Raws li RF engineer tshwj xeeb hauv 5G infrastructure, Kuv tau pom tsis muaj kev suav tsis txheeb vim ib qho zais villain:Kev Nkag Ntsej. 
Thaum loj heev Mimo antennas tawg siab-zaus cov paib muaj zog (PAS)Coaxial Circulators.
Yuav ua li cas circulators nyeg teeb liab reflections
Think of a circulator as a "one-way valve" for RF signals. Using ferrite materials under a magnetic bias, it forces signals to flowtsuaslos ntawm TX → antenna → rx chaw nres nkoj, thaum twg khib nyiab mus rau hauv lub nra tawm {} Qhov tseeb "no yog cov tseem ceeb thaiv koj li 5g pa.
Rau 5g cov kev xav tau heev, kev hloov tshiab zoo liNyiaj Them Nqi(e {. g .}}, dapu dp0535c tswj cov vswr<1.2 from -40°C to +85°C) and LTCC miniaturization(40% me me rau loj mimo arrays) yog kev ua si-hloov pauv.
Lub 7 ua-lossis-tawg cov tsis muaj rau cov kab ncig
Xaiv cov pob zeb tsis raug kev phom sij network .} hauv qab no yog cov ntaub ntawv tseem ceeb nrog cov ntaub ntawv tiag tiag:
| Chaw ua uas tsis tau haus | Zoo tagnrho ntau | Vim li cas nws tseem ceeb | Cov qauv ua qauv piv txwv |
|---|---|---|---|
| Muab cais nyob ib leeg | >22Db (sub -6 ghz) | Cov blocks cuam tshuam cov cim los ntawm pa | Dapu DP0535C: 22DB Kev Rho Tawm @ 3.5GHz |
| Poob ntxig | <0.3dB | Cov teeb liab lub zog | UYY CC8080B: 0.3DB @ 60-200 mhz |
