Saldhigyada saldhigga satalaytka

Codsiyada ugu muhiimsan ee anteenooyinka anteenooyinka iyo cod-weynaha ee saldhigyada saldhigga satalaytka waa sida soo socota:

1. Anteeno: Calaamadaha isgaarsiinta satalaytka waxay u baahan yihiin in laga qaado anteenada dhulka ilaa dayax-gacmeedka iyo satalaytka dhulka ku laabanaya. Sidaa darteed, anteelku waa qayb muhiim ah oo ku saabsan gudbinta seenyaalaha, kaas oo diirada saari karta calaamadda hal dhibic isla markaana wanaajin karta xoogga iyo tayada calaamadaha.

2. Amptifier: Digniintu waa la dhigaa inta lagu gudajiro gudbinta, markaa cod-weyne ayaa loo baahan yahay si loo kordhiyo xoogga calaamadda oo ay hubiso in calaamadda ay gaari karto dayax-gacmeedka iyo qaatayaasha dhulka. Awoodda cod-bixinta ee loo adeegsaday saldhigyada saldhiga sare ee isgaadhsiinta guud ahaan waa dhaxalka dhawaqa hoose (LNA), oo leh astaamaha sawaxanka hooseeya iyo faa iidada, taas oo horumarin karta dareenka la helay. Isla mar ahaantaana, cod-weyne sidoo kale waxaa loo isticmaali karaa dhamaadka gudbinta si kor loogu qaado calaamadda si loo gaaro masaafada dheer ee gudbinta. Ka sokow anteenooyinka iyo cod-weynaha, saldhigyada saldhiga satalaytka waxay u baahan yihiin qaybo kale, sida fiilooyinka kale ee RF iyo DF wareejinta, si loo hubiyo gudbinta calaamadaha jilicsan iyo xakamaynta.
