Nyob rau hauv niaj hnub wireless kev sib txuas lus systems, duplexers, triplexers thiab quadplexers yog ib qho tseem ceeb passive Cheebtsam rau ua kom tiav multi-band teeb liab kis tau tus mob. Lawv sib txuas lossis cais cov cim qhia los ntawm ntau lub suab paj nruag, tso cai rau cov khoom siv xa mus thiab tau txais ntau lub suab paj nruag ib txhij thaum sib qhia cov kav hlau txais xov. Txawm hais tias muaj qhov sib txawv ntawm cov npe thiab cov qauv, lawv cov hauv paus ntsiab lus zoo sib xws, nrog rau qhov sib txawv tseem ceeb yog tus naj npawb thiab qhov nyuaj ntawm cov zaus bands ua tiav.
Duplexer
Lub duplexer muaj ob lub lim dej uas sib koom ib qho chaw nres nkoj (feem ntau yog ib lub kav hlau txais xov) thiab siv los ua cov haujlwm ntawm kev xa (Tx) thiab txais (Rx) ntawm tib lub cuab yeej. Nws yog tsuas yog siv nyob rau hauv zaus division duplex (FDD) systems los tiv thaiv kev sib nrig sib cuam tshuam los ntawm kev sib cais kis thiab tau txais cov cim. Duplexers yuav tsum muaj kev sib cais siab, feem ntau siab dua 55 dB, kom ntseeg tau tias cov teeb liab kis tsis cuam tshuam rau qhov rhiab heev ntawm tus txais.
Triplexer
Ib lub tripplexer muaj peb lub lim dej uas sib koom ib qho chaw nres nkoj. Nws tso cai rau lub cuab yeej ua cov cim los ntawm peb qhov sib txawv ntau zaus ib txhij thiab feem ntau siv hauv kev sib txuas lus uas yuav tsum tau txhawb nqa ntau zaus bands ib txhij. Tus tsim ntawm triplexer yuav tsum tau xyuas kom meej tias lub passband ntawm txhua lub lim tsis thauj lwm cov lim dej thiab muab kev sib cais txaus kom tsis txhob muaj kev cuam tshuam ntawm cov zaus bands.
Quadplexer
Lub quadplexer muaj plaub lub lim dej uas sib koom ib qho chaw nres nkoj. Nws tso cai rau cov cuab yeej ua cov teeb liab los ntawm plaub qhov sib txawv zaus ib txhij thiab tsim nyog rau cov kev sib txuas lus nyuaj uas yuav tsum tau ua kom muaj txiaj ntsig zoo, xws li cov khoom siv sib xyaw ua ke. Tus tsim complexity ntawm lub quadplexer kuj yog siab heev thiab yuav tsum tau ua kom tau raws li nruj cross-isolation yuav tsum tau kom paub tseeb tias cov teeb liab ntawm lub zaus bands tsis cuam tshuam rau ib leeg.
Qhov tseem ceeb sib txawv
Number of zaus bands: Duplexers ua ob zaus bands, triplexers ua peb zaus bands, thiab quadplexers ua plaub zaus bands.
Tsim complexity: Raws li tus naj npawb ntawm zaus bands nce, qhov tsim complexity thiab kev cais yuav tsum tau nce raws li.
Daim ntawv thov scenarios: Duplexers feem ntau yog siv nyob rau hauv yooj yim FDD systems, thaum triplexers thiab quadplexers yog siv nyob rau hauv advanced kev sib txuas lus systems uas yuav tsum tau txhawb ntau zaus bands ib txhij.
Nkag siab txog hom kev ua haujlwm thiab qhov sib txawv ntawm duplexers, triplexers, thiab quadplexers yog qhov tseem ceeb rau kev tsim thiab ua kom zoo dua kev sib txuas lus wireless. Xaiv hom multiplexer uas tsim nyog tuaj yeem txhim kho qhov kev siv spectrum thiab kev sib txuas lus zoo.
