Ukubonisana okungenantambo – Iphakethe Lemibhobho Engenantambo ye-UHF 1 kuya ku-8 Yesistimu Yokubonisana (550‑980MHz, PLL, Ibanga lika-60m)
Ukucaciswa nemingcele yephakethe lemibhobho eyodwa kuye kweyisishiyagalombili engenazintambo yesistimu yengqungquthela engenazintambo ye-U-section
Ukusebenzisa ibhande lemvamisa le-UHF 550MHz - 980MHz, ukusebenzisa ubuchwepheshe be-PLL frequency synthesis phase-locked loop, imvamisa iyashintshwa, futhi amandla okudlulisa ayashintshwa, kugwenywe ukuphazamiseka kwemvamisa;
Ukulawulwa kwebhasi le-CPU elihlanganisiwe, isibonisi sedijithali se-LCD, ukusebenza okulula, ukusebenza okuhle kakhulu;
Ngokusebenzisa izihlungi ezikhethekile ze-multi-level narrowband high-frequency intermediate-frequency, izimpawu zokuphazamiseka ziyasuswa ngokuphelele.
Ngokwamukela ubuchwepheshe bokunweba ukucindezelwa komsindo, umsindo wehliswe kakhulu futhi ububanzi obunamandla bunwetshiwe.
Inomsebenzi wokucindezela nokunciphisa umsindo wokubuyela emuva, onganciphisa kahle umsindo wokubuyela emuva.
Isamukeli sisebenzisa izigaba eziningi zokukhulisa imvamisa ephezulu, okwenza ukuthi sibe nokuzwela okuphezulu.
Isifunda sokuqapha imisindo eminingi kanye nesistimu yokuqinisekisa amakhodi e-AD hoc ID sithuthukisa ukusebenza kwayo okuqinile okulwa nokuphazamiseka.
Ngokukhetha ama-chip nezingxenye ezisezingeni eliphezulu, umshini ufinyelela ikhwalithi yomsindo enhle kakhulu.
Ibanga elifanele lokusetshenziswa lingamamitha angu-60.
