Papatūāpapa Rerekē Mahi-Teitei mō ngā Pūrere Oro RF (LNOSiC)

Whakaahua Matua o te Papa Whakairoiro Rerekē Mahi-Teitei mō ngā Pūrere Oro RF (LNOSiC)

Whakaahuatanga Poto:

He wāhanga nui te waeine RF o mua o ngā pūnaha whakawhitiwhiti waea pūkoro hou, ā, ko ngā tātari RF tētahi o ngā poraka hanga tino nui. Ko te mahi a ngā tātari RF ka whakatau tika i te whai huatanga o te whakamahinga o te whānuitanga, te pono o te tohu, te whakapaunga hiko, me te pono o te pūnaha whānui. I te whakaurunga o ngā roopu auau 5G NR me te whanaketanga tonu ki ngā paerewa ahokore a meake nei, me mahi ngā tātari RF i tengā auau teitei ake, ngā whānui whānui ake, ngā taumata mana teitei ake, me te pumau wera kua pai ake.

I tēnei wā, kei te whakawhirinaki tonu ngā tātari oro RF kounga teitei ki ngā hangarau kawemai, engari he iti noa te whanaketanga ā-rohe o ngā rauemi, ngā hoahoa taputapu, me ngā tukanga hanga. Nō reira, he mea nui rawa te rautaki ki te whakatutuki i ngā otinga tātari RF mahi-teitei, tauine-rahi, me te utu-whai hua.

Papamuri Ahumahi me ngā Wero Hangarau

Ko ngā tātari ngaru oro mata (SAW) me ngā tātari ngaru oro papatipu (BAW) ngā hangarau matua e rua i roto i ngā tono RF pūkoro nā te mea he pai te whiriwhiringa auau, te kounga teitei (Q), me te iti o te ngaronga whakaurunga. I roto i ēnei, he mārama ngā painga o ngā tātari SAW i roto ite utu, te pakari o te tukanga, me te kaha hanga nui, ka waiho hei otinga matua i roto i te umanga tātari RF o te whare.

Heoi, he iti noa ngā herenga o ngā tātari SAW tuku iho ina whakamahia ki ngā pūnaha whakawhitiwhiti kōrero matatau 4G me 5G, tae atu ki:

He iti te auau pokapū, e whakawhāiti ana i te kapinga o te whānuitanga 5G NR waenga-me-teitei
Kāore i te rawaka te tauwehenga Q, e whakawhāiti ana i te whānui o te hononga me te mahi a te pūnaha
Te pikinga pāmahana kua whakapuakina
Te kaha whakahaere mana iti

Ko te wikitoria i ēnei here me te pupuri tonu i ngā painga hanganga me ngā painga tukanga o te hangarau SAW he wero hangarau matua mō ngā taputapu oro RF o te whakatipuranga e whai ake nei.

Te Rapunga Whakaaro Hoahoa me te Huarahi Hangarau

Mai i te tirohanga ā-tinana:

Te auau mahi teitei akee hiahiatia ana ngā momo oro me te tere wāhanga teitei ake i raro i ngā āhuatanga roangaru ōrite
Whānui ake te whānui o te whānuie hiahia ana kia nui ake ngā tauwehenga hononga hikohiko
Te whakahaere mana teitei akee whakawhirinaki ana ki ngā paparanga he pai te kawe wera, te kaha miihini, me te iti o te ngaronga oro

I runga i tēnei māramatanga,tā mātou tīma hangaraukua whakawhanakehia he huarahi whakauru kanorau hou mā te whakakotahi i ngāngā kiriata angiangi piezoelectric lithium niobate (LiNbO₃, LN) karaihe kotahimengā papa tautoko tere-oro teitei, kawe-wera teitei, pērā i te silicon carbide (SiC). Ka kiia tēnei hanganga whakauru koLNOSiC.

Hangarau Matua: Papatūāpapa Kanorau LNOSiC

Ka tukuna e te tūāpapa LNOSiC ngā painga mahi tahi mā te hoahoa tahi rauemi me te hanganga:

Hononga Hiko-Mīhini Teitei

He tino pai ngā āhuatanga piezoelectric o te kiriata angiangi LN kotahi-kiriata, e āhei ai te whakaoho pai i ngā ngaru oro mata (SAW) me ngā ngaru Reme me ngā tauwehenga hononga hiko nui, ā, mā reira ka tautoko i ngā hoahoa tātari RF whānui.

