Waa maxay diplexer-ka godka ku jira?
Qalabka diplexer-ka godka waa qalab aan firfircoonayn oo u oggolaanaya gudbinta iyo soo dhoweynta calaamadaha isku mar hal anteeno iyadoo la kala saarayo xargaha soo noqnoqda ee loo qoondeeyay. Qalabka diplexer-ka godka 891-903mhz/936-948mhz waxaa loo sameeyay inuu bixiyo go'doomin gaar ah oo u dhexeeya xargaha rx (891-903mhz) iyo tx (936-948mhz).

Astaamaha farsamada ee muhiimka ah
Qalabka diplexer-ka godkayaga waxaa loogu talagalay inuu daboolo shuruudaha adag ee nidaamyada isgaarsiinta casriga ah:
