Kodi microwave matrix switch ndi chiyani?Chida chonsecho kuyeza ndi kuwongolera kumasinthidwa malinga ndi zosowa

Microwave switch, yomwe imadziwikanso kuti RF switch, imayang'anira kutembenuka kwa kanjira ka siginecha ya microwave.

RF (mawayilesi pafupipafupi) ndi masinthidwe a microwave ndi chipangizo chotumizira ma siginecha apamwamba kwambiri kudzera munjira yotumizira.Ma switch a RF ndi ma microwave amagwiritsidwa ntchito kwambiri pamakina oyesera ma microwave poyendetsa ma sigino pakati pa zida ndi zida zoyesedwa (DUT).Mwa kuphatikiza masinthidwe kukhala masinthidwe osinthira masinthidwe, ma siginecha ochokera ku zida zingapo amatha kupita ku DUT imodzi kapena zingapo.Izi zimalola kuti mayeso angapo achitidwe pansi pa zoikamo zomwezo popanda kulumikizana pafupipafupi komanso kulumikizidwa.Njira yonse yoyesera imatha kukhala yokha, motero kuwongolera kupititsa patsogolo m'malo opanga zinthu zambiri.

Kusintha kwa matrix a Microwave

Zosintha za RF ndi microwave zitha kugawidwa m'magulu awiri ofanana komanso ofunikira:

Kusintha kwa Electromechanical kutengera chiphunzitso chosavuta cha electromagnetic induction.Amadalira kukhudzana ndi makina ngati njira yosinthira

Kusinthana ndi chipangizo chodziwika bwino panjira ya RF.Ndikofunikira nthawi iliyonse kusintha kwanjira kumakhudzidwa.Kusintha kwa RF wamba kumaphatikizapo kusintha kwamagetsi, makina osinthira ndi PIN chubu switch.

Chida chilichonse cholimba-state switch matrix

Microwave switch matrix ndi chipangizo chomwe chimathandiza kuti ma siginecha a RF ayendetsedwe m'njira zomwe mungasankhe.Zimapangidwa ndi masiwichi a RF, zida za RF ndi machitidwe owongolera.Kusintha kwa matrix nthawi zambiri kumagwiritsidwa ntchito mu RF/microwave ATE system, yomwe imafunikira zida zingapo zoyesera ndi zida zovuta zoyesedwa (UUT), zomwe zimatha kuchepetsa nthawi yonse yoyezera komanso nthawi zamamanja.

Kutengera 24-port switch matrix ya muyeso wathunthu wa zida ndi kuwongolera monga chitsanzo, itha kugwiritsidwa ntchito poyezera magawo a S ndi kuyeza kwa gawo la ma module a Antenna IO, zosefera zamagulu angapo, ma couplers, ma attenuators, amplifiers ndi zida zina.Maulendo ake oyesera amatha kuphimba ma frequency a 10MHz mpaka 8.5 GHz, ndipo angagwiritsidwe ntchito kwambiri pamayesero angapo monga mapangidwe ndi chitukuko, kutsimikizira zamtundu, kuyesa gawo lopanga, ndi zina zambiri pazida zamadoko.
