Yog li, rau ib lub xov tooj cua FM uas xav tau ntau dua RF lub zog thiab kev ntsuas VSWR, koj yuav xaiv lub ntsuas hluav taws xob RF zoo li cas? Muaj ob peb yam uas yuav tsum nco ntsoov thaum xaiv lub ntsuas hluav taws xob RF, uas yog hom, freq ntau, zaub, thiab cov khoom zoo. Mus nyeem ntawv ntxiv!

 

#1 Nkag siab hom

 

Yog tias koj xav yuav lub ntsuas hluav taws xob RF, ces koj yuav tsum xub nkag siab nws hom. RF fais fab ntsuas tuaj yeem muab faib ua hluav taws xob raws li RF fais fab ntsuas, diode-powered detectors, nqus RF fais fab ntsuas, thiab dhau mus. Lub ntsuas hluav taws xob raws li RF yog qhov kev xaiv zoo thaum ua cov haujlwm ntsuas kev sib xyaw ua ke, thiab lub ntsuas hluav taws xob diode yog qhov kev xaiv thaum nyeem cov theem pib lossis qhov xwm txheej yuav tsum tau ua. Tau kawg, koj kuj yuav tsum tau ua tib zoo saib seb koj lub ntsuas hluav taws xob RF puas tsim nyog rau kev sau cov cim ntsuas xws li lub zog nruab nrab, lub zog mem tes, lossis lub hnab ntawv lub zog. Thaum lub nqus RF lub zog ntsuas qhov tsim nyog rau kev tau txais cov ntaub ntawv kuaj xyuas qhov tseeb, qhov kev hla dhau ntawm RF fais fab ntsuas yog tsim nyog rau kev ua haujlwm.

 

#2 Zaus Range Matters rau qhov tseeb

 

Xaiv qhov ntau zaus yog qhov tseem ceeb. Qhov ntau zaus me me tuaj nrog qhov yuam kev ntau dua, piv txwv li, yog tias koj tab tom ua haujlwm FM transmitter nrog zaus ntawm 88 txog 108Mhz, ces 85-110Mhz RF fais fab ntsuas yog qhov koj xaiv zoo tshaj.

 

Yog tias koj feem ntau siv lub ntsuas hluav taws xob RF ntawm 1-200Mhz los ua haujlwm rau FM transmitter, ces nws qhov kev ua yuam kev yuav loj dua li lub ntsuas hluav taws xob RF nrog qhov me me. Tej zaum nws yuav ua rau muaj teeb meem xws li qhov tsis raug specs ntawm transmitter fais fab tso zis thiab kav hlau txais xov VSWR.

 

#3 Ua Commissiong yooj yim dua ntawm APP Saib Xyuas

 

Xaiv lub ntsuas hluav taws xob RF nrog APP saib xyuas tuaj yeem pab txuag koj lub sijhawm. Hom RF fais fab ntsuas no muaj cov khoom siv digital thiab cov sijhawm teev tseg. Txhawm rau tsom mus rau commissioning lub transmitter thiab kav hlau txais xov yog tag nrho sab laug ua, tsis tas yuav sau VSWR thiab xa mus rau lub zog tshwj xeeb ntawm phau ntawv ntxiv lawm! Koj paub tias qhov no txhais li cas rau koj txoj haujlwm.

 

#4 Tsis txhob tso cov khoom zoo tom qab. 

 

Lub RF fais fab ntsuas nrog qhov zoo feem ntau muaj lub neej ua haujlwm ntev - nws kuj lav koj qhov kev ua haujlwm raug. Tsis tas li ntawd, tus qauv tsim rugged muaj kev tiv thaiv ntau dua los tso cov ntsuas hluav taws xob los ntawm cov pob hauv kev thauj mus los thiab kev thauj mus los. Yog li, nco ntsoov ceev faj txog qhov zoo ua ntej muab qhov kev txiav txim rau lub ntsuas hluav taws xob RF. 

 

#5 Freq Selective lossis Freq Tsau Hom

 

Nws yog ib qho tsim nyog sau cia tias RF fais fab ntsuas ntsuas tuaj yeem yog qhov kev xaiv ntau zaus lossis zaus kho, qhov sib txawv loj tshaj ntawm ob yog qhov tseeb thiab tus nqi.

 

Piv txwv li, lub tshuab hluav taws xob RF portable los ntawm noog tuaj yeem ua tau raws li qhov kev xav tau ntawm ntau zaus sib txawv (xws li 450kHz-2.7GHz lossis 50-100MHz, thiab lwm yam) thiab lub zog hluav taws xob (xws li 100mW-10kW) los ntawm kev sib txuam fais fab. cov khoom.

 

Txawm li cas los xij, nws tus nqi tuaj yeem khiav mus rau ntau txhiab daus las. 

 

Rau feem ntau cov tshaj tawm, tus nqi muag ntau dhau, ntau zaus, thiab lub zog ntau kuj tseem tsis tsim nyog, tsis hais tias qhov kev xeem tau raug rau qhov sib txawv loj (txawm tias qhov raug lees paub yog ± 5%)

 

Piv nrog rau yav dhau los qhov dav ntau zaus thiab lub zog ntau, qhov zaus xaiv RF fais fab ntsuas muaj qhov ntsuas qhov tseeb dua thiab feem ntau pheej yig dua. 

 

Hom RF fais fab ntsuas no yog tshwj xeeb Nws yog siv los saib xyuas RF fais fab tso zis thiab VSWR tus nqi ntawm FM zaus band, uas tseem txaus los ua kom tau raws li qhov kev sib kis ntawm cov xov tooj cua FM feem ntau.
