Izindaba

Aisihlukanisi samandlaihlukanisa isignali engenayo ibe yizimpawu ezimbili (noma ngaphezulu) zokukhipha. Esimweni esifanele, isihlukanisi samandla singabhekwa njengesingenakulahlekelwa, kodwa empeleni kuhlale kukhona ukuhlakazeka kwamandla. Ngenxa yokuthi iyinethiwekhi ephindaphindayo, isihlanganisi samandla singasetshenziswa futhi njengesihlanganisi samandla, lapho kusetshenziswa khona amachweba amabili (noma ngaphezulu) ukuhlanganisa izimpawu zokufaka zibe umphumela owodwa. Ngokwethiyori, isihlukanisi samandla kanye nesihlanganisi samandla kungaba yingxenye efanayo, kodwa empeleni kungaba nezidingo ezahlukene zabahlanganisi kanye nabahlukanisi, njengokuphathwa kwamandla, ukufaniswa kwesigaba, ukufaniswa kwephothi kanye nokuhlukaniswa.

Abahlukanisi bamandla kanye nabahlanganisi bavame ukubizwa ngokuthi abahlukanisi. Nakuba lokhu kuyiqiniso ngokobuchwepheshe, onjiniyela bavame ukugcina igama elithi “umhlukanisi” lisho isakhiwo esingabizi kakhulu esihlukanisa amandla phezu komkhawulokudonsa obanzi kakhulu, kodwa sinokulahlekelwa okukhulu kanye nokuphathwa kwamandla okulinganiselwe.

Igama elithi “umhlukanisi” livame ukusetshenziswa kakhulu lapho isignali engenayo izohlukaniswa ngokulinganayo kuzo zonke iziphumayo. Isibonelo, uma kunezimbobo ezimbili zokukhipha, ngayinye izothola ngaphansi kancane kwengxenye yesignali yokufaka, okungcono kakhulu -3 dB uma kuqhathaniswa nesignali yokufaka. Uma kunezimbobo ezine zokukhipha, imbobo ngayinye izothola cishe ingxenye eyodwa kwezine yesignali, noma -6 dB uma kuqhathaniswa nesignali yokufaka.

Ukuzihlukanisa

Uma ukhetha ukuthi yiluphi uhlobo lwesihlukanisi noma isihlanganisi ozosisebenzisa, kubalulekile ukucabangela ukuhlukaniswa. Ukuhlukaniswa okuphezulu kusho ukuthi izimpawu zesigameko (ku-combiner) aziphazamisi, futhi noma yimaphi amandla angathunyelwanga kumphumela ayahlakazeka kunokuba athunyelwe echwebeni lokuphuma. Izinhlobo ezahlukene zezihlukanisi zisingatha lokhu ngezindlela ezahlukene. Isibonelo, ku-Wilkinson divider, i-resistor inenani elingu-2Z0 futhi iboshwe kuzo zonke iziphumayo. Ku-quadrature coupler, ichweba lesine linokuphela. Ukuqedwa akuqedi amandla ngaphandle kokuthi kwenzeke into embi, njengokuthi i-amp eyodwa iyahluleka noma ama-amplifier anezigaba ezahlukene.

Izinhlobo Zabahlukanisi

Kunezinhlobo eziningi kanye nezinhlobo ezincane zezihlukanisi zamandla noma izihlanganisi. Ezimbalwa kwezivame kakhulu zifaka:

Isihlukanisi samandla saseWilkinson

Isihlukanisi seWilkinson sihlukanisa isignali yokufaka ibe yizibonakaliso ezimbili zokukhipha ezilinganayo, noma sihlanganise izimpawu ezimbili zesigaba esilinganayo zibe yinye ohlangothini oluphambene. Isihlukanisi seWilkinson sithembele kuma-transformer e-quarter-wave ukuze sifane ne-split port. I-resistor ibekwa ngaphesheya kwe-outputs, lapho ingalimazi khona isignali yokufaka ePort 1. Lokhu kuthuthukisa kakhulu ukuhlukaniswa futhi kuvumela wonke ama-port ukuthi ahambisane ne-impedance. Lolu hlobo lwesihlukanisi luvame ukusetshenziswa ezinhlelweni ze-frequency radio frequency eziningi ngoba lunganikeza izinga eliphezulu lokuhlukaniswa phakathi kwama-output ports. Ngokuhlanganisa izingxenye ezengeziwe zama-quarter wave, iWilkinson's ingaphatha kalula ama-bandwidth angu-9:1 wezinhlelo zempi ze-elekthronikhi.

Njengoba igama lisho, isihlukanisi samandla se-RF/microwave sizohlukanisa isignali yokufaka ibe yizibonakaliso ezimbili ezifanayo nezilinganayo (okungukuthi esigabeni). Singasetshenziswa futhi njengesihlanganisi samandla, lapho imbobo evamile ingumphumela kanti amambobo amabili alinganayo amandla asetshenziswa njengokufakwayo. Imininingwane ebalulekile uma isetshenziswa njengesihlukanisi samandla ifaka phakathi ukulahlekelwa kokufakwa, ibhalansi ye-amplitude kanye nesigaba phakathi kwezingalo, kanye nokulahlekelwa kokubuya. Ngokuhlanganisa amandla kwezibonakaliso ezingahlobene, incazelo ebaluleke kakhulu ukuhlukaniswa, okuwukulahlekelwa kokufakwa kusuka kwelinye imbobo yamandla elinganayo kuya kwelinye.

Abahlukanisi BamandlaIzici

• Izihlukanisi zamandla zingasetshenziswa njengezihlanganisi noma izihlukanisi

• Izihlukanisi zamandla ze-Wilkinson kanye ne-High solitation zinikeza ukuhlukaniswa okuphezulu, ukuvimba izingxoxo phakathi kwama-port okukhiphayo

• Ukufakwa okuphansi kanye nokulahlekelwa kokubuya

• I-Wilkinson kanye nezihlukanisi zamandla okumelana zinikeza i-amplitude enhle kakhulu (<0.5dB) kanye ne-phase balance (<3°)

I-Si Chuan Keenlion Microwave iyinhlobo enkulu yezihlukanisi zamandla ezinezindlela ezimbili ekucushweni kwe-narrowband kanye ne-broadband, ezimboza amaza kusukela ku-DC kuya ku-50 GHz. Zenzelwe ukuphatha amandla okufaka angama-watts ayi-10 kuya kwangu-30 ohlelweni lokudlulisa olungama-ohm angu-50. Kusetshenziswa imiklamo ye-Microstrip noma ye-stripline, futhi ilungiselelwe ukusebenza kahle kakhulu.

Amayunithi eza nezixhumi ezijwayelekile ze-SMA noma ze-N zesifazane, noma izixhumi ezingu-2.92mm, 2.40mm, kanye ne-1.85mm zezingxenye zemvamisa ephezulu.

Singakwazi futhi ukwenza ngokwezifiso isihlukanisi samandla ngokwezidingo zakho. Ungangena ekhasini lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
