Ikoranabuhanga rya RF No Isesengura

Abatungura RF (abagugwa kuri radio) ni ibintu bitoroshye mu muzunguruko wa RF, byagenewe kwimenyereza ibimenyetso, guhuza, no gukwirakwiza amashanyarazi mu bidukikije. Biratandukanye nababisanzwe mubintu biranga byinshi, guhitamo ibintu, hamwe nibishushanyo mbonera, bikaba ngombwa muri sisitemu yitumanaho, radar, ibikoresho byikizamini, nibindi bikoresho, nibindi bikoresho. Iyi ngingo iratanga isesengura ritunganijwe yamahame ya tekiniki, inzira zikoreshwa, ishingiro rigaragara, nuburyo busanzwe.

I. AMAB'amahame ya tekinike
Igenzura ryinshi-riranga parameter ya parasitike
Abahubamo RF bagomba gukomeza imikorere ihamye kumurongo mwinshi (MHZ kuri GHZ), bisaba guhagarika umutima wa kaminuza nubushobozi. Abagogosha basanzwe barwaye inductance na interineti, bigatera gutandukana kwanduza inshuro nyinshi. Ibisubizo by'ingenzi birimo:

Ibikoresho byoroheje / film-film. Imiterere yo kurwanya ishingiro yashizweho (urugero, Tantalum Nitride, Nitr Asloy) binyuze kuri potolililique kugirango ugabanye ingaruka za parasitiki.

Kwipimisha-inshuro nyinshi

Isesengura ryurusomyi (VNN): Kwemeza S-Ibipimo (S11 / S21), Impemu Guhuza, no Gutakaza.

Ubushyuhe bwo kwigana no gusaza: Kwigana ubushyuhe buva mu mbaraga nyinshi ndetse n'igihe kirekire (urugero, amasaha 1.000 yo kwipimisha).

III. INGINGO Z'IBIKURIKIRA
Abatuwe RF bahanganye mu turere dukurikira:

Imikorere myinshi

Parasitics nkeya: Inductance ya parasitike <0.5nh, ubushobozi <0.1pf, kumenyesha impete ihamye kugeza ghz.

Igisubizo cya Broadband: Gushyigikira DC ~ 110GHZ (urugero, mmave bands) kumanota 5G nr na satelite itumanaho.

Imbaraga nyinshi nubuyobozi bwubushyuhe

Ubucucike bw'imbaraga: Kugera kuri 10w / MM²² (urugero, aln restrates), hamwe no kwihanganira impinduramatwara (urugero, 1μw @ 1μs).

Igishushanyo mbonera cya Thermal: Ubushyuhe bwubushyuhe cyangwa imiyoboro ikonjesha kuri sitasiyo ya base na radars-array.

Uburemere bwibidukikije

Ubushyuhe butuje: Kora kuri -55 ℃ kugeza kuri 200 ℃, guhura nibisabwa na Aerospace.

Kurwanya ibirwango & Ikidodo: Ikidodo cya Mil-STD-810G-810G CYIZA CYIZA CYACUTS hamwe na IP67 umukungugu / amazi.

IV. Ibisanzwe bisanzwe
Sisitemu y'itumanaho

5g sitasiyo: Byakoreshejwe muri PA gusohoka guhuza imiyoboro kugirango igabanye VsWR no kuzamura agaciro.

Microwave Backhaul: Ikintu cyibanze cya Attenuator cyo guhindura imbaraga (urugero, 30DB Kwanga).

Radar na ordogon

Imyambarire-Array Radiars: Gukuramo ibitekerezo bisigaye muri T / R MODULE kugirango urinde lnas.

Vi. Umwanzuro
Nk '"abarinzi bucece" ba sisitemu nyinshi-zinshi, abakurambere ba RF bibugarimbano bihuye, amashanyarazi, hamwe no gushikama. Porogaramu zabo zikoresha sitasiyo ya 5G, rased-array radar, amashusho yubuvuzi, na sisitemu yinganda. Hamwe niterambere ryitumanaho na MMwave SemiconduChics, abayoboke ba RF bazahindukira biganisha ku mbaraga nyinshi, kandi ubwenge, bugatangazwa muri sisitemu ikurikiranye.
