Rtduroid5880 high frequency laminate ho tloha Rogers
Rogers5880 high frequency laminate series adopts PTFE composite reinforced glass fiber. Li-microfiber tsena li shebane le lipalo-palo ho eketsa melemo ea ho fumana fiber le ho fana ka tataiso ea bohlokoa ka ho fetisisa bakeng sa baetsi ba potoloho le lits’ebetso tsa ho qetela. The dielectric constant of these high-frequency laminates is the lowest of all products , ‘me tahlehelo e tlaase ea dielectric e etsa hore e tšoanelehe bakeng sa lits’ebetso tse phahameng-frequency / broadband moo ho hasana le tahlehelo li lokelang ho fokotsoa. Ka lebaka la ho monya ha eona metsi a tlase haholo, rtduroid5880 e loketse haholo ho sebelisoa tikolohong ea mongobo o phahameng.

Ba na le tahlehelo e tlase haholo ea motlakase bakeng sa thepa efe kapa efe e matlafalitsoeng ea PTFE, hape ba na le monyetla o tlase haholo oa mongobo mme ke isotropic. Li na le litšobotsi tse tšoanang tsa motlakase ka makhetlo a mangata. High frequency rtduroid5880 e sebelisoa ho lifofane tsa khoebo, microstrip le stripline circuits, millimeter wave system applications tse sebelisoang ho radar ea sesole, li-antenna tsa missile system, mananeo a seea-le-moea a dijithale le tse ling.
