Limiter

Lilimiter ke sesebelisoa sa elektronike se sebelisetsoang ho fokotsa boholo ba lets'oao ka har'a mefuta e itseng ho thibela ho tlala kapa ho sotha ha mats'oao.Ba sebetsa ka ho sebelisa phaello e feto-fetohang ho lets'oao le tlang, ho fokotsa bophahamo ba lona ha le feta moeli kapa moeli o reriloeng esale pele.Limiter ke attenuator e itaolang le modulator ea matla.Ha matla a ho kenya a lets'oao a le nyane, ha ho na attenuation.Ha matla a ho kenya a eketseha ho boleng bo itseng, ho fokotseha ho tla eketseha ka potlako.Boleng bona ba matla bo bitsoa "threshold level".

Litšobotsi tsa RF limiter ea rona li kenyelletsa:

1.High speed limiter: e ka arabela ka potlako le ho sebetsana le matšoao a phahameng a maqhubu, e le hore letšoao le bolokoe sebakeng se sireletsehileng.
2.Tlhaloso e tlaase: e ka laola ka katleho boholo ba pontšo, ho etsa bonnete ba hore pontšo e ke ke ea bonahala e sothehile le ho senya.
Litšobotsi tsa 3.Broadband: sekoaelo sa maqhubu 0.03 ~ 18GHz, se ka sebetsana le mefuta e fapaneng ea lipontšo tsa maqhubu.
4.Ho nepahala ho phahameng: boholo ba pontšo bo ka laoloa ka nepo ho netefatsa hore ts'ebetso ea pontšo e nepahetse ka hohle kamoo ho ka khonehang.
5.Tlhahiso e tlase ea matla: matla a 5 ~ 10w ke a mangata, a etsang hore e be molemo haholo lits'ebetsong tsa maqhubu a phahameng tlas'a tšitiso ea phepelo ea motlakase ea mohala.
6.Botsitso bo phahameng: Beam e ka boloka ts'ebetso e tsitsitseng tlas'a liphetoho tsa mocheso le maemo a mang a tikoloho, kahoo e loketse haholo bakeng sa likopo tse rarahaneng.

Tse latelang ke tse ling tsa lits'ebetso tsa limiter:

1.Sireletsa lipotoloho le lisebelisoa: Limiter e ka sebelisoa ho sireletsa lipotoloho le lisebelisoa ho tloha ho li-amplitudes tse phahameng tsa matšoao.Ha lets'oao la ho kenya le feta moeli oa moeli, moeli o tla fokotsa boholo ba lets'oao ka har'a sebaka se sireletsehileng ho thibela ho tlala le ho senyeha ha sesebelisoa.
2. Ts'ebetso ea molumo: Limiter e sebelisoa haholo ts'ebetsong ea molumo.Ka mohlala, ho lisebelisoa tsa ho rekota le ho bapala, limiter e ka sebelisoa ho laola mefuta e mengata ea molumo oa molumo, e le hore boholo ba molumo oa molumo o ka har'a sebaka se amohelehang, ho thibela ho tlala kapa ho sotha ha molumo.
3. Sistimi ea puisano: Ts'ebetsong ea puisano, moeli o ka sebelisoa ho lokisa boholo le mefuta e matla ea lets'oao ho netefatsa hore lets'oao ha le fetise moeli oa karolelano ea lerata nakong ea phetisetso, ho ntlafatsa boleng le ts'epahalo ea puisano.
4. Ts'ebetso ea video: Limiter e boetse e sebelisoa hangata ha ho etsoa video.Ka mohlala, lik'hamera tsa video le mekhoa ea ho shebella, moeli o ka sebelisoa ho laola boholo ba pontšo ea video, e le hore khanya le phapang ea setšoantšo e be ka har'a sebaka se loketseng, ho ntlafatsa ho hlaka le ho bonahala ha setšoantšo.
5. Tekanyo e nepahetseng: Libakeng tse ling tsa tekanyo e nepahetseng, moeli o ka sebelisoa ho laola amplitude ea pontšo ea ho kenya letsoho ho netefatsa ho nepahala le botsitso ba liphetho tsa tekanyo.Ka mohlala, lisebelisoa tsa ho metha ka mokhoa o nepahetseng haholo, moeli o ka qoba liphoso tsa ho lekanya tse bakoang ke matšoao a ho kenya ka ntle ho sebaka.

QualwaveInc. e fana ka li-limiters tse nang le maqhubu a mangata a 0.03 ~ 12GHz, a loketseng bakeng sa mohala, transmitter, radar, laboratori le libaka tse ling.
