Ua ntej, cia peb saib daim duab qhia dav dav ntawm WiFi RF circuits: (Daim duab qhia WiFi feem ntau muab faib ua cov qauv no, nrog rau thaj tsam xiav ntawm RTL8192FR kev koom ua ke hauv MCU)
Kev ua cov teeb liab sib txawv: Feem ntau, WiFi RF teeb liab tau ua tiav siv cov teeb liab sib txawv ua kom muaj peev xwm tiv thaiv kev cuam tshuam.Nyob rau hauv lwm yam lus, lub transceiver yuav xa cov teeb liab nyob rau hauv txawv daim ntawv, thiab sab nraud Circuit Court yuav tsum tau muab tswv yim rau qhov sib txawv RF teeb liab mus rau lub transceiver.
Muaj ob txoj hauv kev los daws nws ntawm no:
1. Los ntawm kev siv lub balancer, lub teeb liab sib txawv nrog rau theem sib txawv ntawm 180 ° yog merged rau hauv ib qho kawg RF teeb liab tom qab dhau los ntawm lub balancer.
2. Discrete Cheebtsam
Dab tsi yog qhov sib txawv teeb liab tau txais los ntawm transceiver?Lub teeb liab tau txais los ntawm lub transceiver los ntawm lub suab nrov nrov amplifier nyob rau hauv pem hauv ntej-kawg.Zoo li lub hwj chim amplifier, lub suab nrov qis kuj tseem ua tiav ib qho kawg RF signals.Yog li ntawd, peb yuav tsum hloov lub teeb liab tso zis los ntawm lub suab nrov nrov amplifier.Lub teeb liab tau txais thiab cov teeb liab ntawm lub transceiver yog yuav luag inverse txheej txheem ntawm ib leeg, yog li cov qauv Circuit Court kuj zoo ib yam li qhov opposite.
Cov saum toj no yog cov ntsiab lus luv luv ntawm WIFI Design Summary - Barron, uas tuaj yeem siv los ua kev siv rau txhua tus.Peb lub tuam txhab muaj ib pab neeg ua haujlwm muaj zog thiab tuaj yeem muab cov kev pabcuam tshaj lij rau cov neeg siv khoom.Tam sim no, peb lub tuam txhab muaj ntau yam khoom: ntseonu, kev sib txuas lus kho qhov muag module, optical fiber module, sfp optical module, olt khoom, Ethernet hloov thiab lwm yam khoom siv network.Yog tias koj xav tau, koj tuaj yeem kawm paub ntxiv txog lawv.
