Sichuan Keenlion Microwave Technology Yakhazikitsidwa mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndi omwe amapanga zida za Passive Mircrowave ku Sichuan Chengdu, China.

Timapereka zigawo za mirrowave zogwira ntchito kwambiri ndi ntchito zina zofananira ndi ntchito za microwave kunyumba ndi kunja. Zogulitsazo ndizotsika mtengo, kuphatikiza zogawa mphamvu zosiyanasiyana, zolumikizira zowongolera, zosefera, zophatikizira, ma duplexer, zida zongopanga zokha, zodzipatula komanso zozungulira. Zogulitsa zathu zidapangidwa mwapadera kuti zizitha kusiyanasiyana komanso kutentha kwambiri. Zofotokozera zitha kupangidwa molingana ndi zomwe makasitomala amafuna ndipo zimagwira ntchito pamagulu onse odziwika komanso otchuka omwe ali ndi ma bandwidth osiyanasiyana kuchokera ku DC mpaka 50GHz.

Duplexer

Duplexer ndiye zida zazikulu zogwirira ntchito zakunja zakunja ndi malo otumizirana zinthu, zomwe zimalekanitsa ma siginecha opatsira ndi olandirira, kuwonetsetsa kuti zolandilidwa ndi kutumiza zitha kugwira ntchito moyenera. Zili ndi magulu awiri a zosefera za bandpass za ma frequency osiyanasiyana, kupewa kutumizira ma siginecha amderali kwa wolandila.

Theduplexeramagwiritsidwa ntchito kusuntha kulankhulana ndi kugwira ntchito kuthengo ngati Tower osayang'aniridwa, yomwe imatsimikizira malo ake ogwiritsira ntchito ndi malo ogwira ntchito.

Choyamba, tikukhulupirira kuti duplexer ndi yaying'ono, yopepuka. Pakadali pano, chifukwa cha kuchuluka kwa duplexer ndi zovuta zina zaukadaulo, duplexer yama radio ogwirizira pamanja sananenedwe. Koma kwa malo omwe angaperekedwe mu ma radiotelers a galimoto, magalimoto, ndi zina zotero, komanso palinso mawaya opanda zingwe a telefoni ndi mavuto a kutaya kutentha, kuti akwaniritse zizindikiro zina zaumisiri, duplexer miniaturization ndiyofunikira kwambiri.

Chachiwiri, duplexer iyenera kukhala yosavuta kukhazikitsa, makamaka pakuyika ma duplexer ndi ma radio. Iyenera kukhala yamphamvu, yodalirika, yophatikizika, yokhoza kupirira kukhudzidwa kwina ndi kugwedezeka, makamaka lamya yopanda zingwe yamalo ena. Tikudziwa kuti duplexer wapano nthawi zambiri amagawidwa magawo kuti adziwe zomwe zimafunikira pafupipafupi. Ngati mawonekedwe a duplexer sangasinthike, ndizotheka kupangitsa foni yopanda zingwe kunyozeka, ngakhale cholandila choyaka. Chofunika kwambiri. Kuphatikiza apo, ndizothandiza kwambiri ngati malo osamukirako omwe amakhala ovuta kwambiri, zomwe zimafuna kuti duplexer iwonetsetse kuti kulumikizana kuli bwino mkati mwa kutentha komwe kumayendera. Nthawi zambiri, duplex iyenera kukhala ndi mawonekedwe omveka bwino ogwiritsira ntchito kutentha ndikukhala ndi zizindikiro zokhazikika kutentha kuti zigwirizane ndi zofunikira za makina onse.

 

 

Mawu Oyamba

Duplex wamba imakhala ndi zosefera zisanu ndi chimodzi zosagwirizana ndi mizere, resonant iliyonse imafalikira ndikulandila pafupipafupi. Fyuluta yolandirira imathandizira ma frequency otumizira ndikulepheretsa wolandila zingwe zamagetsi, ndipo fyuluta yotumizira imatulutsa ma frequency olandila. Ma duplexer ena sanalembedwe ndipo amangolandira Low ndi HIGH, monga doublock Low = 450, high = 460, kusonyeza kuti mapeto a LOW akhoza kujowina 450 mega receiver HIGH terminal kuti agwirizane ndi 460 megabyte transmitter, kapena The LOW end ilumikizidwa ku transmitter ya 450 megabyte. The HIGH terminal imalumikizidwa ndi cholandila cha 460 megabyte, ndipo ma frequency otumizira ndi kulandila amatha kusinthidwa, koma ma frequency 460 sangathe kulumikizidwa ndi duplexer 450 megabytes kuti apewe kuwonongeka kwa station ndi duplexer.

 

 

Sankhani

Duplexer iyenera kusinthidwa malinga ndi ma frequency transmitting radio. 400 megabye pafupipafupi kusiyana 10 MHz duplexer ntchito bandiwifi akhoza kuonetsetsa kuti kudzipatula ndi za 90 dB, ndi limodzi pafupipafupi mfundo ali ndi ntchito kudzipatula 120 dB. Pamene pafupipafupi ntchito kuposa duplexer yaiwisi m'lifupi, kufala ndi kulandirira kudzipatula kudzawonjezeka kwambiri, ndipo dera lolandira silikugwira ntchito bwino chifukwa cha kukhudzidwa kwa gawo lopatsirana. Gawo la Amateur radiographing terminal U nthawi zambiri limalandira 5 megabytes Hz, duplexer yomwe imagwiritsidwa ntchito ndi kapangidwe kakang'ono, komwe kumatsimikizira kuti kudzipatula sikutsitsidwa, koma bandwidth yogwira ntchito imachepetsedwa, ndipo ndi 100 kHz. Kuyeserera kwatsimikizira kuti kugwiritsa ntchito duplexer kuli bwino kuposa kugwiritsa ntchito tinyanga ziwiri.

 

Titha kusinthanso magawo a rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
