Lisebelisoa tsa RF

About

FMUSER, joalo ka morekisi oa lisebelisoa tsa khaso tsa AM, ka bokhabane ba eona melemo ea litšenyehelo le ts'ebetso ea sehlahisoa, e fane ka tharollo ea khaso ea AM e etelletseng pele indastering ho liteishene tse ngata tse kholo tsa AM lefatšeng ka bophara. Ntle le li-transmitter tse 'maloa tsa matla a phahameng a phahameng a AM a ka tsamaisoang ka nako efe kapa efe, o tla fumana lithuso tse fapaneng tsa ho sebetsa le sistimi e kholo ka nako e le ngoe, ho kenyeletsoa. leka meroalo e nang le matla a fihlang ho 100kW/200kW (1, 3, 10kW e fumaneha hape), ea boleng bo holimo liteko li eme, le lenakana Sistimi ea ho tsamaisana le impedance. Ho khetha tharollo ea khaso ea FMUSER's AM ho bolela hore o ntse o ka haha seteishene se felletseng sa sistimi ea khaso ea AM e sebetsang hantle ka theko e lekantsoeng - e netefatsang boleng, bophelo bo bolelele le ts'epahalo ea seteishene sa hau se pharalletseng.

# 1 FMUSER's Solid-state Loads (Dummy Loads) bakeng sa AM Transmitters

Li-amplifiers tse ngata tsa FMUSER RF, li-transmitter, lisebelisoa tsa motlakase kapa li-modulator li sebetsa ka matla a phahameng haholo le a mahareng. Sena se bolela hore ho ke ke ha khoneha ho hlahloba mekhoa e joalo ka meroalo ea bona e reretsoeng ntle le kotsi ea ho senya mojaro. Ho feta moo, ka matla a phahameng joalo a hlahisoang, li-transmitters tsa maqhubu a mahareng li tlameha ho bolokoa kapa ho lekoa nako e 'ngoe le e 'ngoe, ka hona, teko ea boleng bo phahameng e tlameha ho etsoa seteisheneng sa khaso. Meroalo ea liteko e entsoeng ke FMUSER e kenyellelitse likarolo tsohle tse hlokahalang ka har'a khabinete e le 'ngoe, e lumellang taolo e hole le ho fetoha ha othomathike le ka letsoho - ehlile, sena se ka bolela ho hongata bakeng sa taolo efe kapa efe ea sistimi ea khaso ea AM.

#2 FMUSER's Liteko tsa Mojule

Liteko tsa liteko li etselitsoe haholo ho netefatsa hore na li-transmitters tsa AM li maemong a matle a ho sebetsa kamora tokiso ea "buffer amplifier" le boto ea amplifier ea matla. Hang ha e fetile tlhahlobo, transmitter e ka sebetsoa hantle - sena se thusa ho fokotsa sekhahla sa ho hlōleha le sekhahla sa ho emisa.

#3 FMUSER's AM Antenna Impedance System Matching

Bakeng sa li-antenna tsa AM transmitter, maemo a leholimo a fetohang joalo ka sealuma, pula le mongobo, joalo-joalo ke lintlha tsa bohlokoa tse bakang ho kheloha ha impedance (mohlala, 50 Ω), ke ka lebaka leo ho hlokahalang mokhoa oa ho bapisa le ho ts'oana - ho ts'oanela ts'ebetso ea antenna hape. .

Li-antenna tsa AM hangata li kholo haholo ka boholo ebile li bonolo ho sitisa kheloha, 'me sistimi ea FMUSER e sa amaneng le motho e etselitsoe tokiso e feto-fetohang ea li-antenna tsa khaso ea AM. Hang ha ts'ebetso ea antenna ea AM e kheloha ka 50 Ω, sisteme e ikamahanyang le maemo e tla lokisoa hore e boele e ts'oane le ho sitisa marang-rang a modulation ho 50 Ω, e le ho netefatsa boleng bo holimo ba phetisetso ea mochini oa hau oa AM.
