Iindaba zeShishini

Inkqubo yokulwa nedrone yeMars RF isebenzisa uyilo oluyimodyuli, oludibanisa ngokupheleleyo iindlela zokuchonga, ukuchonga, ukulandelela, kunye neendlela zokuthintela irediyo ukubonelela ngokhuseleko olukhawulezileyo nolusebenzayo lwe-endpoint kwiithagethi ezibalulekileyo. Le nkqubo inamandla okusebenza kuyo yonke imozulu, isantya esiphezulu sempendulo, kunye nokumelana okunamandla nokuhlaselwa koxinzelelo, ilwa ngempumelelo neengozi ezahlukeneyo zedrone, kubandakanya iidrone ezingaqhelekanga kunye neembumbulu.

Iityhubhu zamaza ezihambayo (iiTWT), njengabameli betekhnoloji ye-vacuum electronics, zazikhe zalawula iibhendi ezithile zefrikhwensi kunye namanqanaba amandla. Nangona kunjalo, ii-amplifiers zamandla e-solid state (ii-SSPA), ezinenkqubela phambili kwizixhobo ze-semiconductor, ingakumbi ukuvuthwa kwetekhnoloji ye-gallium nitride (i-GaN), ziyayitshintsha imeko yemarike.

Ii-amplifiers zamandla e-Solid state zenza undoqo kwiinkqubo zanamhlanje ezingenazingcingo, kodwa amandla azo adlula kakhulu 'ukukhulisa isignali'. Njengomvelisi okhethekileyo onamava eminyaka engamashumi amabini kwicandelo le-RF, iMars RF ifanisa ii-amplifiers zamandla e-solid state (SSPA) 'nendlu yamandla' yenkqubo yonke ye-RF. Ngemisebenzi emihlanu ephambili, ifaka amandla abalulekileyo kwiinkqubo ze-radar, zonxibelelwano, kunye ne-elektroniki.

IiNarrowband Amplifiers "ziingcali" ezifuna ukugqwesa kwi-frequency ethile. Kwelinye icala, iiWideband power amplifiers zilungelelaniswa lula "zii-all-rounders." Umahluko ophambili phakathi kweentlobo ezimbini zee-power amplifiers uvela kwiinjongo zazo ezahlukeneyo zoyilo, nto leyo ekhokelela ngokuthe ngqo kwiindlela zazo zobugcisa ezahlukeneyo kunye neempawu zokusebenza. Ngamafutshane, i-narrowband amplifier ifuna "ukugqwesa kwe-single-point," ngelixa ii-wideband power amplifiers zifikelela "ekuhambelaneni okubanzi."

Ukwandisa isignali ye-pulse kwahlukile kakhulu ekwandiseni isignali ye-wave eqhubekayo. Umngeni ophambili ulele kubuchule be-amplifier bokutshintsha ngokungenamthungo ukusuka "ekucimeni" ukuya "kumandla apheleleyo" kunye nokubuyela "ekucimeni" ngaphakathi kwe-nanoseconds okanye nakwii-picoseconds, ukugcina ukuthembeka okupheleleyo kwimo ye-pulse kulo lonke eli nkqubo. Nakuphi na ukuphambuka komzuzu, okufana nokuthambekela okuphezulu, ukudubula ngaphezulu, okanye ukukhala, kuya kuguqulela ngokuthe ngqo kwi-target range engacacanga, ukuncipha kwesisombululo, okanye iimpazamo ze-bit kumakhonkco onxibelelwano ngaphakathi kwenkqubo ye-radar. I-Mars RF, isebenzisa ubuchule bayo obunzulu kweli candelo, ichaza indlela yokufezekisa ukwandiswa kwesignali ye-pulse engenasiphazamiso kwaye izisa izisombululo eziphambili.

Kwiinkqubo zanamhlanje zerediyo (RF) ezifana nonxibelelwano olungenazingcingo, ukufunyanwa kweradar, kunye neendlela zokuthintela ze-elektroniki, ii-amplifiers, ingakumbi ii-power amplifiers (PAs), zidlala indima ebalulekileyo nebalulekileyo. Njenge "ntliziyo" yenkqubo, zibonelela ngamandla abalulekileyo kuyo yonke ikhonkco yesignali, zimisela ngokuthe ngqo uluhlu lonxibelelwano, ukuchaneka kokufunyanwa, kunye nokuthembeka kwenkqubo.

Kule mihla yedijithali edibeneyo kwihlabathi liphela, unxibelelwano lwesathelayithi ludlala indima ebalulekileyo ekudluleni kwimida yejografi. Embindini wale nxalenye yomhlaba inzima, iiHigh Power Amplifiers (HPA) zidlala indima engenakutshintshwa nebalulekileyo - zisebenza "njengeentambo zelizwi eziqinileyo" zenkqubo yonke yonxibelelwano lwesathelayithi, ziqinisekisa ukuba imiqondiso yomhlaba inokufikelela kwisathelayithi ezikumawakawaka eekhilomitha kude ngokucacileyo nangokuzinzileyo.

Kwicandelo lee-amplifiers zamandla erediyo, ukhetho lwetekhnoloji yezinto eziphathekayo luchaphazela ngokuthe ngqo imida yokusebenza kwenkqubo. Okwangoku, iiGaAs (Gallium Arsenide) kunye neGaN (Gallium Nitride), njengeetekhnoloji ezimbini eziphambili ze-semiconductor, zidlala indima engenakutshintshwa kwiinkqubo zanamhlanje ezingenazingcingo ngenxa yeenzuzo zazo zokusebenza ezizodwa.

Kwimimandla yanamhlanje ephuhla ngokukhawuleza yonxibelelwano olungenazingcingo, i-aerospace, kunye netekhnoloji yokhuselo, utshintsho lwetekhnoloji olukhokelwa yisayensi yezinto luyaqhubeka ngokuzolileyo. Ii-amplifier zeGallium nitride (GaN), njengabasunguli kwicandelo lamandla erediyo (RF), ziphinda zichaze imigangatho yobugcisa yee-amplifier zamandla ngokusebenza kwazo okuphezulu.

Kwimimandla yetekhnoloji yanamhlanje efana nonxibelelwano lwe-5G, ukufunyanwa kwe-radar, kunye nemfazwe ye-elektroniki, ii-RF power amplifiers zidlala indima ebalulekileyo. Njenge "ntliziyo yamandla" yenkqubo engenazingcingo, umgaqo wazo wokusebenza uchaphazela ngokuthe ngqo imida yokusebenza kwenkqubo yonke. Namhlanje, siza kujonga imigaqo yobugcisa ephambili yee-RF power amplifiers, sityhile indlela eziguqula ngayo imiqondiso ebuthathaka ibe ngamandla e-RF anamandla.
