Ho na le tlholisano e matla 'marakeng oa "amplifier chip chip" hobane chip ke sesebelisoa sa bohlokoa bakeng sa phetoho ea mahlale a macha a IT hore e be lihlahisoa. Hore na lihlahisoa tsa mahlale a bluetooth amplifier li ka kenya tlhahiso ea bongata kannete ho latela hore na theknoloji ea tlhahiso ea chip e ka tsoela pele. Ha ba tobane le 'maraka o ntseng o eketseha, baetsi ba li-semiconductor ba maemo a lefats'e ba tsetela ka mafolofolo ho hlahiseng li-chip tsa amplifier tsa bluetooth e le hore ba tsebe ho nka libaka tse phahameng tsa mmaraka. Bahlahisi ba tummeng ba mehala ea thekeng Nokia le Nokia ba hlahisitse litharollo tse peli tsa chip tse fihlelang boemo ba hajoale ba mahlale. Li-cassette tsa amplifier tsa bluetooth tsa pele le liselefounu tsa seholisa tsa bluetooth li iketselitse likhapetla tsa seholisa-Bluetooth. Kamora moo, Philips Semiconductors ka nako e 'ngoe ba ile ba hapa bophahamo bo phahameng ba phepelo ea chip ka lebaka la katleho ea eona ea VLS1 Technology ka 1999. Motorola, Toshiba, Intel le IBM le bona ba nkile karolo ho nts'etsopele ea chip kapa ba reka mahlale a tsamaellanang le laesense, empa ha ho na katleho .

Ka 2002, Cambridge Silicon Radio (CSR) e UK e ile ea hlahisa tharollo ea 'nete ea CMOS single-chip (high-frequency component ten baseband controller) e bitsoang BlueCore (bluetooth amplifier core),' me ea atleha ho kopanya mofuta oa mohlahlami oa eona BlueCore 2 -Theko ea chip ea kantle e theohetse tlase ho US $ 5. Qetellong, sehlahisoa sa seholisa-Bluetooth se ile sa qala. Phepelo ea k'hamphani ea li-chip tsa amplifier tsa bluetooth ka 2002 e bile le 18% ea mmaraka o felletseng. Har'a lisebelisoa tsa hajoale tsa basebelisi ba ho qetela tse lumellanang le standard amplifier ea Bluetooth 1.1, 59% e na le lihlahisoa tsa CSR. CSR le eona e na le mohatelli, Texas Instruments. Liletsa tsa Texas le tsona li phatlalalitse seholisa-Bluetooth se le seng ka 2002, se laoloang ke khomphutha e ka bang 25mW, e bolokang matla haholo. Sehlahisoa sena sa chip se bitsoa BRF6100. Theko ea theko e ngata ke lidolara tse 3 ho isa ho tse 4 tsa Amerika. Texas Instruments e boetse e hlahisa chip e kopanyang seholisa bluetooth le IEEE802.11b. Ho hakanngoa hore ho hlahisoa ha sehlahisoa sena ho tla tsoela pele ho fokotsa theko ea li-chip tsa seholisa-bluetooth. Nts'etsopele ea mahlale a WUSB ka sebele e tla feta tseleng e thata e tšoanang, 'me theko e tla fetoha bothata ba nts'etsopele bakeng sa WUSB.

Litlhaloso tsa Bluetooth amplifier chip li se li fetile mekhahlelo e meraro ea nts'etsopele: 1.0, 1.1 le mofuta oa morao-rao 1.2. Phetiso ea data le phetiso ea molumo ke mesebetsi e 'meli ea mantlha ea seholisa sa bluetooth, ho kenyelletsa koung ea serial ea seholisa sa Bluetooth, phetiso ea faele, marang-rang a ho daela, heke ea lentsoe, fekse, semamedi sa hlooho, khokahano ea taolo ea tlhaiso-leseling ea hau, netweke ea seholisa sa bluetooth, lisebelisoa tsa ergonomic, jj Mesebetsi ena e 'meli ea mantlha ea atolosoa. Ke habohlokoa ho hlokomela hore lisebelisoa tse ngata tsa bluetooth amplifier li ka fana feela ka tse ling tsa mesebetsi ena. CSR's BlueCore 3bluetooth amplifier chip e sebelisa mofuta oa morao-rao 1.2, 'me lihlahisoa tsa eona tse tsamaellanang ha li so hlahisoe ka bongata. BlueCore 3 e na le ts'ebetso ea "khokahanyo e potlakileng" e khutsufatsang nako ea ho khetholla lipakeng tsa lisebelisoa tsa seholisa-Bluetooth ho isa tlase ho motsotsoana o le mong, mme e ka tlola makhetlo a mangata nakong ea puisano ho qoba tšitiso ea IEEE802.11b.

Ho boetse ho na le mesebetsi ea ho ntlafatsa boleng ba phetiso ea molumo le ho hokahanya lisebelisoa tse ling tsa seholisa-Bluetooth. Ho thabisang ke hore lisebelisoa tsa chip tse ipapisitseng le mofuta oa 1.1 ha li hloke ho fetoloa, khatholla firmware feela (firmware, e ts'oanang le board ea mama ea BIOS) ho eketsa mesebetsi e kaholimo. Ntle le moo, ts'ebeliso eohle ea motlakase e ka tlase ho 18% ho feta BlueCore 2-External.
