Yuav ua li cas Coaxial Fixed Dummy Loads ua haujlwm hauv Microwave Integrated Circuits

Cov Microwave integrated circuits (MICs) tau hloov pauv txoj kev sib txuas lus wireless thiab tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub. Cov circuits no tau siv dav hauv ntau yam kev siv xws li kev sib txuas lus satellite, radar systems, thiab xov tooj ntawm tes. Ib qho tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov circuits no yog coaxial dummy load.

Ib qho coaxial dummy load yog ib lub cuab yeej uas xaus ib lub voj voog lossis kab xa xov nrog ib qho kev tswj hwm impedance. Nws feem ntau yog siv los phim qhov impedance ntawm ib lub voj voog rau qhov impedance ntawm ib txoj kab xa xov. Hauv microwave integrated circuits, coaxial dummy loads ua kom muaj kev hloov pauv fais fab kom raug, txo qis kev cuam tshuam ntawm cov teeb liab, thiab ua kom lub voj voog ua haujlwm tau zoo tshaj plaws.

Lub nra hnyav coaxial muaj ib lub xov hlau nruab nrab, cov khoom siv rwb thaiv tsev thiab ib lub xov hlau sab nraud. Lub xov hlau nruab nrab nqa lub teeb liab, thaum lub xov hlau sab nraud muab kev tiv thaiv los ntawm kev cuam tshuam sab nraud. Cov khoom siv rwb thaiv tsev cais ob lub xov hlau thiab tswj cov yam ntxwv impedance ntawm lub voj voog.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv coaxial dummy loads hauv microwave integrated circuits yog lawv lub peev xwm los tswj cov teeb liab zaus siab. Coaxial dummy load yog tsim los tswj kom muaj impedance ruaj khov ntawm microwave frequencies, kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws ntawm lub circuit.

Tsis tas li ntawd xwb, coaxial dummy loads muab kev sib cais zoo heev ntawm cov circuits. Qhov no tseem ceeb heev rau hauv microwave integrated circuits, qhov twg ntau lub circuits tau ntim rau ntawm ib lub chip. Coaxial dummy loading pab txo qhov tsis xav tau crosstalk thiab kev cuam tshuam ntawm cov circuits no, yog li txhim kho kev ua haujlwm ntawm tag nrho cov circuit.

Cov khoom siv coaxial dummy muaj nyob rau hauv ntau yam kev teeb tsa, suav nrog qhib circuit, luv circuit, thiab phim terminations. Cov terminations sib txawv no tso cai rau cov engineers xaiv cov coaxial load tsim nyog raws li cov kev xav tau tshwj xeeb ntawm lub circuit uas lawv tab tom tsim.

Coaxial dummy loading ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm microwave integrated circuits. Lawv ua kom muaj kev sib phim impedance zoo, txo cov teeb liab reflections, thiab muab kev sib cais ntawm cov circuits. Nrog lawv lub peev xwm los tswj cov teeb liab zaus siab, coaxial dummy loads tau dhau los ua ib qho tseem ceeb hauv cov qauv microwave integrated circuit niaj hnub.
