Iyo CDU01427M3800M4310F kubva kuConcept Microwave iIP67 Cavity Combiner ine mapassbands kubva 1427-2690MHz uye 3300-3800MHz ine Low PIM ≤-156dBc@2*43dBm. Iyo ine kurasikirwa kwekuisa isingasviki 0.25dB uye yekuzviparadzanisa inodarika 60dB. Inowanikwa mune module inoyera 122mm x 70mm x 35mm. Iyi RF cavity musanganisi dhizaini inovakwa ne4.3-10 majoini ayo ari echikadzi. Zvimwe zvigadziriso, zvakadai sepassband yakasiyana uye yakasiyana-siyana yekubatanidza inowanikwa pasi pemhando dzakasiyana dzemhando.
Low PIM inomirira kuti "Low passive intermodulation." Inomiririra zvigadzirwa zve intermodulation zvinogadzirwa kana maviri kana anopfuura masaini achifamba nemuchina unoshanda usina mutsara zvivakwa. Passive intermodulation inyaya yakakosha mukati meiyo cellular indasitiri uye yakaoma zvakanyanya kugadzirisa. Mumaserura ekutaurirana masisitimu, PIM inogona kukonzeresa uye inoderedza manzwiro evanogamuchira kana kuti inogona kutadzisa kutaurirana zvachose. Kuvhiringidza uku kunogona kukanganisa sero rakaigadzira, pamwe chete nevamwe vanogamuchira vari pedyo.
