hluav taws xob lub neej ntawm kuv txheej, thiab cov cim tsis tiav hauv qab high- zaus kos npe ua rau tsis muaj kev pab cuam.
Junction Captance Hloov: Thaum thim kev sib tw, lub tshav dav hlau muaj peev xwm hloov pauv nrog voltage, ua rau muaj kev hloov pauv hauv qhov kev txiav txim ntawm RF cim.
Thermal Effect: Cov phiajcim hluav taws xob siab ua rau muaj kev sib tshuam kub, nrog rau cov hluav taws xob nce toj ntawm -2MV / degree.
3. Txom Nyem Cov Lus Qhia
Kuv - txheej tuab: cov tuab tuab: cov tuab tuab heev} {luas las, lub ntev cov cab kuj dua lub sijhawm thiab qis dua qhov nonlinearity. Kuv - txheej thickness ntawm hsmp {}} 3816 mus txog ntawm cov khoom siv nrog I-txheej tuab ntawm 3 μ m.
Bias tam sim no: Thaum mus rau tom ntej kev nce qib tam sim no nce los ntawm 1ma mus rau 10MA, IPP nce los ntawm 6DB.
Qhov kub thiab txias: hauv qhov kub thiab txias ntawm -40℃rau +85 degree, lub cuab yeej ntawm lub cuab yeej tuaj yeem ncav cuag ± 3dB.
Qhov cuam tshuam ntawm kab ntawm kab ntawm kev sib txuas lus zoo
1. Cov teeb liab distortion
Krodiste distortion: Nonlinar Ua rau cov paib lub hnab ntawv dedortion thiab deterbation ntawm ntsis yuam kev (ber). Raws li 16qam kev hloov kho, rau txhua 10dB txo qis hauv IP3, tus ber nce los ntawm ib qho kev txiav txim ntawm qhov ntau.
Theem Distortion: AM {{{{{{{{} pm hloov pauv ua rau muaj kev sib hloov constellation sib hloov, cuam tshuam rau kev ua kom zoo ua tau. Hauv ib qho 64qam system, rau txhua 1℃nce nyob rau hauv theem suab, EVM tsis zoo los ntawm 0.5%.
2. Kev cuam tshuam cuam tshuam kev cuam tshuam
Thib peb xaj intermodulation (IM3): Hauv lub xov tooj dual kev sim, IM3 cov khoom yuav poob rau hauv kev tau txais zaus zaus. Hauv FDD cov chaw nres tsheb hauv FDD, qhov sib txawv zaus ntawm IM3 cov khoom lag luam thiab cov cim oscillator hauv zos yuav cuam tshuam nrog Uplink.
Hla kev tawm tsam (XM): Cov cim kev cuam tshuam daws teeb meem yog hloov kho mus rau cov cim qhia tau los ntawm cov khoom siv tsis tau siv. Hauv Wi Fi 6E cov kab ke, XM cov khoom lag luam yuav ua rau 20db txo qis nyob rau hauv ib sab ntiag tug channel cuam tshuam piv tiag (Acir).
3. Lub zog hloov pauv
1dB compression taw tes taw: thaum lub hwj chim tawm tshaj P1DB, tso zis lub zog kev loj hlob qeeb qeeb. Nyob rau hauv radar tau, rau txhua 1dB txo hauv P1DB, qhov kawg yog qhov kev ncua deb ntawm 6%.
Thaiv cov nyhuv: kev cuam tshuam cuam tshuam cov ntsiab lus sentrate sab xub ntiag ntawm tus txais, ua rau ib qho txo ​​qis hauv rhiab. Nyob rau hauv 5G nyine, thaiv cov cim yuav ua rau pom kev rhiab los ntawm 30dB.
Kev Lag Luam Thov Kev Ntsuam Xyuas
{{0 {}} g puag ncig chaw nres tsheb rf hloov
Ib qho chaw tsim khoom siv siv HSMP-3816 Series PIN Diode rau tsim RF hloov, ua tiav:
Kev nkag mus: 0.3dB (cov nqi raug)
Qib Rho Tawm: 45DB
Ip3: +52 dbm
Piv rau cov tsoos Gaas Mesfet cov khoom lag luam yog txo los ntawm 15DB, ua rau muaj kev nce qib 8% nce ntxiv hauv qhov chaw nres tsheb hauv paus.
2. Satenite Kev Txuas Lus Hwjtim
Ib qho chaw so payload siv lub PIN diode variabtor kom ua tiav:
Locenuation Nights: 0-30DB
Attenuation tiaj: ± 0.5db
Ip3: +48 dbm
Hauv tej Carrier ua haujlwm hom, EVM tau ua kom zoo los ntawm 3.5% rau 1.2%, ntsib txoj cai ntawm DVB- S2X Txuj Ci.
3. Radar System Limag
Ib phased array radar siv tus lej PIN diode unlimiter kom ua tiav:
Limited Flinehol: +20 dbm
Kev nkag mus poob: 0.8DB
Rov qab lub sijhawm: 10ns
Nyob rau hauv ib puag ncig muaj zog, sab pem hauv ntej-}}}}}} end end end protection eff effeasedeased of eff eff eff eff eff of eff eff eff eff eff eff eff eff eff eff eff eff end}, end},, thiab lub hom phiaj kuaj tau qhov kev tshwm sim tau nce los ntawm 15%.
Txhim kho cov tswv yim zoo thiab thev naus laus zis
1. Ntaus qib qib kev txhim kho
Cov Khoom Siv Innovation: Siv Silicon Carbide (Sic) Raws Voltage yog nce rau 1200V, thiab UPPTION {{2} dbm.
Txheej Txheem Tsim Qauv: Tsim ib peb {- dideional sib xyaw nrog 0.2pf thiab} pm conversion coefficient ntawm tsawg dua 0.5℃/ db.
2. Circuit Court theem kev ua kom zoo
Kev siv mis nyuj: ntsuas kub them kev lag luam yog siv los xyuas kom meej tias qhov ntsuas kub ntawm -40℃rau {2} ±℃tsawg dua ± 1dB.
Kev Siv Txoj Kev Zoo Li Cas: Qhia tawm cov kab ke tsis zoo nyob hauv tus deluatator nyob rau hauv lub delenuator los ua kom lub delenuation tiaj tus mus rau ± 0.2db.
3. Cov txheej txheem qib kev txhim kho qib
Digital Pre distortion (DPD): ua ke nrog tus lej PIN nonlinear, ACLR ntawm cov khoom xa tawm tau nce los ntawm 25DB.
Kev Tsaws Kev Tiv Thaiv: Dynamically Kho qhov kev tsis ncaj ncees tam sim no raws li cov teeb liab fais fab kom nce P1DB los ntawm 3DB.
