Ukusebenzisa i-high-precision 16M ye-crystal oscillator ye-industrial, i-frequency error earth 10PPM (-40 ~ 85 °) zonke iimodyuli zethu zihlolwe kwaye zivavanywe ukuqinisekisa ukusebenza kwemodyuli nganye.
Chip inzuzo
I-SI24R1 yi-universal low-power, high-performance 2.4GHZ radio frequency transceiver chip, eyenzelwe izicelo ezingenazintambo ezingenazintambo, i-frequency frequency range ye-2400MHZ-2525MHZ, inkxaso ye-2MBPS, i-1MBPS, i-250KBPS amanani amathathu edatha.
Amandla okuhambisa i-SI24R1 yi + 7DBM (i-adjustable), i-turn-off current yi-1UA kuphela, kwaye ukufumana ukuvakalelwa ngu-83DBM @2MHZ. Kwizicelo zekhadi ezisebenzayo, i-chip ilala ixesha elininzi, ngoko ukusetyenziswa kwamandla ngokubanzi kwe-SI24R1 kuphantsi kakhulu kwaye kunokufikelela ngokulula ngaphezu kweminyaka eyi-3 yexesha lokusebenza.
I-SI24R1 isebenzisa uyilo olusulungekileyo lwasekhaya kunye nenkqubo yokuvelisa, eqinisekisa ukusebenza kunye neendleko zikhuphisana kakhulu.
I-SI24R1 yaveliswa ngobuninzi ngokusesikweni ngo-2012, ngokuhambelana kakuhle kwemveliso, uzinzo oluphezulu, kunye neendleko ezifanelekileyo, kwaye yaphumelela ukuvunywa ngamxhelo mnye kubathengi kwicandelo lolungiselelo.
