Sekoti sa diplexer ke eng?
cavity diplexer ke sesebediswa se sa sebetseng se dumellang phetiso le kamohelo ya matshwao ka nako e le nngwe hodima antenna e le nngwe ka ho arola di-frequency band tse kgethilweng. cavity diplexer ya rona ya 891-903mhz/936-948mhz e entswe ka boqapi ho fana ka karohano e ikgethang pakeng tsa di-rx (891-903mhz) le tx (936-948mhz).

Likarolo tsa bohlokoa tsa tekheniki
diplexer ea rona ea cavity e etselitsoe ho fihlela litlhoko tse boima tsa litsamaiso tsa puisano tsa sejoale-joale:
• maqhubu a setsi sa rx: 897mhz ±1mhz
• maqhubu a bohareng ba tx: 942mhz ±1mhz
• tahlehelo ea ho kenya: ≤1db ho pholletsa le lihlopha ka bobeli
• karolelano ea maqhubu a emeng a motlakase (vswr): ≤1.3:1
• ho hana: ≥65db pakeng tsa lihlopha
• ho se inehele: 50 ohms
• lihokelo: sma-female likoung tsohle
• Matla a ho sebetsa: 10w pele, 2w morao
• mocheso o sebetsang: -20°c ho isa ho +65°c
• thepa: aluminium e nang le qetello ea pente e ntšo

Ke eng e khethollang diplexer ea rona ea cavity?
• tlhahiso e nepahetseng: fektheri ea rona ea lilemo tse 20 e Chengdu e hlahisa diplexer ka 'ngoe ka taolo e matla ea boleng.
• ho etsa hore odara e be ea hau: re fana ka liphetoho tsa maqhubu, liphetoho tsa sehokelo, le li-bracket tse hokeloang ka mokhoa o ikhethileng.
• ho romelloa ka potlako: disampole li romeloa ka hare ho lihora tse 48, 'me liodara tse tloaelehileng li phethahatsoa ka matsatsi a 21.
• tšehetso ea litsebi: sehlopha sa rona se fana ka thuso ea tekheniki ho tloha moralo ho isa ts'ebetsong.

See se ka thusa sistimi ea hau joang?
diplexer ya cavity e thusa ho ntlafatsa tshebediso ya antenna le ho thibela tshitiso ya matshwao ho:
• puisano ea gsm-r le ea literene
• marangrang a pmr le a polokeho ea sechaba
• lits'ebetso tsa iot le m2m
ikopanye le rona kajeno ho ithuta haholoanyane ka rona891-903mhz/936-948mhz cavity diplexerle kamoo e ka ntlafatsang meralo ea hau ea puisano.
