ʻO Qualcomm Technologies, ma kahi o , hoʻolauna i kāna ʻenehana kānana ultraSAW RF no nā polokalamu kelepona 4G/5G. Hoʻomaikaʻi nui ia i ka hana alapine radio ma nā pae a hiki i 2,7 GHz a, e like me ka mea hana, ʻoi aku ka maikaʻi ma mua o nā mea hoʻokūkū ma ke ʻano o nā palena a me nā kumukūʻai.
Hoʻokaʻawale ka lekiō alapine (RF) i nā hōʻailona lekiō ma nā ʻāpana like ʻole i hoʻohana ʻia i nā kelepona paʻalima e loaʻa a hoʻouna i ka ʻike. Ma ka hōʻemi ʻana i ka poho hoʻokomo ʻana ma ka liʻiliʻi he 1 dB, ʻoi aku ka maikaʻi o nā kānana Qualcomm ultraSAW surface acoustic wave (SAW) ma mua o nā kānana acoustic wave kino (BAW) a hiki i 2,7 GHz.
Hōʻike ʻia ʻo Qualcomm ultraSAW i ka hana kānana kiʻekiʻe ma ka pae 600 MHz - 2,7 GHz, a ua ʻike ʻia e kēia mau mea pono:
- ka hoʻokaʻawale maikaʻi loa o nā hōʻailona i loaʻa a hoʻouna ʻia a me ka hoʻopaʻa ʻana i nā crosstalk;
- ke koho alapine kiʻekiʻe;
- ʻoi aku ka maikaʻi a hiki i 5000 - ʻoi aku ka kiʻekiʻe ma mua o nā kānana OAV hoʻokūkū;
- haʻahaʻa loa hoʻokomo poho;
- kiʻekiʻe wela me ka haʻahaʻa haʻahaʻa haʻahaʻa o ke kauoha o x10-6/deg. TO.
Hāʻawi ka ʻenehana i nā mea hana e hoʻomaikaʻi i ka pono o ka ikehu o nā hāmeʻa multi-mode 5G a me 4G ʻoiai e hōʻemi ana i nā kumukūʻai i hoʻohālikelike ʻia i nā hopena hoʻokūkū me nā ʻano ʻenehana like. Ma muli o ka hoʻohana ʻana i ka ʻenehana, e hana autonomously lōʻihi nā smartphones, a e hoʻonui ʻia ka maikaʻi o ke kamaʻilio. E hoʻomaka ka hana ʻana o ka ʻohana Qualcomm ultraSAW o nā huahana discrete a i hoʻohui ʻia i ka hapaha o kēia manawa, a ʻike ʻia nā mea hae mua e pili ana iā ia i ka hapa lua o 2020.
ʻO Qualcomm ultraSAW kahi ʻenehana koʻikoʻi e hoʻomaikaʻi hou i ka hana o ka ʻoihana RFFE portfolio a me nā ʻōnaehana modem Snapdragon 5G Modem-RF. Hoʻohana ʻia ka ʻenehana Qualcomm ultraSAW i nā modules amplifier mana (PAMiD), nā modula hope mua (FEMiD), nā modula diversity (DRx), nā mea unuhi Wi-Fi, nā mea hoʻokele hōʻailona hoʻokele (GNSS extractors), a me RF multiplexers.
