Sichuan Keenlion Microwave Technology——Mokopanyi

Sichuan Keenlion Microwave Technology E Thehiloe ka 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ke moetsi ea ka sehloohong oa likarolo tsa Passive Mircrowave Sichuan Chengdu, Chaena.

Re fana ka lisebelisoa tsa mirrowave tse sebetsang hantle haholo le lits'ebeletso tse amanang le tsona bakeng sa lits'ebetso tsa microwave lapeng le kantle ho naha. Lihlahisoa li na le litšenyehelo tse ngata, ho kenyelletsa le likarohano tse fapaneng tsa matla, li-couplers tse tataisang, li-filters, li-componder, li-duplexer, likaroloana tse ikhethileng, li-isolators le li-circulator. Lihlahisoa tsa rona li etselitsoe ka ho khetheha maemo a fapaneng a feteletseng le mocheso. Litlhaloso li ka etsoa ho latela litlhoko tsa bareki 'me li sebetsa ho lihlopha tsohle tse tloaelehileng le tse tsebahalang tse nang le li-bandwidth tse fapaneng ho tloha ho DC ho ea ho 50GHz.

Sistimi ea puisano ea mehala e se nang mohala, mosebetsi o ka sehloohong oa motsoako ke ho kopanya matšoao a mangata a li-band le ho a ntša tsamaisong e tšoanang ea kabo ea ka tlung.

Ts'ebetsong ea boenjiniere, marang-rang a 800MHz C, marang-rang a 900MHz G kapa maqhubu a mang a fapaneng a hloka ho hlahisoa ka nako e le 'ngoe. U sebelisa komporo, sete ea sistimi ea kabo ea ka tlung e ka sebetsa ho CDMA frequency band, GSM frequency band kapa lihlopha tse ling tsa frequency ka nako e le 'ngoe.

Ka mohlala, tsamaisong ea li-antenna tsa seea-le-moea, matšoao a ho kenya le ho tsoa a lihlopha tse 'maloa tse fapaneng tsa maqhubu (joalo ka 145mhz le 435mhz) a kopantsoe ka ho kopanya, ebe o hokahanngoa le seteishene sa seea-le-moea se nang le sefepi, se sa bolokeng feela se fepa, empa hape se qoba bothata ba ho fetola li-antenna tse fapaneng.

Mokopanyi hangata o sebelisoa qetellong ea phetisetso. Mosebetsi oa eona ke ho kopanya mats'oao a mabeli kapa ho feta a RF a rometsoeng ho tsoa ho li-transmitter tse fapaneng ho ea ho e le 'ngoe ebe o li romella lisebelisoa tsa RF tse fetisoang ke antenna, ha o ntse o qoba tšebelisano lipakeng tsa matšoao a boema-kepe bo bong le bo bong.

Li-combiners hangata li na le likou tse peli kapa ho feta tsa ho kenya le kou e le 'ngoe feela ea tlhahiso. Ho itšehla thajana ke letšoao la bohlokoa la ho hlalosa bokhoni ba lipontšo tse peli hore li se ke tsa ama e mong. Ka kakaretso e hlokahala ho feta 20dB.

Motsoako oa borokho oa 3dB o na le likou tse peli tsa ho kenya le likou tse peli tse hlahisoang, joalo ka ha ho bonts'itsoe ho Setšoantšo sa 2. Hangata e sebelisoa ho kopanya maqhubu a mabeli a sephethephethe a se nang mohala le ho a fepa ka har'a li-antenna kapa mokhoa oa ho aba. Haeba ho sebelisoa boema-kepe bo le bong feela, boema-kepe bo bong bo tlameha ho hokahanngoa le mojaro oa 50W. Ka nako ena, ho na le tahlehelo ea 3dB ka mor'a hore letšoao le kopane. Ka linako tse ling likou ka bobeli li hloka ho sebelisoa, kahoo ha ho na moroalo ebile ha ho tahlehelo ea 3dB.

Kopanya ho amohela le ho romelloa ha lets'oao la selefounu ho lenakana le le leng. Tsamaisong ea GSM, hobane transceiver ha e be ka nako e le 'ngoe, selefouno e ka siea duplexer bakeng sa ho arola transceiver,' me e sebelise feela mochine o bonolo oa transceiver ho kopanya ho romela le ho amohela lipontšo ka har'a antenna e le 'ngoe ntle le ho kena-kenana.

Bakeng sa potoloho e amohelang, antenna e amohela lets'oao, e kena mocha o amohelang ka sehokelo, e kopanya le lets'oao la oscillator ea lehae (ke hore, lets'oao le amoheloang la VCO le hlahisoang ke frequency synthesizer), e fetola lets'oao la maqhubu a phahameng hore e be lets'oao la maqhubu a mahareng, ebe quadrature e theola lets'oao ho hlahisa matšoao a I le Q a amohetseng; Ebe GMSK (Gaussian filter minimal frequency shift keying) e etsoa ho fetolela lets'oao la analog hore e be lets'oao la dijithale, ebe le romelloa ho yuniti ea ts'ebetso ea baseband.

Bakeng sa potoloho ea phetisetso, karolo ea baseband e romela molatsoana oa data oa TDMA (ka sekhahla sa 270.833kbit / s) bakeng sa modulation ea GSMK ho theha matšoao a I le Q, a ntan'o romelloa ho transmission up converter bakeng sa modulation ho frequency frequency band. Kamora ho holisoa ha matla, transmitter e e romella ka antenna.
