Momwe Coaxial Fixed Dummy Loads imagwirira ntchito mu Microwave Integrated Circuits

Ma microwave integrated circuits (MICs) asintha kwambiri njira yolumikizirana opanda zingwe ndipo akhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku. Ma circuits amenewa amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana monga kulumikizana kwa satellite, radar systems, ndi mafoni am'manja. Gawo lofunika kwambiri lomwe limagwira ntchito yofunika kwambiri pakugwira ntchito kwa ma circuits awa ndi coaxial dummy load.

Katundu wopangidwa ndi coaxial dummy ndi chipangizo chomwe chimathetsa chingwe chamagetsi kapena chotumizira ndi impedance yolamulidwa. Chimagwiritsidwa ntchito makamaka kuti chigwirizane ndi impedance ya chingwe ndi impedance yodziwika bwino ya chingwe chotumizira. Mu ma microwave integrated circuits, katundu wopangidwa ndi coaxial dummy amatsimikizira kusamutsa mphamvu koyenera, kuchepetsa kuwunikira kwa chizindikiro, ndikuwonjezera magwiridwe antchito a circuit.

Katundu wa coaxial umakhala ndi kondakitala wapakati, zinthu zotetezera kutentha ndi kondakitala wakunja. Kondakitala wapakati ndiye amanyamula chizindikirocho, pomwe kondakitala wakunja amapereka chitetezo ku zosokoneza zakunja. Zinthu zotetezera kutentha zimalekanitsa kondakitala ziwirizi ndikusunga mawonekedwe a impedance a dera.

Chimodzi mwa ubwino waukulu wogwiritsa ntchito zinthu zolemera za coaxial mu ma microwave integrated circuits ndi kuthekera kwawo kuthana ndi ma signal a high frequency. Zinthu zolemera za coaxial dummy load zimapangidwa kuti zisunge impedance yokhazikika pama microwave frequency, kuonetsetsa kuti microwave ikugwira ntchito bwino.

Kuphatikiza apo, katundu wopangidwa ndi coaxial dummy amapereka kusiyanitsa bwino pakati pa ma circuits. Izi ndizofunikira kwambiri m'ma microwave integrated circuits, komwe ma circuits angapo amadzazidwa kwambiri pa chip chimodzi. Kuyika kwa coaxial dummy kumathandiza kuchepetsa kulankhulana kosafunikira komanso kusokonezana pakati pa ma circuits awa, motero kumawongolera magwiridwe antchito onse a circuits.

Ma Coaxial dummy load amapezeka m'njira zosiyanasiyana, kuphatikizapo open circuit, short circuit, ndi ma terminations ofanana. Ma terminations osiyanasiyanawa amalola mainjiniya kusankha coaxial load yoyenera kutengera zofunikira za circuit yomwe akupanga.

Kuyika zinthu zotchedwa coaxial dummy kumagwira ntchito yofunika kwambiri pakugwira ntchito kwa ma microwave integrated circuits. Zimaonetsetsa kuti ma impedance akugwirizana bwino, zimachepetsa kuwunikira kwa ma signal, komanso zimapereka padera pakati pa ma circuits. Chifukwa cha kuthekera kwawo kuthana ndi ma signal amphamvu kwambiri, zinthu zotchedwa coaxial dummy loads zakhala gawo lofunika kwambiri pakupanga ma microwave integrated circuits amakono.