Auautanga Teitei me te Mahi Teitei-Q

Mā te tere oro teitei o te papa tautoko ka taea te whakanui ake i ngā auau mahi me te pehi hoki i te turuturu pūngao oro, ka hua ake he kounga pai ake.

Whakahaerenga Wera Pai Rawa

Ko ngā papa tautoko pēnei i te SiC e whakarato ana i te kawe wera tino pai, e whakarei ake ana i te kaha whakahaere mana me te pumau mahi mo te wa roa i raro i ngā āhuatanga mana RF teitei.

Hototahi Tukanga me te Tauine

He tino hototahi te papa rerekē ki ngā tukanga hanga SAW o nāianei, e āwhina ana i te whakawhiti hangarau maeneene, te hanga tauine, me te whakaputanga utu-whai hua.

Hototahi Pūrere me ngā Painga Taumata-Pūnaha

Ka tautokohia e te paparanga kanorau LNOSiC ngā hoahoanga taputapu oro RF maha i runga i te papa rauemi kotahi, tae atu ki:

Ngā tātari SAW tuku iho
Ngā taputapu SAW kua whakamāmāhia te pāmahana (TC-SAW)
Ngā taputapu SAW mahi-teitei whakarei-whakamarumaru (IHP-SAW)
Ngā pūorooro oro ngaru Reme auau-teitei

Ko te tikanga, ka taea e te wafer LNOSiC kotahi te tautokongā huinga tātari RF maha-roopu e hipoki ana i ngā tono 3G, 4G, me te 5G, e tuku ana i te ponoOtinga papaaho oro RF "Katoa-i-te-Kotahi"Ka whakaitihia e tēnei huarahi te uauatanga o te pūnaha, ā, ka taea ai te whakapai ake i te mahi me te kiato whakauru.

Uara Rautaki me te Pānga Ahumahi

Mā te pupuri i ngā painga utu me ngā painga tukanga o te hangarau SAW me te whakatutuki i tētahi pikinga nui o te mahi, ka whakaratohia e te papa LNOSiC heterogeneous heara whai hua, ka taea te hanga, me te whakawhanuiki ngā taputapu oro RF kounga teitei.

Ehara i te mea ko te whakatinanatanga nui anake o ngā pūnaha whakawhitiwhiti kōrero 4G me te 5G tēnei otinga, engari ka whakatūria hoki he turanga rauemi me te hangarau pakari mō ngā taputapu oro RF auau teitei me te mana teitei o te heke mai. He taahiraa nui tēnei ki te whakakapi ā-whare mō ngā tātari RF kounga teitei me te whakawhirinaki ki a ia anō mō te hangarau mō te wā roa.

Ngā Pātai Auau mō LNOSIC

P1: He aha te rerekētanga o LNOSiC i ngā papa SAW tuku iho?

A:Ko ngā taputapu SAW tuku iho ka hangaia i runga i ngā papa piezoelectric papatipu, e whakawhāiti ana i te auau, te tauwehenga Q, me te whakahaere mana. Ka whakauruhia e te LNOSiC he kiriata angiangi LN kotahi-kiriata ki tētahi papa tere-teitei, kawe-wera-teitei, e āhei ai te mahi auau teitei ake, te whānui ake o te whānui, me te kaha hiko kua tino whakapaitia me te pupuri tonu i te hototahi o ngā tukanga SAW.

P2: He aha te whakataurite o LNOSiC ki ngā hangarau BAW/FBAR?

A:He tino pai ngā tātari BAW i ngā auau tino teitei engari me uaua ngā tukanga hanga, ā, he nui ake ngā utu. Ka tukuna e LNOSiC tētahi otinga tautoko mā te whakawhānui i te hangarau SAW ki ngā roopu auau teitei ake me te utu iti ake, te pakari ake o ngā tukanga, me te ngāwari ake mō te whakaurunga maha-roopu.

P3: He pai te LNOSiC mō ngā tono 5G NR?

A:Āe. Nā te tere oro teitei, te hononga hiko nui, me te whakahaere wera pai o te LNOSiC, he mea tino pai mō ngā tātari 5G NR waenga-me te roopu-teitei, tae atu ki ngā tono e hiahia ana ki te whānui o te whānui me te whakahaere mana teitei.
