Iindaba

Aisahluli samandlayahlula isignali engenayo ibe ziimpawu ezimbini (okanye ezingaphezulu) zokukhupha. Kwimeko efanelekileyo, isahluli samandla sinokuthathwa njengesingenalahleko, kodwa ekusebenzeni kusoloko kukho ukuchithwa kwamandla. Ngenxa yokuba yinethiwekhi ejikelezayo, isahluli samandla singasetyenziswa njengesihlanganisi samandla, apho kusetyenziselwa khona amazibuko amabini (okanye ngaphezulu) ukudibanisa iimpawu zokufaka kwisiphumo esinye. Ngokwethiyori, isahluli samandla kunye nesihlanganisi samandla zinokuba yinxalenye efanayo, kodwa ekusebenzeni kunokubakho iimfuno ezahlukeneyo zabahlanganisi kunye nabahluli, njengokuphathwa kwamandla, ukufanisa isigaba, ukufanisa izibuko kunye nokuhlukaniswa.

Abahluli bamandla kunye nabahlanganisi badla ngokubizwa ngokuba ngabahluli. Nangona oku kuchanekile ngokwetekhnoloji, iinjineli zihlala zigcina igama elithi "i-splitter" njengelithetha isakhiwo esingabizi kakhulu esihlukanisa amandla kwi-bandwidth ebanzi kakhulu, kodwa sinelahleko enkulu kunye nokuphathwa kwamandla okulinganiselweyo.

Igama elithi “divider” lisetyenziswa rhoqo xa isignali engenayo iza kwahlulwa ngokulinganayo kuzo zonke iziphumo. Umzekelo, ukuba kukho iiport ezimbini zokukhupha, nganye iya kufumana ngaphantsi kancinci kwesiqingatha sesignali yokungenisa, kungcono ukuba ibe yi--3 dB xa ithelekiswa nesignali yokungenisa. Ukuba kukho iiport ezine zokukhupha, iport nganye iya kufumana malunga nekota yesignali, okanye i--6 dB xa ithelekiswa nesignali yokungenisa.

Ukubekwa wedwa

Xa ukhetha uhlobo lokwahlulahlula okanye lokudibanisa oluza kusetyenziswa, kubalulekile ukuqwalasela ukwahlukanisa. Ukwahlukanisa okuphezulu kuthetha ukuba imiqondiso yesiganeko (kwi-combiner) ayiphazamisani, kwaye naliphi na amandla angathunyelwanga kwisiphumo ayachitheka endaweni yokuthunyelwa kwi-output port. Iindidi ezahlukeneyo zabahlukanisi zisingatha oku ngeendlela ezahlukeneyo. Umzekelo, kwi-Wilkinson divider, i-resistor inexabiso le-2Z0 kwaye ibotshelelwe kuzo zonke iziphumo. Kwi-quadrature coupler, i-fourth port ine-termination. Ukuphela kwamandla akuchitheki ngaphandle kokuba kwenzeke into embi, njenge-amp enye engasebenziyo okanye ii-amplifier zinezigaba ezahlukeneyo.

Iintlobo zabahluli

Kukho iintlobo ezininzi kunye neentlobo ezahlukeneyo zezahluli zamandla okanye ezidibanisa amandla. Ezinye zezona zixhaphakileyo ziquka:

Isihluzi samandla saseWilkinson

Isihluli seWilkinson sahlula isignali yokufaka ibe ziimpawu ezimbini ezilinganayo zephase output, okanye sidibanise imiqondiso emibini elinganayo yephase ibe yinye kwicala elichaseneyo. Isihluli seWilkinson sixhomekeke kwiitransformer zekota-wave ukuze zihambelane ne-split port. I-resistor ibekwa ngaphaya kwee-output, apho ingenzakalisi isignali yokufaka kwiPort 1. Oku kuphucula kakhulu ukuhluthwa kwaye kuvumela zonke ii-ports ukuba zihambelane ne-impedance. Olu hlobo lwesihluli luhlala lusetyenziswa kwiinkqubo zerediyo ezininzi kuba lunokubonelela ngomlinganiselo ophezulu wokuhluthwa phakathi kwee-output ports. Ngokususa amacandelo amaninzi ekota-wave, iiWilkinson zinokusingatha ngokulula ii-bandwidths ze-9:1 zeenkqubo zemfazwe ze-elektroniki.

Njengoko igama lisitsho, isahluli samandla se-RF/microwave siya kwahlula isignali yokufaka ibe ziimpawu ezimbini ezifanayo nezilinganayo (oko kukuthi, kwisigaba). Ingasetyenziswa njengesixhobo sokudibanisa amandla, apho izibuko eliqhelekileyo liyimveliso kwaye iizibuko zamandla ezimbini ezilinganayo zisetyenziswa njengezixhobo zokungenisa. Iinkcukacha ezibalulekileyo xa zisetyenziswa njengesixhobo sokwahlula amandla ziquka ukulahleka kokufakwa, i-amplitude kunye ne-phase balance phakathi kweengalo, kunye nokulahleka kokubuya. Kwizixhobo zokudibanisa amandla zezibonakaliso ezingadibaniyo, eyona nkcazelo ibalulekileyo kukwahlulwa, okukukulahleka kokufakwa ukusuka kwelinye izibuko lamandla elilinganayo ukuya kwelinye.

Abahluli bamandlaIimbonakalo

• Izihluzi zamandla zingasetyenziswa njengezihlanganisi okanye izihluzi

• Izihluli zamandla zeWilkinson kunye neHigh solidation zibonelela nge-isolidation ephezulu, zivimba i-cross talk phakathi kwee-output ports

• Ukufakwa okuphantsi kunye nokulahleka kokubuya

• I-Wilkinson kunye nezahluli zamandla ezikhuselayo zibonelela nge-amplitude egqwesileyo (<0.5dB) kunye ne-phase balance (<3°)

I-Si Chuan Keenlion Microwave lukhetho olukhulu lwezahluli zamandla eendlela ezimbini kwiindlela ezinqamlezileyo kunye ne-broadband, ezigubungela amaza ukusuka kwi-DC ukuya kwi-50 GHz. Zenzelwe ukuphatha amandla okufaka ukusuka kwi-10 ukuya kwi-30 watts kwinkqubo yokudlulisela ye-50-ohm. Uyilo lwe-Microstrip okanye lwe-stripline luyasetyenziswa, kwaye lulungiselelwe ukusebenza kakuhle.
