Xov Xwm Kev Lag Luam

Lub tshuab tiv thaiv drone ntawm Mars RF siv tus qauv tsim modular, sib xyaw ua ke tag nrho kev nrhiav, kev txheeb xyuas, kev taug qab, thiab kev tiv thaiv xov tooj cua zaus kom muab kev tiv thaiv sai thiab zoo rau cov hom phiaj tseem ceeb. Lub tshuab muaj peev xwm ua haujlwm txhua lub caij, teb sai heev, thiab tiv taus kev tawm tsam ntau yam, zoo tiv thaiv ntau yam kev hem thawj ntawm drone, suav nrog ib lub drone thiab cov swarms.

Cov raj xa hluav taws xob mus ncig (TWTs), ua tus sawv cev ntawm cov thev naus laus zis hluav taws xob nqus tsev, ib zaug tau tswj hwm cov zaus tshwj xeeb thiab cov qib fais fab. Txawm li cas los xij, cov khoom siv hluav taws xob khov kho (SSPAs), nrog rau kev tshawb pom tshiab hauv cov ntaub ntawv semiconductor, tshwj xeeb tshaj yog kev loj hlob ntawm gallium nitride (GaN) thev naus laus zis, tab tom hloov kho qhov kev lag luam.

Cov solid state power amplifiers yog lub hauv paus ntawm cov wireless systems niaj hnub no, tab sis lawv lub peev xwm nthuav dav tshaj qhov 'signal amplification' xwb. Ua ib lub tuam txhab tsim khoom tshwj xeeb uas muaj ob xyoo caum ntawm kev txawj ntse hauv RF domain, Mars RF piv cov solid state power amplifiers (SSPA) rau 'powerhouse' ntawm tag nrho RF system. Los ntawm tsib lub luag haujlwm tseem ceeb, nws txhaj cov zog tseem ceeb rau hauv radar, kev sib txuas lus, thiab cov electronic countermeasure systems.

Cov Amplifiers Narrowband yog "cov neeg ua haujlwm tshaj lij" uas nrhiav kev ua tau zoo ntawm ib qho zaus tshwj xeeb. Cov amplifiers fais fab dav dav, ntawm qhov tod tes, yog cov "txhua yam" uas hloov tau yooj yim dua. Qhov sib txawv tseem ceeb ntawm ob hom amplifiers fais fab yog los ntawm lawv lub hom phiaj tsim qauv sib txawv, uas ua rau lawv txoj kev siv tshuab sib txawv thiab cov yam ntxwv ua tau zoo sib txawv. Hais yooj yim, cov amplifier narrowband nrhiav "kev ua tau zoo ib qho," thaum cov amplifiers fais fab dav dav ua tiav "kev sib raug zoo dav dav."

Kev ua kom lub teeb liab pulse amplifier nrov dua li kev ua kom lub teeb liab pulse amplifier nrov dua. Qhov teeb meem tseem ceeb yog lub amplifier muaj peev xwm hloov ntawm "off" mus rau "full power on" thiab rov qab mus rau "off" hauv nanoseconds lossis picoseconds, tswj tau qhov tseeb ntawm lub pulse shape thoob plaws hauv cov txheej txheem no. Txhua qhov kev cuam tshuam me me, xws li kev tig sab saud, overshoot, lossis ringing, yuav txhais ncaj qha mus rau qhov tsis meej ntawm lub hom phiaj, txo qhov kev daws teeb meem, lossis qhov yuam kev me ntsis hauv kev sib txuas lus hauv lub radar system. Mars RF, siv nws txoj kev paub tob hauv daim teb no, piav qhia txog yuav ua li cas kom ua tiav qhov kev cuam tshuam tsis muaj kev cuam tshuam thiab qhia txog cov kev daws teeb meem tshiab.

Hauv cov tshuab hluav taws xob niaj hnub (RF) xws li kev sib txuas lus wireless, kev tshawb nrhiav radar, thiab kev tiv thaiv hluav taws xob, cov amplifiers, tshwj xeeb tshaj yog lub zog amplifiers (PAs), ua lub luag haujlwm tseem ceeb thiab tseem ceeb. Zoo li "lub plawv" ntawm lub kaw lus, lawv muab lub zog tseem ceeb rau tag nrho cov teeb liab, txiav txim siab ncaj qha rau qhov ntau thiab tsawg ntawm kev sib txuas lus, qhov tseeb ntawm kev tshawb nrhiav, thiab kev ntseeg siab ntawm lub kaw lus.

Nyob rau hauv lub hnub nyoog digital uas sib txuas thoob ntiaj teb niaj hnub no, kev sib txuas lus satellite ua lub luag haujlwm tseem ceeb hauv kev hla dhau cov ciam teb ntawm thaj chaw. Hauv plawv ntawm qhov kev sib txuas lus hauv av no, High Power Amplifiers (HPA) ua lub luag haujlwm tseem ceeb thiab tsis tuaj yeem hloov pauv tau - ua haujlwm zoo li "cov suab nrov muaj zog" ntawm tag nrho lub kaw lus sib txuas lus satellite, kom ntseeg tau tias cov teeb liab hauv av tuaj yeem ncav cuag satellites kaum txhiab mais deb kom meej thiab ruaj khov.

Hauv kev siv lub zog fais fab ntawm xov tooj cua, kev xaiv cov khoom siv thev naus laus zis cuam tshuam ncaj qha rau qhov kev ua tau zoo ntawm lub kaw lus. Tam sim no, GaAs (Gallium Arsenide) thiab GaN (Gallium Nitride), ua ob lub thev naus laus zis semiconductor tseem ceeb, ua lub luag haujlwm tseem ceeb hauv cov kab ke wireless niaj hnub no vim lawv cov txiaj ntsig zoo tshwj xeeb.

Nyob rau hauv cov teb niaj hnub no uas kev sib txuas lus wireless, aerospace, thiab kev tiv thaiv thev naus laus zis tab tom loj hlob sai, kev hloov pauv thev naus laus zis uas coj los ntawm kev tshawb fawb txog cov ntaub ntawv tau pib ua ntsiag to. Gallium nitride (GaN) amplifiers, ua cov neeg tsim kho tshiab hauv kev siv hluav taws xob hauv xov tooj cua (RF), tab tom txhais cov qauv kev siv hluav taws xob ntawm cov amplifiers nrog lawv cov kev ua tau zoo tshaj plaws.

Hauv cov thev naus laus zis tshiab xws li 5G kev sib txuas lus, radar nrhiav, thiab kev ua tsov rog hluav taws xob, RF lub zog amplifiers ua lub luag haujlwm tseem ceeb. Raws li "lub plawv muaj zog" ntawm lub kaw lus wireless, lawv cov hauv paus ntsiab lus ua haujlwm cuam tshuam ncaj qha rau qhov kev ua tau zoo ntawm tag nrho lub kaw lus. Niaj hnub no, peb yuav nkag mus rau hauv cov ntsiab cai tseem ceeb ntawm RF lub zog amplifiers, qhia txog lawv hloov cov teeb liab tsis muaj zog mus rau hauv lub zog RF muaj zog li cas.
