868MHz LoraWan Te Whakakahoretanga Teitei Bandpass Cavity tātari e mahi ana mai i te 864-872MHz JX-CF1-864M872M-80S
Whakaahuatanga
80dB High Rejection Bandpass Cavity Filter Mahi mai i 864-872MHz
Ko te tātari RF Bandpass JX-CF1-864M872M-80S i hangaia mo te hoko e Jingxin, kei te whakahaere mai i te 864-872MHz me te roopu paahi o 8MHz. He nui te whakakore i runga i te 80dB @ 721-735MHz, VSWR iti iho i te 1.2, e whakaatuhia ana me te ngaronga whakaurunga iti iho i te 1.0dB, te ripple iti iho i te 0.2dB, me te mana mahi i raro i te 30W. He iti noa te ruri o te 54mm x 54mm x 38mm me nga hononga SMA, ka pania ki te tae ma mo te wa roa, ka taea hoki etahi atu tae peita.
Ka taea e tenei tātari kowhao te mahi mo nga otinga haumaru a te iwi. I te mea ko te kamupene tātari RF, ka taea e Jingxin te whakahoki mai i a koe me te ratonga hoahoa ritenga, he maha atu nga whiriwhiringa kohao bandpass e waatea ana mo to tono. Ma te whakapumautanga, ko nga waahanga hāngū RF katoa mai i Jingxin he 3 tau te whakamana.
