RADIOPEREDATChIK

RADIOPEREDATChIK, olatest ba­roi hosil kardani lappishhoi elektrik modulyatsiyakardashuda dar diapazoni radiobasomadho va bad dar namudi mavjhoi elektromagniti (tavassuti antenna) afkandani onho. Radioperedatchik qismi muhimtarini sistemavu tajhizothoe meboshad, ki informatsiyaro dar namudi mavjho irsol mekunad; on dar radioaloqa, televizion, radioshunavoni, radiolokatsiya, radionavigatsiya va digar sohahoi tekh­nika (masalan, nig. Radiomarkazi irsol), inchunin dar tadqiqoti ilmi istifoda meshavad. Radioperedatchikho vobasta ba diapazoni mavjhoi kori (nig. Radiomavjho), iqtidori lappishhoi ba antenna rasondashavanda (to 100 Vt kamiqtidor, az 100 Vt to 10 kVt miyonaiqtidor, az 10 kVt to 1 MVt puriqtidor va besh az 1 MVt favquliqtidor), sohai kor (tele­graf, telefon va gayra), tarzi modulya­tmiya (amplitudavi, basomadi, fazavi va gayra) tainot (aloqa, radioshunavoni lokatsiya, televizioi va gayra), mavqe (statsionari, sayyor) har khel meshavand. Padioperedatchiki odditarin (yakaskadi) az generatori khudangezandae, ki energiyai jarayoni doimi (bazan tagyirobanda)-ro ba egergiyai lappishhoi radiobasomad tabdil medihad, modulyator va manbai tamini energiya iborat ast. Ammo Radioperedatchikhoe, ki dar diapazoni mavjhot detsimetri va daroztar az on kor mekunand, odatan az chand kaskad iboratand, ki har kadom vazifahoi gunogunro ado mekunand. Bo rohi tagyir dodani in yo on parametri Radioperedatchik lappishhoi radiobasomad modu­lyatsiya karda, tavassuti zanjiri aloqa ba antenna, khati aloqai kabeli yo simi doda meshavad.
