Cavity Combiner Ua Haujlwm los ntawm 758-2170MHz JX-CC4-758M2170M-20S1
Kev piav qhia
Cavity Combiner Ua haujlwm ntawm 758-2170MHz
Hauv kev sib txuas lus hauv xov tooj ntawm tes wireless, lub luag haujlwm tseem ceeb ntawm kev sib xyaw ua ke yog sib txuas cov tswv yim ntau-band teeb liab thiab tso tawm rau tib qhov kev faib tawm sab hauv tsev. Lub mixer siv cov thev naus laus zis hloov kho los ntxiv cov teeb liab los ntawm cov khoom siv sib txawv thiab tso tawm mus rau qhov chaw nres nkoj loj. Nws cais thiab txheeb xyuas cov teeb liab ntawm txhua qhov chaw nkag nkag los ntawm kev cuam tshuam kev puas tsuaj, kom ntseeg tau cov teeb liab cais ntawm txhua qhov chaw nres nkoj.
JX-CC4-758M2170M-20S1 yog ib hom kab noj hniav sib xyaw ua ke tsim & tsim tawm los ntawm Jingxin, uas tshwj xeeb tshaj yog nta qhov siab tshaj qhov poob ntawm 1.0dB, ripple hauv BWtsawg dua 1.5dB, thiab qhov tsawg kawg rov poob ntawm 15dB. Thiab qhov sib txawv bandwidth ntawm lub combiner feem yog 122MHz ntawm qhov zaus ntawm 758MHz thiab 880MHz, 45MHz ntawm zaus ntawm 925MHz thiab 960MHz, 75MHz ntawm zaus ntawm 1805MHz thiab 1880MHz, 60MHz ntawm 2210MHz .
Ua raws li tau cog lus tseg, tag nrho cov RF passive Cheebtsam los ntawm Jingxin muaj 3 xyoo lav.

Kev cai RF Passive Cheebtsam
Tsuas yog 3 kauj ruam los daws koj qhov teeb meem ntawm RF Passive Cheebtsam.
1. Txhais qhov parameter los ntawm koj.
2. Muab cov lus pom zoo los ntawm Jingxin.
3. Tsim cov qauv rau kev sim los ntawm Jingxin.
