ʻO WF105RB kahi mea hoʻololi pololei haʻahaʻa OOK/ASK. Hoʻolālā nui ʻia ke kaapuni no ka hui ISM (Industrial, Scientific and Medical) 315/433MHz, ua hoʻolālā ʻia no ka lawe ʻana i ka ʻikepili haʻahaʻa.
ʻōnaehana no ka helu ʻikepili ma lalo o 40Kb/s ma Manchester.
Hoʻohui ʻo WF105RB i ka hapa nui o nā ʻāpana kaapuni ma ka chip a koi wale i kekahi mau mea waho e hana maʻamau. Aia ka WF105RB me kahi mea hoʻonui haʻahaʻa haʻahaʻa (LNA), kahi hui hoʻololi i lalo, apuʻupuʻu puʻupuʻu puʻupuʻu (PLL) me ka oscillator i hoʻopaʻa ʻia i ka uila uila (VCO) a me ka kānana loop, kahi ASK demodulator, kahi kānana ʻikepili, kahi mea hoʻohālikelike ʻikepili a me kahi mea hoʻoponopono ma-chip.
Hoʻolālā ʻia ka WF105RB no ka mana haʻahaʻa a me ka haʻahaʻa haʻahaʻa uila uila. Loaʻa ia i loko o ka pūʻolo TSSOP-16 a me ka hana ʻana ma luna o ka pae wela lōʻihi (-40 a +85 ° C).

Precations
- Ke nānā nei kēia polokalamu i ka uila static. Pono e hoʻohanaʻia nā alanti-Static i ka wā o ka laweʻana a me ka hoʻohanaʻana.
- E hoʻohana i ka polokalamu e like me nā noi maʻamau i manaʻoʻia.
- ʻO nā hoʻololi e hoʻololiʻia i nā kiko'ī o kēia huahana e hanaʻoleʻia me kaʻole o ka leka hoʻomaopopo.
