ʻO SYN480 315M 433M superheterodyne uea e loaʻa ana i ka palekana i ke kahua kukui uila mamao

ʻO ka wehewehe pōkole:

Hoʻohana ka module loaʻa RX480 i ka chip SYN480 a kākoʻo i nā ʻano modulation ASK a me OOK. Hōʻike ka module receiver i ka ʻike kiʻekiʻe (-107dBm), ka hana haʻahaʻa haʻahaʻa, a me kahi pae hoʻoikaika kiʻekiʻe (ʻoi aku ma mua o 60dB). Hoʻohana ka module i ka chip hoʻohui kiʻekiʻe, kūkulu ʻia i ka mua-hope haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, mixer, kānana, frequency synthesizer a me nā ʻāpana ʻē aʻe, hiki ke hoʻopaʻa i ka hōʻailona i ka palena kiʻekiʻe.

E like me nā koi noi like ʻole.

Kākoʻo i ke ʻano modulation ASK/OOK, loaʻa ka naʻau a hiki i -107dBm;
Ka pinepine hana: 315 MHz, 433.92 MHz, bandwidth e pili ana i ± 150KHz;
Ka mana hoʻokomo puʻe uila: 3V-5.0V;
ʻO ka koho maikaʻi a me ka hiki ke hoʻopau i ka radiation, maʻalahi ke hele i ka palapala hōʻoia honua CE/Fcc;
ʻO ka hiki ke hoʻopau i ka radiation vibration kūloko maikaʻi, hiki ke hana like nā modula loaʻa he nui (ʻo ia hoʻi, ka hoʻouna hoʻokahi a me ka hoʻokipa lehulehu) a ʻaʻole e hoʻopilikia kekahi i kekahi, a ʻaʻole e hoʻopilikia ʻia ka mamao loaʻa ke hoʻohana pū ʻia;
Ka wela wela: -40-85 ℃ hiki ke hana maʻamau ma lalo o ka wela ambient paʻakikī;
ʻO ka nui liʻiliʻi (hiki ke hoʻopili ʻia e like me nā pono o ka mea kūʻai aku).

No nā noi maʻamau, hiki ke hoʻohana pololei ʻia ka antenna i nā kikoʻī maʻamau o ka mākeke, penei:
315M antenna
Antenna core anawaena (me ka ili) 1.0mm, (koe ka ili) 0.5mm;
Ka lōʻihi o ka uwea welding 17.5mm, ka lōʻihi o ka uea antenna 9.5mm;

ʻAno hoʻonui kūikawā
Inā makemake ʻia kahi mamao kamaʻilio lōʻihi, ʻaʻole hiki ke hoʻokō ʻia ka antenna ʻano noi maʻamau, a hiki ke hoʻohana ʻia kahi antenna i hoʻonui ʻia e hoʻomaikaʻi i ka mamao loaʻa, penei:
315M antenna
Antenna core anawaena (me ka ili) 1.2mm, (koe ka ili) 0.5mm;
Uea hope welding lōʻihi 20mm;

Antenna wili anawaena (koe ka ili) 6.8mm;
He 13 ka nui o ka wiliwili ana, a he 23.5mm ka loihi o ka wiliwili ana.
