I-CAVITY RF FILTERS: INTO ABAYENZAYO

Ngokwesiqhelo ziquka iibhloko zentsimbi ezinkulu ezineziqhagamshelo ze-RF ezimbalwa (ezi-2 zezihluzi kunye nezi-3 zee-duplexer ezidibanisa imiqondiso ye-Tx ne-Rx kwizibuko le-eriyali enye).Njengoko kubonisiwe kulo mfanekiso ungezantsi, ezi zihluzi zibonisa izikrufu ezininzi kwicala elinye okanye ngaphezulu kwemizimba yazo.Ezinye zezikrufu zizikrufu zokulungisa, ngelixa ezinye zisetyenziselwa ukuqhoboshela ipleyiti ephezulu kwi-chassis.

Ukuze unciphise ilahleko yeRF kwaye ufezekise ukhetho oluphezulu lwe-Q okanye isihluzi esifunekayo ukufumana ilahleko ephantsi kulo lonke isihluzi sokugqitha kunye nokuchaswa okubukhali ngaphandle kwesihluzo sokugqitha, umzimba we-aluminium uhlala ucwecwe (ngesilivere, ubhedu, okanye igolide, kodwa kuphela. kwizicelo zendawo).

Kuzo zonke iinethiwekhi ezingenazingcingo ukusuka kwi-1G ukuya kwi-5G, kunye nakwiinkqubo zonxibelelwano lwasekuhlaleni kunye nomkhosi, iiFilters ze-RF Cavity ziye kwaye ziyaqhubeka zisebenza kushishino olungenazingcingo.Zinoluhlu olubanzi kakhulu lwamaza, ukusuka kwi-50 MHz ukuya ngaphezulu kwe-20 GHz.Ngenxa yobude bamaza asezantsi, aba mancinci njengoko amaza enyuka (isantya sokukhanya sihlala sihleli kwaye sibalwa njengemveliso yefrikhwensi yomqondiso weRF kunye nobude bayo).

Nangona i-passband kuninzi lwezicelo ezidumileyo iphakathi kwe-1% kunye ne-10% ye-frequency yokusebenza, ii-RF Cavity Filters zibonelela ngoluhlu olubanzi lwezicelo ezisebenzayo kuba i-passband yabo inokwahluka ukusuka ngaphantsi kwe-0.5% ukuya kuthi ga kwi-20% yobuninzi bokusebenza. .Ukuze ufumane eyona nkqubo ilungileyo yomamkeli kwindawo yeRF yokwenyani, uninzi, ukuba asizizo zonke, iisistim ezingenazingcingo zisebenzisa iRF Cavity Filters phakathi kweAntenna kunye neRadio (inqande umqondiso weLNA wokungenisa ukwala amaza asezantsi nangaphezulu ngaphandle kwenkqubo yokusebenza) .

Njengoko iisignali ze-Tx ziphezulu kakhulu kunayo nayiphi na imiqondiso yomamkeli nge-120 ukuya kwi-150 dB, izihluzi ze-RF Cavity nazo ziyasebenza kumqondiso we-Tx ukuqinisekisa ukuba ingxolo ye-PA kunye nezinto ezikhutshwayo zikhawulelwe kwaye azichaphazeli ngokwazo okanye naluphi na uhlobo lwenkqubo engenazingcingo.
