Izindaba

Aisihlukanisi samandlaihlukanisa isignali engenayo ibe amasignali okukhiphayo amabili (noma ngaphezulu). Esimeni esihle, isihlukanisi samandla singabhekwa njengokulahlekelwa okuncane, kodwa ekusebenzeni kuhlale kukhona ukuchithwa kwamandla. Ngenxa yokuthi iyinethiwekhi ehambisanayo, isihlanganisi samandla singasetshenziswa njengesihlanganisi samandla, lapho izimbobo ezimbili (noma ngaphezulu) zisetshenziselwa ukuhlanganisa amasignali okokufaka kube okukhiphayo okukodwa. Ngokombono, isihlukanisi samandla nesihlanganisi samandla kungaba ingxenye efanayo ncamashi, kodwa ekusebenzeni kungase kube nezidingo ezihlukene zezihlanganisi nabahlukanisi, njengokuphatha amandla, ukufaniswa kwesigaba, ukufaniswa kwembobo nokuhlukaniswa.

Izihlukanisi zamandla nezihlanganisi zivame ukubizwa ngokuthi izihlukanisi. Nakuba lokhu kuyiqiniso ngobuchwepheshe, onjiniyela ngokuvamile bayaligodla igama elithi “i-splitter” ukuze lisho isakhiwo esiphikisayo esingabizi esihlukanisa amandla phezu komkhawulokudonsa obanzi kakhulu, kodwa esinokulahlekelwa okukhulu kanye nokuphathwa kwamandla okulinganiselwe.

Igama elithi “isihlukanisi” livame ukusetshenziswa lapho isignali engenayo izohlukaniswa ngokulinganayo kukho konke okukhiphayo. Isibonelo, uma kukhona izimbobo zokuphuma ezimbili, ngayinye izothola ngaphansi kancane kwengxenye yesiginali yokufaka, kuhle -3 dB uma iqhathaniswa nesiginali yokokufaka. Uma kukhona izimbobo zokukhiphayo ezine, imbobo ngayinye izothola cishe ingxenye eyodwa yesine yesiginali, noma -6 dB uma iqhathaniswa nesiginali yokokufaka.

Ukuzihlukanisa

Uma ukhetha ukuthi yiluphi uhlobo lwesihlukanisi noma isihlanganisi ozosisebenzisa, kubalulekile ukucabangela ukuzihlukanisa. Ukuhlukaniswa okuphezulu kusho ukuthi amasiginali esigameko (esihlanganisi) awaphambanisani, futhi noma imaphi amandla angathunyelwanga kulokho okukhiphayo ayashabalala kunokuba athunyelwe embobeni yokukhiphayo. Izinhlobo ezahlukene zabahlukanisi zisingatha lokhu ngezindlela ezahlukene. Isibonelo, kusihlukanisi se-Wilkinson, isiphikisa sinevelu engu-2Z0 futhi siboshelwe kuyo yonke imiphumela. Ku-quadrature coupler, imbobo yesine inokunqanyulwa. Ukunqanyulwa akuchithi amandla ngaphandle kokuthi kwenzeke okubi, njengokuthi i-amp eyodwa ihluleka noma ama-amplifiers anezigaba ezihlukene.

Izinhlobo Zokuhlukanisa

Kunezinhlobo eziningi kanye nezinhlobo ezincane zokuhlukanisa amandla noma izihlanganisi. Okumbalwa kwezijwayeleke kakhulu kuhlanganisa:

I-Wilkinson power divider

Isihlukanisi se-Wilkinson sihlukanisa isignali yokufaka ibe amasignali okukhiphayo ezigaba ezimbili ezilinganayo, noma sihlanganise amasignali esigaba esilinganayo sibe esisodwa kwelinye elibheke ngakolunye uhlangothi. Isihlukanisi se-Wilkinson sithembele kuma-quarter-wave transformer ukufanisa imbobo ehlukanisiwe. I-resistor ibekwe kuyo yonke imiphumela, lapho ingalimazi khona isignali yokokufaka ku-Port 1. Lokhu kuthuthukisa kakhulu ukuhlukaniswa futhi kuvumela zonke izimbobo ukuthi zifaniswe ne-impedance. Lolu hlobo lwesihlukanisi luvame ukusetshenziswa ezinhlelweni zefrikhwensi yomsakazo weziteshi eziningi ngoba lunganikeza izinga eliphezulu lokuzihlukanisa phakathi kwezimbobo zokuphumayo. Ngokukhipha izingxenye zekota zamagagasi amaningi, abakwa-Wilkinson bangakwazi ukuphatha kalula ama-bandwidth angu-9:1 wezinhlelo zempi ye-elekthronikhi.

Njengoba igama lisho, isihlukanisi samandla e-RF/microwave sizohlukanisa isignali yokufaka ibe amasignali amabili alinganayo nafanayo (okungukuthi esigabeni). Ingase futhi isetshenziswe njengesihlanganisi samandla, lapho imbobo evamile iwukuphumayo nezimbobo zamandla ezimbili ezilinganayo zisetshenziswa njengokufakwayo. Ukucaciswa okubalulekile uma kusetshenziswa njengesihlukanisi samandla kufaka phakathi ukulahlekelwa kokufaka, i-amplitude nebhalansi yesigaba phakathi kwezingalo, nokulahlekelwa kokubuyisela. Ngokuhlanganiswa kwamandla amasignali angahlobene, ukucaciswa okubaluleke kakhulu ukuhlukaniswa, okuwukulahlekelwa kokufakwa kusuka kwesinye imbobo yamandla alinganayo kuya kwesinye.

Abahlukanisi AmandlaIzici

• Izihlukanisi zamandla zingasetshenziswa njengezihlanganisi noma izihlukanisi

• I-Wilkinson kanye Nezihlukanisi zamandla ezihlukanisayo Eziphezulu zinikeza ukuhlukaniswa okuphezulu, okuvimba isignali yokuxoxisana phakathi kwezimbobo zokuphumayo

• Ukufakwa okuphansi nokulahlekelwa kokubuyisela

• I-Wilkinson kanye nezihlukanisi zamandla amelana zinikeza okuhle kakhulu (<0.5dB) amplitude kanye (<3°) nebhalansi yesigaba

Si Chuan Keenlion Microwave ukukhethwa okukhulu kwezihlukanisi zamandla ezindlela ezi-2 ekucushweni kwe-narrowband ne-broadband, emboza amaza ukusuka ku-DC kuye ku-50 GHz. Zenzelwe ukuphatha amandla okufaka ama-watts asuka ku-10 kuye kwangama-30 kusistimu yokudlulisa engu-50-ohm. Imiklamo ye-Microstrip noma ye-stripline isetshenziswa, futhi yenzelwe ukusebenza kahle kakhulu.

Amayunithi eza ajwayelekile anezixhumi ze-SMA noma ze-N zesifazane, noma izixhumi ezingu-2.92mm, 2.40mm, nezingu-1.85mm zezingxenye zefrikhwensi ephezulu.

Singakwazi futhi ukwenza ngokwezifiso isihlukanisi samandla ngokwezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
