Wideband 100-400MHz Digital LoRa Module

Module ya LoRa yapamwamba (chitsanzo: ZD-PAL-100/400M-50W) yoyambitsidwa ndi ZDTECH ndi njira yolumikizirana opanda zingwe yomwe imaphatikiza magwiridwe antchito apamwamba komanso kudalirika. Mafupipafupi ake ogwiritsira ntchito amapangidwa kuti akhale 100-400MHz, omwe samakwaniritsa zosowa za msika wamakono, komanso amasunga malo kuti awonjezere mtsogolo. Mphamvu yotulutsa mphamvu ya moduleyi ndi yokwera kwambiri mpaka 47 ± 1dBm / 50 ± 1dBm, kuphatikiza phindu la 47 ± 2dB / 50 ± 2dB, kuwonetsetsa chizindikiro champhamvu komanso chokhazikika, potero kumathandizira kutumiza kwakutali.

Kuphatikiza apo, kusinthasintha kwa gulu la module kumayendetsedwa mkati mwa ≤2.0dB, kuwonetsetsa kuti chizindikirocho ndi chapamwamba komanso chokhazikika. The input voltage stand wave ratio (VSWR) ndi ≤1.5, zomwe zikutanthauza kuti module ili ndi magwiridwe antchito abwino kwambiri ndipo imatha kuchepetsa kutayika kwa ma sign. Mphamvu yogwiritsira ntchito ndi DC + 28V yokhazikika, ndipo mphamvu yogwiritsira ntchito sidutsa 5A. Kapangidwe kameneka kakang'ono kameneka kamapangitsa kuti gawoli liziyenda bwino pamapulogalamu ogwiritsira ntchito batri ndikuwonjezera moyo wautumiki wa chipangizocho.

Kuti muthandizire kuphatikizika kwadongosolo ndi kuwongolera, gawoli limapereka chiwongolero cha 3.2V-5V ndi kutseka kwa 0V. Doko la RF lotulutsa limathandizira zolumikizira za SMA kapena N, zomwe zimapangitsa kuti zigwirizane ndi zida zosiyanasiyana za RF. Gawoli liri ndi kutentha kwakukulu kwa ntchito, kuchokera -10 ° C mpaka + 55 ° C, zomwe zimawathandiza kuti azigwira ntchito mokhazikika m'malo osiyanasiyana a chilengedwe, ndipo kutentha kwa yosungirako kumafika -25 ° C mpaka + 65 ° C, kuonetsetsa kuti mankhwala akhoza kupulumuka nyengo yoopsa. kudalirika kochepa.

Pomaliza, gawoli limatha kugwira ntchito mumtundu wa chinyezi cha 5% mpaka 95% popanda condensation, kuwonetsa kuthekera kwake kosunga magwiridwe antchito okhazikika pakusintha kwanyengo. Ponseponse, gawo la ZDTECH's LoRa limapereka njira yabwino komanso yodalirika yolumikizirana opanda zingwe kwanthawi yayitali ndikuchita bwino komanso kugwirizanitsa kwakukulu.
