Lub 8-txoj kev faib hluav taws xob yog qhov ua tau zoo RF / microwave passive tivthaiv tshwj xeeb tsim rau ntau lub teeb liab faib. Nws nta zoo heev zog splitting muaj peev xwm, tsis tshua muaj insertion poob, thiab siab kev sib cais, ua rau nws haum rau xav tau kev sib txuas lus thiab kev ntsuam xyuas ib puag ncig. Nws cov yam ntxwv thiab kev siv yog raws li nram no:
Yam ntxwv:
1. High-power tis: evenly splits 1 input signal rau 8 outputs nrog ib tug theoretical insertion poob ntawm -9dB (8-txoj kev sib npaug faib), xyuas kom meej cov teeb liab kis tau tus mob efficiency.
2. Kev poob qis qis: Siv cov khoom siv high-Q dielectric kom txo qis zog poob.
3. Kev sib cais siab: Ua kom muaj txiaj ntsig zoo cuam tshuam cov teeb liab crosstalk ntawm cov chaw nres nkoj tso zis, txhim kho kev ruaj ntseg.
Daim ntawv thov:
1. Wireless kev sib txuas lus systems
5G hauv paus chaw nres tsheb: Tshaj tawm RF teeb liab rau ntau lub kav hlau txais xov, txhawb nqa MIMO thev naus laus zis.
Distributed antenna systems (DAS): nthuav dav cov teeb liab kev pab cuam thiab txhim kho cov neeg siv ntau lub peev xwm.
2. Satellite thiab radar systems
Phased array radar: sib npaug faib cov cim hauv zos oscillator rau ntau lub TR modules kom ntseeg tau tias beam taw tes raug.
Satellite hauv av chaw nres tsheb: Multi-channel receiver teeb liab faib los txhim kho cov ntaub ntawv dhau los.
3. Kev ntsuas thiab ntsuas
Multi-port network analyzers: Synchronously calibrates ntau yam khoom siv nyob rau hauv kev sim (DUTs) los txhim kho kev soj ntsuam efficiency.
Kev kuaj EMC: Ib txhij ua rau muaj ntau lub kav hlau txais xov kom nrawm rau kev ntsuas hluav taws xob tiv thaiv kab mob.
4. Kev tshaj tawm xov xwm thiab tub rog hluav taws xob
Tshaj tawm cov kab ke sib kis: Tshaj tawm cov cim rau ntau lub feeders kom txo tau qhov kev pheej hmoo tsis ua hauj lwm ib leeg.
Kev ntsuas hluav taws xob hluav taws xob (ECM): Ua kom muaj ntau txoj kev sib koom ua ke jamming teeb liab kis tau tus mob.
