IZIHLUNGI ZE-CAVITY RF: ABAYENZAYO

Ngokuvamile ahlanganisa amabhlogo ensimbi amakhulu anezixhumi ze-RF ezimbalwa (2 zezihlungi nezi-3 zamaduplex ahlanganisa amasiginali we-Tx ne-Rx embotsheni eyodwa yothi).Njengoba kukhonjisiwe esithombeni esingezansi, lezi zihlungi zifaka izikulufu eziningi ohlangothini olulodwa noma ngaphezulu emizimbeni yazo.Ezinye zalezi zikulufu ziyizikulufu zokushuna, kanti ezinye zisetshenziselwa ukubophela ipuleti eliphezulu ku-chassis.

Ukuze unciphise ukulahlekelwa kwe-RF futhi uzuze ukukhetha okuphezulu kwe-Q noma isihlungi esidingekayo ukuze uthole ukulahlekelwa okuphansi kulo lonke ibhande lokudlula lesihlungi kanye nokwenqatshwa okubukhali ngaphandle kwebhande lokudlula lesihlungi, umzimba we-aluminium uhlala ucwecwe (ngesiliva, ithusi, noma igolide, kodwa kuphela ngezicelo zesikhala).

Kuwo wonke amanethiwekhi angenawaya kusukela ku-1G kuya ku-5G, kanye nasezinhlelweni zokuxhumana zomphakathi nezempi, Izihlungi ze-RF Cavity bezilokhu zisebenza futhi zisaqhubeka zisebenza embonini engenazintambo.Zinobubanzi befrikhwensi ebanzi kakhulu, esukela ku-50 MHz ukuya ngaphezulu kwama-20 GHz.Ngenxa yobude bawo obuphansi bamaza, aba mancane njengoba imvamisa ikhuphuka (ijubane lokukhanya alishintshi futhi libalwa njengomkhiqizo wefrikhwensi yesiginali ye-RF namaza ayo).

Nakuba i-passband yeningi lezinhlelo zokusebenza ezidumile iphakathi kuka-1% no-10% wefrikhwensi yokusebenza, Izihlungi ze-RF Cavity zinikeza inhlobonhlobo yezinhlelo zokusebenza ezingokoqobo njengoba ibhendi yazo yokungena ingahluka kusukela ngaphansi kuka-0.5% iye kufika ku-20% wefrikhwensi yokusebenza. .Ukuze uthole ukusebenza kahle komamukeli endaweni yangempela ye-RF, iningi, uma kungenjalo wonke, amasistimu angenawaya asebenzisa Izihlungi ze-RF Cavity phakathi kwe-Antenna neRadio (ikhawulele isignali yokufaka ye-LNA ukuze yenqabe amaza aphansi nangaphezulu ngaphandle kokusebenza kwesistimu) .

Njengoba amasiginali e-Tx enomsindo omkhulu kunanoma imaphi amasignali owamukelayo ngo-120 kuya ku-150 dB, Izihlungi ze-RF Cavity nazo zisetshenziswa kusiginali ye-Tx ukuze kuqinisekiswe ukuthi umsindo we-PA nokukhishwa kwegesi kukhawulelwe futhi azizithinti ngokwazo noma olunye uhlobo lwesistimu engenantambo.
