Waveguide Variable Attenuators Na-aga n'ihu na-atụgharị na-eji aka
Waveguide mgbanwe Attenuators
Na sekit microwave, ike nke akara na-adịkarị elu. Ọ bụrụ na enweghị ike ịchịkwa oke ike zuru oke, ọ ga-adị mfe ịkpata ọtụtụ nsogbu na sekit, dị ka ịfefe oke ike nnabata nke ihe sekit ma na-ebute mgbanwe dị iche iche. Iji waveguide variable attenuators nwere ike gboo mkpa nke ibelata ike mgbaama ma hụ na a na-arụ ọrụ sekit ngwa ndakwa nri.
Ụkpụrụ na-arụ ọrụ nke attenuator na-agbanwe agbanwe na-adabere na njirimara mgbasa nke ebili mmiri electromagnetic na-efegharị efegharị. Ọ na-enwekarị ntuziaka na-efegharị efegharị, ngwaọrụ dakọtara impedance, na ngọngọ ndị na-eduzi mgbanwe. Mgbe mgbaàmà na-agafe n'okirikiri waveguide, akụkụ nke ike ahụ na-etinye aka na ngọngọ nke onye nduzi, si otú ahụ belata ike mgbaàmà.
Mgbe ngọngọ onye na-eduzi bụ ihe eji arụ ọrụ nke onye ọrụ nwere ike iji aka dozie ya, ọ bụ ihe nrịbawanye steepụ rotary. Ndị attenuators na-agbanwe aka bụ ndị enyemaka dị mkpa na sistemụ nkwukọrịta eletrọnịkị.
