He aha nā ʻāpana i hoʻokomo ʻia i loko o kahi Radio Frequency Front-end

I loko o nā ʻōnaehana kamaʻilio kelepona, ʻehā mau mea maʻamau: ka antenna, radio frequency (RF) front-end, RF transceiver, a me ka baseband signal processor.

Me ka hiki ʻana mai o ka manawa 5G, ua piʻi wikiwiki ka koi a me ka waiwai no nā antenna a me RF mua. ʻO ka RF front-end ka mea nui e hoʻololi i nā hōʻailona kikohoʻe i nā hōʻailona RF uila, a ʻo ia hoʻi ke kumu nui o nā ʻōnaehana kamaʻilio uila.

Ma ka hana, hiki ke hoʻokaʻawale ʻia ka RF mua-hope i ka ʻaoʻao transmit (Tx) a loaʻa i ka ʻaoʻao (Rx).

● Kānana: Koho i nā alapine kikoʻī a kānana i nā hōʻailona hoʻopilikia

● Duplexer/Multiplexer: Hoʻokaʻawale i nā hōʻailona i hoʻouna ʻia/loaʻa

● Mana Hoʻonui (PA): Hoʻonui i nā hōʻailona RF no ka lawe ʻana

● Haʻahaʻa Noise Amplifier (LNA): Hoʻonui i nā hōʻailona i loaʻa me ka hōʻemi ʻana i ka hoʻokomo ʻana i ka walaʻau

● Hoʻololi RF: Hoʻopaʻa i ke kaapuni i ka hoʻololi ʻana i ka hōʻailona

● Tuner: Hoʻohālikelike impedance no ka antenna

● Nā mea ʻē aʻe RF mua-hope

Hoʻohana ʻia kahi Envelope Tracker (ET) no ka hoʻomaikaʻi ʻana i ka pono o ka mana amplifier no nā hōʻailona me ka kiʻekiʻe kiʻekiʻe-a-average mana ratio ma o ka hiki ʻana i nā mana adaptive power amplified outputs.

Hoʻohālikelike ʻia me nā ʻenehana hoʻopaʻa mana maʻamau, ʻae ʻia ka nānā ʻana i ka envelopp i ka mana o ka mana amplifier e hahai i ka envelop o ka hōʻailona hoʻokomo, e hoʻomaikaʻi ana i ka mana o ka mana amplifier RF.

Ua loaʻa i kahi RF Receiver nā hōʻailona RF ma o ka antenna ma o nā ʻāpana e like me nā kānana, LNAs, a me nā analog-to-digital converters (ADCs) e hoʻohaʻahaʻa a hoʻohaʻahaʻa i ka hōʻailona, ​​​​e hoʻokumu i kahi hōʻailona baseband ma ke ʻano he puka.

ʻO Concept Microwave kahi mea hana loea o nā ʻāpana 5G RF ma Kina, me ka kānana haʻahaʻa RF, kānana kiʻekiʻe, kānana bandpass, kānana notch/band stop filter, duplexer, Power divider and directional coupler. Hiki ke hoʻopilikino ʻia lākou a pau e like me kāu requrements.
