Amakuru y'inganda

Sisitemu yo kurwanya indege zitagira abapilote ya Mars RF ikoresha igishushanyo mbonera cya modular, ihuza neza uburyo bwo kumenya, kumenya, gukurikirana, no kurwanya amajwi ya radiyo kugira ngo itange uburinzi bwihuse kandi bunoze ku bintu by’ingenzi. Sisitemu ifite ubushobozi bwo gukora mu bihe byose, umuvuduko mwinshi cyane wo gusubiza, no kurwanya ibitero bikomeye, ikarwanya neza ibitero bitandukanye bya drone, harimo drone imwe n’imbunda nini.

Imiyoboro y'amashanyarazi igendanwa (TWTs), nk'iy'ikoranabuhanga rya elegitoroniki rikoresha amashanyarazi, yigeze kuba iy'ingenzi mu miyoboro yihariye y'amashanyarazi n'urwego rw'ingufu. Ariko, amplifiers za state power amplifier (SSPAs), hamwe n'iterambere mu bikoresho bya semiconductor, cyane cyane iterambere ry'ikoranabuhanga rya gallium nitride (GaN), ririmo guhindura imiterere y'isoko.

Imashini zitera imbaraga za “Solid state power amplifiers” ni zo zigize inkingi ya sisitemu zigezweho zikoresha insinga, nyamara ubushobozi bwazo burenze kure “kuzamura amajwi” gusa. Nk'inzobere mu gukora imashini zifite uburambe bw'imyaka makumyabiri mu bijyanye na RF, Mars RF igereranya imashini zitera imbaraga za “solid state power amplifiers” (SSPA) n'imashini zitera imbaraga za sisitemu yose ya RF. Binyuze mu mirimo itanu y'ingenzi, ishyira ingufu z'ingenzi muri sisitemu za “radar”, itumanaho, n'izikoresha ikoranabuhanga.

Amplifaya za Narrowband ni "abakinnyi b'umwuga" baharanira ubuhanga ku nshuro runaka. Amplifaya za Wideband, ku rundi ruhande, zirushaho kuba nziza "ku buryo bwose." Itandukaniro ry'ibanze hagati y'ubwoko bubiri bwa amplifaya z'amashanyarazi rituruka ku ntego zazo zitandukanye, ibyo bigatuma inzira zazo zitandukanye za tekiniki n'imikorere. Muri make, amplifaya za narrowband ziharanira "ubuhanga bwa single-point", mu gihe amplifaya za wideband zigera ku "guhuza kwagutse."

Kongera ubwiza bw'ikimenyetso cy'ingufu bitandukanye cyane no kongera ubwiza bw'ikimenyetso cy'ingufu zihoraho. Ikibazo nyamukuru kiri mu bushobozi bwa amplifier bwo guhindura mu buryo butaziguye kuva kuri "kuzimya" ukajya kuri "gutanga imbaraga zose" no gusubira kuri "kuzimya" mu masegonda make cyangwa ndetse na picoseconds, igakomeza kuba inyangamugayo ku miterere y'ingufu muri iki gikorwa. Guhindura imiterere y'umunota, nko kuzamuka hejuru, gushyuha cyane, cyangwa kuringa, bizahindura mu buryo butaziguye imiterere y'aho intego iherereye, kugabanya ubushobozi bwo gupima, cyangwa amakosa ya bit mu miyoboro y'itumanaho muri sisitemu ya radar. Mars RF, ikoresheje ubuhanga bwayo bwimbitse muri uru rwego, isobanura uburyo bwo kugera ku kongera ubwiza bw'ikimenyetso cy'ingufu zidafite ingufu kandi ikanatanga ibisubizo bigezweho.

Muri sisitemu za none za radiyo (RF) nko mu itumanaho ridafite insinga, gupima radar, no kurwanya ikoranabuhanga, amplifiers, cyane cyane amplifiers z'amashanyarazi (PAs), zigira uruhare runini kandi rw'ingenzi. Kimwe n' "umutima" w'iyi sisitemu, zitanga imbaraga z'ingenzi ku ruhererekane rw'ibimenyetso byose, zigena mu buryo butaziguye urwego rw'itumanaho, uburyo bwo kumenya neza, n'uburyo sisitemu yizewe.

Muri iki gihe cy’ikoranabuhanga rihuriweho ku isi, itumanaho rya satelite rifite uruhare runini mu kurenga imbibi z’ubutaka. Mu mutima w’iki gice cy’ubutaka kigoye, High Power Amplifiers (HPA) igira uruhare rudasimburwa kandi rw’ingenzi - ikora nk' "imigozi ikomeye y'ijwi" ya sisitemu yose y’itumanaho rya satelite, igenzura ko ibimenyetso byo ku butaka bishobora kugera kuri satelite ziri mu birometero ibihumbi mirongo uvuye aho iherereye neza kandi neza.

Mu rwego rwo gukoresha amplifiers z’amashanyarazi zikoresha radiyo, guhitamo ikoranabuhanga ry’ibikoresho bigira ingaruka ku buryo butaziguye ku bushobozi bw’iyi sisitemu. Muri iki gihe, GaAs (Gallium Arsenide) na GaN (Gallium Nitride), nk’ikoranabuhanga rikuru rya semiconductor, bigira uruhare rudasimburwa muri sisitemu zigezweho zikoresha insinga bitewe n’inyungu zazo zidasanzwe mu mikorere.

Mu ishami ry’itumanaho rikoresha insinga, ikoranabuhanga ryo mu kirere, n’ikoranabuhanga ryo mu rwego rw’umutekano riri gutera imbere vuba muri iki gihe, impinduramatwara mu ikoranabuhanga iyobowe n’ubumenyi bw’ibikoresho irimo gutangira bucece. Gallium nitride amplifiers (GaN), nk’abahanga mu guhanga udushya mu bijyanye n’ingufu za radiyo (RF), barimo kuvugurura amahame ya tekiniki ya amplifiers z’amashanyarazi bitewe n’imikorere yazo ihebuje.

Mu ikoranabuhanga rigezweho nko mu itumanaho rya 5G, gupima radar, no kurwana mu buryo bw'ikoranabuhanga, amplifiers za RF zigira uruhare runini. Nk' "umutima w'imbaraga" wa sisitemu idafite insinga, ihame ry'imikorere yazo rigira ingaruka ku buryo butaziguye ku bushobozi bwa sisitemu yose. Uyu munsi, turaza gusuzuma amahame y'ingenzi ya tekiniki ya amplifiers za RF power, tugahishura uburyo zihindura ibimenyetso bidakomeye mo ingufu zikomeye za RF.
