Amplifier ya bluetooth ndi mtundu waukadaulo wopanda zingwe wopatsira opanda zingwe. Panthawiyo, ukadaulo wopanda zingwe wakhalapo kwanthawi yayitali, ndipo ena mwa iwo adalowa msinkhu wokhwima. Mwachitsanzo, teknoloji ya infrared imatha kupezeka pazinthu zamagetsi zamagetsi zosiyanasiyana monga zida zapanyumba, makompyuta, mafoni, ndi ma PDA. Phindu lalikulu kwambiri laukadaulo wa infrared ndi mtengo wake wotsika. Koma zofooka zake ndizofanso: kuthamanga pang'ono, kutalikirana pang'ono, chitetezo chochepa, kusalimbana ndi zosokoneza, matekinoloje amphamvu kwambiri opanda zingwe ayenera kubadwa nthawi ndi nthawi kuti akwaniritse zofuna za anthu zaufulu, monga ukadaulo wa bluetooth amplifier.

Kuchokera pakukula kwakale kwa bluetooth amplifier

Pali mpikisano wowopsa pamsika wamagetsi wamagetsi wamagetsi, chifukwa chip ndichofunika chonyamulira pakusintha kwa ukadaulo watsopano wa IT kukhala zinthu. Kaya zinthu zamagetsi zamagetsi zamagetsi zitha kulowererapo zimadalira luso laukadaulo la chip lomwe lingapitirirebe. Poyang'anizana ndi msika womwe ukukula kwambiri, opanga ma semiconductor ambiri apadziko lonse lapansi akuyesetsa mwakhama kupanga tchipisi tating'onoting'ono ta bulutufi kuti tipeze malo okwera kwambiri pamsika. Opanga odziwika bwino am'manja a Nokia ndi Nokia apanga njira ziwiri zamagetsi zomwe zikugwirizana ndi ukadaulo wapano. Ma foni am'manja am'manja a Bluetooth am'manja am'manja ndi mafoni am'manja amtundu wa bluetooth apanga tchipisi tawo tomwe amathandizira. Pambuyo pake, a Philips Semiconductors nthawi ina adakhala pachilumba chokwera chifukwa chogwiritsa ntchito bwino VLS1 Technology ku 1999. Motorola, Toshiba, Intel, ndi IBM nawonso akhala akuchita chitukuko cha chip kapena kugula matekinoloje ofanana ndi ziphaso, koma palibe njira yochitira izi .

Mu 2002, Cambridge Silicon Radio (CSR) ku United Kingdom idakhazikitsa njira yeniyeni ya CMOS single-chip solution (high-frequency component ten baseband controller) yotchedwa BlueCore (bluetooth amplifier core), ndipo idaphatikiza bwino mtundu wotsatira wake BlueCore 2-Mtengo wa Chip chakunja chidatsika mpaka ochepera US $ 5. Pamapeto pake, chojambulira cha bulutufi chinayamba. Kampaniyo yama tchipisi tomwe timatulutsira ma bluetooth mu 2002 inali pafupifupi 18% pamsika wonse. Mwa zida zamakono za ogwiritsa ntchito kumapeto zomwe zimagwirizana ndi bulutufi ya bluetooth 1.1 standard, 59% ili ndi zinthu za CSR. CSR imakhalanso ndi mpikisano, Texas Instruments. Texas Instruments idakhazikitsanso kachipangizo kamodzi ka Bluetooth mu 2002, kamene kamayang'aniridwa ndi kompyuta pafupifupi 25mW, yomwe imapulumutsa kwambiri mphamvu. Chida ichi chimatchedwa BRF6100. Mtengo wogula zambiri ndi 3 mpaka 4 dollars yokha yaku US. Texas Instruments ikukhalanso ndi chip chomwe chimaphatikiza zokulirapo za bluetooth ndi IEEE802.11b. Akuyerekeza kuti kuyambitsa mankhwalawa kumathandizanso kuchepetsa mtengo wama tchipisi cha bulutufi. Kukula kwa ukadaulo wa WUSB kudutsadi mu njira yovuta yomweyo, ndipo mtengowo udzakhala vuto la chitukuko kwa WUSB.

Amplifier ya Bluetooth imathandizira ntchito zochulukirapo

Mafotokozedwe amtundu wa Bluetooth amplifier chip adutsa magawo atatu amakulidwe: 1.0, 1.1 ndi mtundu waposachedwa wa 1.2. Kutumiza kwa data ndikutulutsa mawu ndi zinthu ziwiri zofunika kwambiri pakukweza kwa bluetooth, kuphatikiza doko loyenda lamphamvu la bulutufi, kutumiza mafayilo, kulumikizana kwapaintaneti, chipata cha mawu, fakisi, chomverera m'mutu, kulumikizana kwazidziwitso zaumwini, netiweki yamagetsi yamagetsi, zida za ergonomic, ndi zina zambiri Ntchito ziwirizi zikukulitsidwa. Tiyenera kudziwa kuti zida zambiri zamagetsi zamagetsi zimatha kungopereka zina mwa izi. CSR's BlueCore 3bluetooth amplifier chip imagwiritsa ntchito mtundu waposachedwa wa 1.2, ndipo zogulitsa zake sizinayambikebe pamlingo waukulu. BlueCore 3 ili ndi "kulumikizana mwachangu" komwe kumafupikitsa nthawi yozindikiritsa pakati pa zida zamagetsi zamagetsi kukhala ochepera 1 sekondi, ndipo imatha kudumpha pafupipafupi polumikizana kuti ipewe kusokonekera kwa IEEE802.11b.

Palinso ntchito zina zomwe zimapangitsa kuti phokoso likhale labwino komanso kulumikiza zida zamagetsi zamagetsi. Chosangalatsa ndichakuti zida za chip zochokera pa mtundu 1.1 siziyenera kusinthidwa, ingotsitsimutsani firmware (firmware, yofanana ndi ma boardboard a BIOS) kuti muwonjezere ntchito zomwe zili pamwambapa. Kuphatikiza apo, mphamvu yonse yayikulu ndi 18% kutsika kuposa BlueCore 2-Kunja. Malinga ndi zomwe zafotokozedwazo, ukadaulo wa WUSB uli ndi maukadaulo ambiri kuposa ukadaulo wamagetsi wa bulutufi, koma kupititsa patsogolo ntchito ndizovuta zenizeni zaukadaulo wa WUSB.
