Iindaba

Aisahluli samandlawahlula isignali engenayo ibe zimbini (okanye ngaphezulu) iimpawu zemveliso. Kwimeko efanelekileyo, isahluli samandla sinokuthathwa njengelahleko-ngaphantsi, kodwa ekusebenzeni kuhlala kukho ukuchithwa kwamandla. Ngenxa yokuba inethiwekhi yokubuyiselana, umdibanisi wamandla unokuphinda asetyenziswe njengomhlanganisi wamandla, apho amazibuko amabini (okanye ngaphezulu) asetyenziselwa ukudibanisa imiqondiso yokufaka kwimveliso enye. Ngokwethiyori, ulwahluli lwamandla kunye nomdibanisi wamandla unokuba yinxalenye efanayo, kodwa ekusebenzeni kunokubakho iimfuno ezahlukeneyo zokudibanisa kunye nabahluli, njengokuphatha amandla, ukuhambelana kwesigaba, umdlalo wezibuko kunye nokuhlukaniswa.

Izahluli zamandla kunye nezihlanganisi zihlala zibizwa ngokuba ngabahluli. Ngelixa oku kuchanekile ngokobuchwephesha, iinjineli zihlala zigcina igama elithi "i-splitter" ukuze lithethe isakhiwo esingabizi kakhulu esixhathisayo esahlula amandla kwi-bandwidth ebanzi kakhulu, kodwa inelahleko enkulu kunye nokuphathwa kwamandla okuncinci.

Igama elithi "isahluli" lisetyenziswa rhoqo xa uphawu olungenayo luya kwahlulwa ngokulinganayo kuzo zonke iziphumo. Umzekelo, ukuba kukho amazibuko amabini aphumayo, ngalinye liya kufumana ngaphantsi kwesiqingatha sesiginali yegalelo, ngokufanelekileyo -3 dB xa kuthelekiswa nesiginali yegalelo. Ukuba kukho izibuko ezine eziphumayo, izibuko ngalinye liza kufumana malunga nekota enye yomqondiso, okanye -6 dB xa kuthelekiswa nomqondiso wegalelo.

Ukubekwa wedwa

Xa ukhetha ukuba loluphi uhlobo lwesahluli okanye isihlanganisi oza kusisebenzisa, kubalulekile ukuba ucinge ukuba wedwa. Ukwahlukaniswa okuphezulu kuthetha ukuba imiqondiso yesiganeko (kwisihlanganisi) ayiphazamisi enye nenye, kwaye nawaphi na amandla angathunyelwanga kwimveliso ayachithwa kunokuba athunyelwe kwizibuko eliphumayo. Iindidi ezahlukeneyo zabahluli zikuphatha oku ngeendlela ezahlukeneyo. Umzekelo, kwisahluli seWilkinson, isichasi sinexabiso le-2Z0 kwaye sibotshwe kuzo zonke iziphumo. Kwi-quadrature coupler, izibuko lesine linokupheliswa. Ukupheliswa akuchithi amandla ngaphandle kokuba kwenzeke into embi, njenge-amp enye ingasebenzi okanye i-amplifiers inezigaba ezahlukeneyo.

Iindidi zabahluli

Kukho iintlobo ezininzi kunye neentlobo ezincinci zezahluli zamandla okanye abahlanganisi. Ezimbalwa zezona ziqhelekileyo ziquka:

I-Wilkinson isahluli samandla

Isahluli se-Wilkinson sahlula isignali yegalelo ibe yimiqondiso emibini yesigaba esilinganayo, okanye idibanise iimpawu ezimbini ezilinganayo zibe enye kwicala elichaseneyo. Isahluli se-Wilkinson sithembele kwi-quarter-wave transformer ukuze sifanise izibuko elahlulahlulwe. Isichasi sibekwe kuzo zonke iziphumo, apho singenzi monakalo kumqondiso wegalelo kwiSibuko 1. Oku kuphucula kakhulu ukubekwa wedwa kwaye kuvumela onke amazibuko ukuba ahambelane ne-impedance. Olu hlobo lwesahluli luhlala lusetyenziswa kwiinkqubo zamaza kanomathotholo ezininzi kuba zinokubonelela ngenqanaba eliphezulu lokuzihlukanisa phakathi kwezibuko eziphumayo. Ngokuphosa amacandelo amaza amaninzi ekota, iWilkinson's inokuphatha ngokulula i-9:1 i-bandwidths yeenkqubo ze-electronic warfare.

Njengoko igama lisitsho, iRF/microwave isahluli samandla siya kwahlula isignali yegalelo ibe ziimpawu ezimbini ezilinganayo nezifanayo (okt kwisigaba) iimpawu. Isenokusetyenziswa njengomhlanganisi wamandla, apho izibuko eliqhelekileyo liyimveliso kunye namazibuko amabini alinganayo amandla asetyenziswa njengamagalelo. Iimpawu ezibalulekileyo xa zisetyenziswa njengesahluli samandla ziquka ilahleko yokufaka, i-amplitude kunye nebhalansi yesigaba phakathi kweengalo, kunye nokubuyisela ilahleko. Ukudibanisa amandla emiqondiso engahambelaniyo, eyona nkcazo ibaluleke kakhulu kukwahlulwa, okuyilahleko yokufaka ukusuka kwelinye izibuko lamandla elilinganayo ukuya kwelinye.

Abahluli baMandlaIimbonakalo

• Izahluli zamandla zingasetyenziswa njengezihlanganisi okanye izahluli

• I-Wilkinson kunye nezahluli zamandla zokwahlula okuPhezulu zibonelela ngokwahlulwa okuphezulu, ukuvala umqondiso wokuthetha-thethana phakathi kwamazibuko aphumayo

• Ukufakwa okuphantsi kunye nelahleko yembuyekezo

• I-Wilkinson kunye nezahluli zamandla ezichasayo zibonelela ngokugqwesileyo (<0.5dB) i-amplitude kunye (<3°) ibhalansi yesigaba

Si Chuan Keenlion Microwave ukhetho olukhulu lweendlela ezi-2 zokwahlula amandla kwi-narrowband kunye noqwalaselo lwe-broadband, egubungela amaza ukusuka kwi-DC ukuya kwi-50 GHz. Zenzelwe ukuphatha ukusuka kwi-10 ukuya kwi-30 igalelo lamandla kwi-50-ohm inkqubo yokuhambisa. Uyilo lweMicrostrip okanye lwestripline luyasetyenziswa, kwaye lulungiselelwe ukusebenza kakuhle.

Iiyunithi ziza kumgangatho kunye ne-SMA okanye i-N iziqhagamshelo zabasetyhini, okanye i-2.92mm, 2.40mm, kunye ne-1.85mm izihlanganisi zamacandelo aphezulu.

Sinokwenza ngokwezifiso isahluli samandla ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
