Lub tshuab hluav taws xob microwave solid-state yog ib lub cuab yeej hluav taws xob uas siv cov khoom siv semiconductor xws li Gunn diodes, IMPATT diodes, FET transistors, HEMT transistors, thiab lwm yam los tsim cov zaus microwave electromagnetic waves (feem ntau yog xa mus rau 300MHz ~ 300GHz).

Nws txawv ntawm cov khoom siv microwave "hluav taws xob nqus tsev" ib txwm muaj xws li magnetrons, cov raj xa dej mus ncig, thiab klystrons. Cov khoom siv ib txwm muaj vam khom kev txav ntawm cov electrons dawb hauv lub tshuab nqus tsev los tsim cov microwaves, thaum cov khoom siv hluav taws xob microwave solid-state vam khom tag nrho cov yam ntxwv ntawm cov khoom siv semiconductor, tsim cov oscillations los ntawm kev txav mus los thiab kev hloov pauv zog ntawm cov electrons hauv cov qauv semiconductor lattice.

Cov yam ntxwv:

1. Qhov loj me me thiab lub teeb yuag: Lub hauv paus yog lub semiconductor chip, uas tsis xav tau cov raj nqus tsev lossis cov khoom siv hluav taws xob siab, ua rau tag nrho cov cuab yeej me me thiab yooj yim rau kev koom ua ke rau hauv cov kab ke hluav taws xob niaj hnub.
2. Qhov hluav taws xob ua haujlwm tsawg thiab muaj kev nyab xeeb siab: Feem ntau tsuas yog xav tau ob peb volts txog kaum tawm volts ntawm DC hluav taws xob qis xwb, thaum cov khoom siv hluav taws xob feem ntau xav tau ntau txhiab volts ntawm qhov hluav taws xob siab. Qhov no ua rau nws muaj kev nyab xeeb dua thiab tsim hluav taws xob yooj yim dua.
3. Lub neej ntev thiab kev ntseeg siab siab: Yog tsis muaj cov khoom siv xws li cathode filaments, lub neej theoretical ntawm cov khoom siv semiconductor ntev heev, ncav cuag kaum lossis txawm tias pua pua txhiab teev, ntau dua li cov raj microwave ib txwm muaj.
4. Kev ntshiab ntawm spectrum thiab kev ruaj khov ntawm zaus: Tshwj xeeb tshaj yog rau cov khoom siv khov kho uas siv cov thev naus laus zis theem-xauv lub voj voog (PLL), lawv tuaj yeem tsim cov teeb liab microwave ntshiab heev thiab ruaj khov heev nrog lub suab qis.
5. Kev ceev ceev thiab kev tswj hwm yooj ywm: Qhov zaus tso zis, theem, thiab qhov siab tuaj yeem hloov pauv sai thiab raug los ntawm voltage (voltage controlled oscillator VCO) lossis cov teeb liab digital, ua rau nws yooj yim los ua kom tiav cov kev hloov pauv thiab kev txawj ntse.
6. Kev tiv thaiv kev poob siab thiab kev co zoo: Nrog rau cov qauv khov kho, tsis muaj cov plhaub iav lossis cov filaments uas yooj yim tawg, ua rau nws hloov tau yooj yim rau cov chaw ua haujlwm hnyav.

Daim Ntawv Thov:

1. Lub hauv paus radar niaj hnub: Siv dav hauv tsheb millimeter nthwv dej radar, tub rog phased array radar, thiab lwm yam, kom ua tiav qhov kev tshawb pom tseeb thiab kev ntsuas ceev ceev.
2. Lub hauv paus kev sib txuas lus wireless: Nws yog ib qho tseem ceeb ntawm 5G / 6G chaw nres tsheb, kev sib txuas lus satellite, thiab cov khoom siv xa xov microwave, uas yog lub luag haujlwm rau kev tsim cov teeb liab thauj khoom siab.
3. Kev kuaj thiab ntsuas qhov tseeb: Ua lub hauv paus teeb liab, nws yog "lub plawv" ntawm cov cuab yeej siv siab xws li cov khoom siv ntsuas spectrum thiab cov khoom siv ntsuas network, kom ntseeg tau tias kev kuaj raug.
4. Cov cuab yeej siv hauv kev lag luam thiab kev tshawb fawb: Siv rau kev ua kom sov hauv kev lag luam, kev ziab, nrog rau cov khoom siv ua kom nrawm thiab cua sov plasma rau cov khoom siv sib xyaw nuclear hauv kev tshawb fawb.
5. Kev Ruaj Ntseg thiab Kev Ua Rog Hluav Taws Xob: Siv rau kev ruaj ntseg ntawm tib neeg thiab cov tshuab jamming hauv kev ua tsov rog hluav taws xob, tsim cov cim nyuaj los siv kev cuam tshuam.

Qualwavemuab lub tshuab hluav taws xob microwave solid-state nrog zaus ntawm 2.45GHz. Peb cov khoom siv dav dav hauv ntau thaj chaw.
