Kapangidwe ka Ma Frequency Ogwirizana Bwino
The2025MHz-2110MHz/2210MHz-2300MHz Cavity Diplexerimagwiritsa ntchito njira yolandirira pa 2067.5 MHz ndi pass band ya 2025-2110 MHz; ndi njira yotumizira pa centre frequency ya 2255 MHz ndi pass band ya 2210-2300MHz. Kapangidwe ka njira ziwirizi polekanitsidwa ndi 187.5MHz kamalola kutumiza ndi kulandira nthawi imodzi (ntchito yonse ya duplex) ndi gulu loteteza laling'ono kwambiri lomwe likutayika motero.
kukulitsa kugwiritsa ntchito bwino kwa ma spectral (moyenera) mu LTE ndi 5G NR deployments.

Kutayika Kotsimikizika ndi Kusalala kwa Kuyika

Cavity Diplexer ku Keenlion ili ndi kutayika kwakukulu kwa 0.8 dB m'ma passband ake onse awiri. Ripple ya passband ili pansi pa 0.6 dB kuti chizindikiro chifalikire bwino. Izi zimalola kutumiza kwa chizindikiro cha amplitude koyera, komwe kudzatsimikizira kukhulupirika kwa modulation ya njira zatsopano zosinthira QAM. Mayunitsi ali ndi VSWR ya 1.3:1 kapena kupitirira apo izi zimapangitsa kuti pakhale kutayika pang'ono kwa kubweza.

Chitetezo Chokana Ma Band Ambiri

Cavity Diplexer ya 2025MHz-2110MHz/2210MHz-2300MHz imadziwika ndi mphamvu zokana mawaya osagwiritsidwa ntchito ndi mawaya. Ma channel omwe ali pafupi amapereka 88 dBc yolekanitsidwa pakati pa njira zotumizira ndi zolandirira. Ma band akuluakulu a GNSS amatetezedwa kudzera mu kukana kocheperako kwa 40 dBc pa (1559-1602 MHz (GPS L1)), kukana kocheperako kwa 50 dBc pa (1610-1623 MHz GLONASS), ndi kukana kocheperako kwa 45 dBc pa (1207-1278 MHz GPS L2)). Pankhani ya kukhalapo pakati pa Bluetooth ndi WiFi, imapereka kukana kocheperako kwa 50dBc pa 2482-2500 MHz.

Kupondereza kwa Harmonic, Mphamvu Yogwira Ntchito

Mu Cavity Diplexer, kukhala ndi Harmonic Suppression Yachiwiri ya 70 dBc ndi Harmonic Suppression Yachitatu ya 50 dBc kumachepetsa kuchuluka kwa kusokoneza komwe kumapangidwira ogwiritsa ntchito ena a spectrum. Kuchuluka kwa mafunde okhazikika a 400 watt kumalola kugwiritsa ntchito ma transmitter amphamvu kwambiri a macro base station popanda kuwonongeka kwa kutentha. Zolumikizira zamtundu wa N (doko la antenna lachikazi, ma ports otumizira/olandila amuna) zimapereka kulumikizana kolimba komanso kosatha nyengo ku zingwe zolumikizira zamtundu wa cell.

Kukhazikika kwa Chilengedwe

Cavity Diplexer (2025MHz-2110MHz/2210MHz-2300MHz)Yapangidwa kuti igwire ntchito kutentha kwambiri kuyambira -45°C mpaka +85°C ndipo imaposa miyezo yachikhalidwe ya mafakitale pankhani ya magwiridwe antchito. Mapeto oyamba a aluminiyamu apereka chitetezo chokhalitsa komanso chosawononga dzimbiri popanda kupanga zovuta zina zowonjezera. Mikhalidwe yokhazikika ya kutentha ndi makina imalola kuti magetsi azigwira ntchito bwino mosasamala kanthu komwe akugwiritsidwa ntchito - kuyambira kuchipululu mpaka kumadera akumpoto.

Si Chuan Keenlion Microwave ndi makina ambiri osankhidwa m'makonzedwe a narrowband ndi broadband, okhala ndi ma frequency kuyambira 0.5 mpaka 50 GHz. Amapangidwira kuti azitha kugwiritsa ntchito mphamvu yolowera ya ma watts 10 mpaka 30 mu makina otumizira mawaya 50. Mapangidwe a microstrip kapena stripline amagwiritsidwa ntchito, ndipo amakonzedwa kuti agwire ntchito bwino kwambiri.

Tingathensosinthani RF Cavity Diplexermalinga ndi zomwe mukufuna. Mutha kulowa patsamba losinthira kuti mupereke zofunikira zomwe mukufuna.
