Ukulungiswa kwamaphutha okuhle kakhulu kwe-RF
Ibanga elilinganiselwe 240m (indawo ecacile nevulekile)
Ukusebenzisa i-crystal oscillator yezimboni ye-16M enembayo ephezulu, iphutha lemvamisa yomhlaba 10PPM (-40 ~ 85 °) wonke amamojula ethu ayahlolwa futhi ahlolwe ukuze kuqinisekiswe ukusebenza kwemojula ngayinye.
Inzuzo ye-chip
I-SI24R1 iyi-chip yomhlaba wonke enamandla aphansi, esebenza kahle kakhulu engu-2.4GHZ, eyenzelwe izinhlelo zokusebenza ezingenazintambo ezinamandla aphansi, uhla lwemvamisa yokusebenza engu-2400MHZ-2525MHZ, usekelo lwe-2MBPS, 1MBPS,250KBPS amanani amathathu wedatha.
Amandla okudlulisa we-SI24R1 ngu-+7DBM (ayalungiseka), i-curtain off current ingu-1UA kuphela, futhi ukuzwela kokwamukela kungu-83DBM @2MHZ. Kuzinhlelo zokusebenza zamakhadi asebenzayo, i-chip ilala isikhathi esiningi, ngakho-ke ukusetshenziswa kwamandla okuphelele kwe-SI24R1 kuphansi kakhulu futhi kungafinyelela kalula ngaphezu kweminyaka engu-3 yesikhathi sokusebenza.
I-SI24R1 isebenzisa umklamo wasekhaya omsulwa kanye nenqubo yokukhiqiza, eqinisekisa ukusebenza kanye nezindleko kuncintisana kakhulu.
I-SI24R1 yakhiqizwa ngobuningi ngokusemthethweni ngo-2012, inokungaguquguquki okuhle komkhiqizo, ukuzinza okuphezulu, futhi iyonga, futhi yazuza ukuqashelwa ngazwi linye kumakhasimende emkhakheni wokulungiselela.
