Nhau dzeIndasitiri

Sisitimu yeMars RF inodzivirira madrone inoshandisa dhizaini yakarongeka, inobatanidza zvizere nzira dzekuona, kuziva, kuteedzera, uye nzira dzekudzivirira mafrequency eredhiyo kuti dzipe dziviriro ye endpoint nekukurumidza uye inoshanda kune zvinangwa zvakakosha. Sisitimu iyi ine kugona kushanda mumamiriro ese ekunze, kumhanya kwemhinduro nekukurumidza, uye kuramba kwakasimba pakurwiswa kwe saturation, ichibudirira kurwisa njodzi dzakasiyana-siyana dzemadrone, kusanganisira madrone rimwe chete nemaspurts.

Machubhu ekufamba emafungu (TWTs), semumiriri wetekinoroji yemagetsi evacuum, aimbove ari pamusoro pemabhendi efrequency chaiwo uye mazinga esimba. Zvisinei, ma amplifiers esimba re solid state (SSPAs), ane kufambira mberi muzvinhu zve semiconductor, kunyanya kukura kwetekinoroji ye gallium nitride (GaN), ari kuchinja mamiriro emusika.

Ma-amplifiers emagetsi e-solid state ndiwo musimboti wemasisitimu emazuva ano asina waya, asi kugona kwawo kunopfuura kungo "signal amplification". Semugadziri ane hunyanzvi hwemakumi maviri emakore muRF domain, Mars RF inofananidza ma-amplifiers emagetsi e-solid state (SSPA) ne "powerhouse" yeRF system yese. Kuburikidza nemabasa mashanu akakosha, inoisa simba rakakosha mu radar, kutaurirana, uye masisitimu emagetsi ekudzivirira.

MaNarrowband Amplifiers "vatambi vehunyanzvi" vanotsvaga kugona kwepamusoro-soro panguva yakatarwa. MaWideband power amplifiers, kune rumwe rutivi, anochinjika zviri nyore "kutenderera." Musiyano mukuru pakati pemhando mbiri dzemapower amplifiers unobva pazvinangwa zvavo zvakasiyana zvekugadzira, izvo zvinotungamira zvakananga kune nzira dzavo dzakasiyana dzehunyanzvi uye hunhu hwekushanda. Zvichitaurwa zviri nyore, narrowband amplifier inotsvaga "single-point excellence," nepo mawideband power amplifiers achiwana "kuenderana kwakafara."

Kuwedzera chiratidzo chepulse kwakasiyana zvikuru nekuwedzera chiratidzo chewave chinoenderera mberi. Dambudziko guru riri mukukwanisa kweamplifier kuchinja zviri nyore kubva pa "kudzima" kuenda ku "full power on" uye kudzokera ku "kudzima" mukati me nanoseconds kana kunyange picoseconds, kuchengetedza kuvimbika kwakakwana kuchimiro chepulse mukati mekuita uku. Chero kukanganiswa kweminiti, senge top tilt, overshoot, kana ringing, kuchashandura zvakananga mukusanzwisisika kwenzvimbo yakatarwa, resolution yakaderera, kana zvikanganiso zvebit mu communication links mukati me radar system. Mars RF, ichishandisa hunyanzvi hwayo hwakadzama mundima iyi, inotsanangura maitiro ekuwana kuwedzeredzwa kwechiratidzo chepulse chisina kukanganiswa uye inounza mhinduro dzepamusoro.

Mumasystem emazuva ano eredhiyo (RF) akadai sekutaurirana pasina waya, kuona radar, uye nzira dzemagetsi dzekudzivisa, ma amplifiers, kunyanya ma amplifiers esimba (PAs), anoita basa rinokosha uye rinokosha. Kufanana ne "moyo" wesystem, anopa simba rakakosha kune cheni yese yesignali, zvichiratidza zvakananga huwandu hwekutaurirana, kururama kwekuona, uye kuvimbika kwesystem.

Munguva yanhasi yedhijitari yakabatana pasi rose, kutaurirana kwesetiraiti kunoita basa guru mukupfuura miganhu yenzvimbo. Pakati pechikamu ichi chakaoma chepasi, High Power Amplifiers (HPA) inoita basa risingatsiviwi uye rakakosha - ichiita se "tambo dzezwi dzakasimba" dzehurongwa hwese hwekutaurirana kwesetiraiti, ichiva nechokwadi chekuti zviratidzo zvepasi zvinogona kusvika kumasetiraiti ari kure nemakiromita makumi ezviuru zviri kure zvakajeka uye zvakadzikama.

Mundima yema amplifiers emagetsi eredhiyo, sarudzo yetekinoroji yezvinhu inokanganisa zvakananga miganhu yekushanda kwesystem. Parizvino, GaAs (Gallium Arsenide) neGaN (Gallium Nitride), sematekinoroji maviri makuru e semiconductor, anoita mabasa asingatsiviwi mumasisitimu emazuva ano asina waya nekuda kwezvakanaka zvawo zvekushanda.

Muminda yanhasi iri kukura nekukurumidza yekutaurirana pasina waya, ndege, uye tekinoroji yekudzivirira, shanduko yetekinoroji inotungamirwa nesainzi yezvinhu iri kuitika chinyararire. Gallium nitride (GaN) amplifiers, sevanhu vatsva mumunda wesimba remafrequency eredhiyo (RF), vari kutsanangura patsva mwero wetekinoroji yemagetsi emagetsi nekushanda kwavo kwepamusoro.

Muminda yetekinoroji yepamusoro-soro yakadai sekutaurirana kwe5G, kuona radar, uye hondo yemagetsi, maRF power amplifiers anoita basa rinokosha. Se "moyo wesimba" wesystem isina waya, musimboti wekushanda kwavo unokanganisa zvakananga miganhu yekushanda kwesystem yese. Nhasi, tichaongorora misimboti yehunyanzvi yeRF power amplifiers, tichiratidza kuti vanoshandura sei masaini asina simba kuita simba reRF rine simba.
