Waveguide oniyipada Attenuators
Ni awọn iyika makirowefu, agbara awọn ifihan agbara nigbagbogbo ga pupọ. Ti agbara ti o pọ julọ ko ba le ni iṣakoso ni kikun, yoo ni irọrun fa ọpọlọpọ awọn iṣoro ninu Circuit, gẹgẹ bi iwọn iwọn ifarada agbara ti o pọju ti awọn paati iyika ati nfa ọpọlọpọ awọn iyapa. Lilo awọn attenuators oniyipada waveguide le ṣe imunadoko ibeere fun idinku agbara ifihan ati rii daju iṣẹ deede ti awọn iyika makirowefu.
Ilana iṣiṣẹ ti attenuator oniyipada nigbagbogbo da lori awọn abuda itankale ti awọn igbi itanna ni awọn itọsọna igbi. Ni akọkọ o ni awọn itọsọna igbi, awọn ẹrọ ibaramu impedance, ati awọn bulọọki adaorin oniyipada. Nigbati ifihan kan ba kọja nipasẹ itọsọna igbi, ipin kan ti agbara yoo gba nipasẹ bulọọki adaorin, nitorinaa dinku agbara ifihan
Nigbati bulọọki adaorin jẹ ọna ẹrọ ti o le ṣe atunṣe pẹlu ọwọ nipasẹ olumulo, o jẹ awọn attenuators ti o ni iyipo iyipo. Awọn attenuators oniyipada pẹlu ọwọ jẹ awọn oluranlọwọ ko ṣe pataki ni awọn eto ibaraẹnisọrọ itanna.
Ohun elo:
1. Lati rii daju dọgbadọgba ti awọn ipele ifihan agbara ni pq ifihan agbara, awọn attenuators oniyipada waveguide le ṣee ṣe nipasẹ idinku agbara ifihan.
2. Imugboroosi ibiti o ni agbara ti eto naa tun jẹ aaye ti o lagbara ti attenuator ti o ni ipele ti iyipo, eyi ti o le rii daju pe iṣẹ ṣiṣe ti eto naa.
3. Pese ibamu impedance le yago fun ifihan ifihan ati isonu, aridaju iduroṣinṣin ti gbigbe ifihan agbara.
Attenuator oniyipada waveguide jẹ lilo pupọ ni ibaraẹnisọrọ makirowefu ati idanwo yàrá. O le ṣee lo lati ṣatunṣe agbara ifihan lati pade awọn iwulo oriṣiriṣi. Fun apẹẹrẹ, ninu yàrá-yàrá, igbesẹ iyipo le pese awọn agbara atunṣe rọ nigbati agbara ifihan nilo lati yipada lati ṣe idanwo iṣẹ ṣiṣe ohun elo. Ni ibaraẹnisọrọ makirowefu, awọn attenuators oniyipada nigbagbogbo le ṣee lo lati ṣatunṣe agbara ifihan lati rii daju pe ifihan agbara ko lagbara tabi lagbara pupọ lakoko gbigbe.
Awọn anfani ti awọn attenuators oniyipada jẹ ayedero, irọrun ti lilo, ati atunṣe to rọ. Nipa iṣẹ afọwọṣe, awọn olumulo le ṣakoso ni deede ni deede iye attenuation ifihan bi o ṣe nilo. Bibẹẹkọ, ni akawe si awọn attenuators waveguide laifọwọyi, iwọn tolesese ti awọn attenuators waveguide afọwọṣe le jẹ dín, ati ilana atunṣe nilo iye kan ti akoko ati deede.
Qualwaven pese VSWR kekere ati fifẹ attenuation giga lati 0.96 si 500GHz. Iwọn attenuation jẹ 0 ~ 40dB.
