Muna 2020, tichibatsirana neHuawei muChina, tichatora chikamu mukuvaka zviuru zvezviteshi zvenharembozha zvisina waya, pakati pazvo tichapa microstrip power dividers ine mafrequency e0.5/6g uye 1-50g semidziyo inotsigira.
Kuwanda kwemidziyo yenharembozha isina waya kuchabatanidzwa muna 2021, uye huwandu hwese hunotarisirwa kudarika makumi ezviuru zvemidziyo.
Mabhendi efrequency akakodzera kutaurirana nesatellite
Nguva: 2021-10-28
ITU inotsanangura mabhendi ema frequency, ayo anoshandiswa pakutaurirana kwesatellite.
UHF (Ultra High Frequency) kana kuti decimeter wave frequency band, huwandu hwemafrequency i300MHz-3GHz.
Iyi frequency band inoenderana neIEEE UHF (300MHz-1GHz), L (1-2GHz), uye S (2-4GHz) frequency bands.
Mafungu eredhiyo eUHF frequency band ari pedyo nekupararira kwemutsara wekuona, anovharwa nyore nyore nemakomo nezvivakwa, nezvimwewo, uye kudzikira kwekutapurirana kwemhepo mukati meimba kwakakura.
SHF (Super High Frequency) kana kuti centimeter wave frequency band, huwandu hwema frequency i3-30GHz.
Iyi frequency band inoenderana neIEEE S (2-4GHz), C (4-8GHz), Ku (12-18GHz), K (18-27GHz) uye Ka (26.5-40GHz).
Mafungu eDecimeter ane urefu hwemafungu e1cm-1dm, uye hunhu hwawo hwekupararira hwakafanana nemafungu echiedza.
EHF (Extremely High Frequency) kana kuti millimeter wave frequency band, huwandu hwemafrequency i30-300GHz.
Iyi frequency band inoenderana neIEEE's Ka (26.5-40GHz), V (40-75GHz) nedzimwe frequency bands.
Nyika dzakabudirira dzakatanga kuronga kushandisa mabhendi e50/40GHz Q/V pamagedhi ebasa resatellite rakagadziriswa rine simba guru (HDFSS) apo zviwanikwa zveKa-band zviri kuwedzerawo kuoma.
Tinogonawo kugadzirisa zvikamu zveRF passive zvinoenderana nezvamunoda. Munogona kupinda papeji rekugadzirisa kuti mupe zvinodiwa zvamunoda.
