CDU01427M3800M4310F ho tloha Concept Microwave ke IP67 Cavity Combiner e nang le li-passbands ho tloha 1427-2690MHz le 3300-3800MHz le Low PIM ≤-156dBc@2 * 43dBm . E na le tahlehelo ea ho kenya ka tlase ho 0.25dB le ho itšehla thajana ho fetang 60dB. E fumaneha ka mojulung o lekanyang 122mm x 70mm x 35mm. Moralo ona oa motsoako oa RF cavity o hahiloe ka lihokelo tse 4.3-10 tseo e leng bong ba basali. Litlhophiso tse ling, joalo ka li-passband tse fapaneng le sehokelo se fapaneng li fumaneha tlasa linomoro tse fapaneng tsa mohlala.
Low PIM e emetse "Low passive intermodulation." E emela lihlahisoa tsa intermodulation tse hlahisoang ha lipontšo tse peli kapa ho feta li feta ka sesebelisoa se nang le thepa e sa tloaelehang. Phapanyetsano e sa sebetseng ke taba ea bohlokoa indastering ea li-cellular mme ho thata haholo ho e rarolla. Litsamaisong tsa puisano tsa lisele, PIM e ka baka tšitiso mme e tla fokotsa kutlo ea moamoheli kapa e ka thibela puisano ka botlalo. Tšitiso ena e ka ama sele e e entseng, hammoho le baamoheli ba bang ba haufi.
