I-SYN480 315M 433M i-superheterodyne engenantambo ithola ukufinyelela kokuvikeleka kwesiteji ukukhanyisa imojuli yesilawuli kude esifakiwe Isithombe

I-SYN480 315M 433M i-superheterodyne engenantambo ethola ukuphepha kwesiteji sokukhanyisa isilawuli esikude

Incazelo emfushane:

Imojula yokwamukela i-RX480 isebenzisa i-chip ye-SYN480 futhi isekela izindlela zokumodulation ze-ASK ne-OOK. Imojuli yomamukeli ihlanganisa ukuzwela okuphezulu (-107dBm), ukusebenza kwamandla aphansi, nobubanzi obuguquguqukayo obuphezulu (obukhulu kuno-60dB). I-module ithatha i-chip ephezulu yokuhlanganisa, eyakhelwe ngaphambili-ekugcineni okuphansi komsindo weamplifier, i-mixer, isihlungi, i-frequency synthesizer namanye ama-circuits, angakwazi ukwandisa isignali ngezinga eliphezulu.

Ngokwezidingo ezahlukene zohlelo lokusebenza.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici zomkhiqizo
Sekela imodi yemodulation ye-ASK/OOK, thola ukuzwela kufika ku--107dBm;
Imvamisa yokusebenza: 315 MHz, 433.92 MHz, umkhawulokudonsa mayelana ne-±150KHz;
Ububanzi bokufakwa kwamandla kagesi: 3V-5.0V;
Ukukhetha okuhle kanye nekhono lokucindezela imisebe elahlekile, kulula ukudlulisa isitifiketi samazwe ngamazwe se-CE/Fcc;
Ikhono elihle lendawo lokucindezelwa kwemisebe yokudlidliza, amamojula amaningi okwamukela angasebenza ndawonye (okungukuthi, ukudluliswa okukodwa kanye nokwamukela okuningi) futhi ngeke aphazamisane, futhi ibanga elamukelayo ngeke lithinteke lapho lisetshenziswa ndawonye;
Ibanga lokushisa: -40-85℃ lingasebenza ngokujwayelekile ngisho nangaphansi kwezinga lokushisa eliqinile;
Usayizi omncane kakhulu (ungenziwa ngokwezifiso ngokuya ngezidingo zekhasimende).

Ububanzi besicelo
Ukushintsha kwamandla angenantambo, isokhethi
Amakhethini okulawula kude, isilawuli sokufinyelela, izimoto zikagesi
Ukuphepha, uhlelo lokuqapha
Ukulawula igumbi lehhotela
Imikhiqizo yasekhaya ehlakaniphile

Ukuhlelwa kwephakheji nephini
Iphinikhodi) uchungechunge
I-plug-in panel module) uchungechunge
Kuzicelo ezijwayelekile, i-antenna ingasetshenziswa ngokuqondile emakethe izincazelo ezijwayelekile, ngale ndlela elandelayo:
315M uthi
I-antenna core diameter (kuhlanganise nesikhumba) 1.0mm, (ngaphandle kwesikhumba) 0.5mm;
Ubude bentambo yokushisela bungu-17.5mm, ubude bocingo lwesiphetho se-antenna bungu-9.5mm;
Ububanzi be-antenna (kuhlanganise nesikhumba) 5mm;

Ukuphenduka kwenombolo ye-15.
433M uthi
Ubude bentambo yokushisela engu-10mm
Intambo ye-antenna ubude obuphelele obuyi-170mm;
Ukuphenduka kwenombolo ye-15.
Uhlobo oluthuthukisiwe olukhethekile
Uma kudingeka ibanga elide lokuxhumana, i-antenna yohlobo olujwayelekile yohlelo lokusebenza ayikwazi ukuhlangabezana nalo, futhi uthi oluthuthukisiwe lungasetshenziswa ukuthuthukisa ibanga lokwamukela, ngale ndlela elandelayo:
315M uthi
I-antenna core diameter (kuhlanganise nesikhumba) 1.2mm, (ngaphandle kwesikhumba) 0.5mm;
Ubude bezintambo zokushisela buyi-20mm;

I-antenna ephendukayo ububanzi (ngaphandle kwesikhumba) 6.8mm;
Isibalo sokuphenduka okumazombezombe ngu-13, kanti ubude bokujika bungu-23.5mm.
433M uthi
I-antenna core diameter (kuhlanganise nesikhumba) 1.0mm, (ngaphandle kwesikhumba) 0.35mm;
Ubude bezintambo zokushisela buyi-12mm;
I-antenna ephendukayo ububanzi (ngaphandle kwesikhumba) 3.0mm;
Inombolo ejikajikayo ingamajika angama-26 kanti ubude bokujika bungama-36mm.
