Waveguide Ti o wa titi Attenuators RF Makirowefu Millimeter Wave mm igbi
Waveguide Ti o wa titi Attenuators jẹ ẹrọ palolo ti a lo ni aaye ti imọ-ẹrọ makirowefu.
O jẹ apẹrẹ lati dinku awọn ifihan agbara makirowefu ti o tan kaakiri ni awọn itọsọna igbi ni ipin ti o wa titi. Fun apẹẹrẹ, nigbati ifihan makirowefu ba kọja nipasẹ attenuator ti o wa titi igbi, ipin kan ti agbara naa yoo gba tabi bibẹẹkọ sọnu, nitorinaa dinku agbara ifihan ifihan.
Waveguide jẹ iru ọna itọnisọna igbi ti a lo fun gbigbe awọn microwaves. Attenuator ti o wa titi ti igbi waveguide da lori ilana igbi ati ṣaṣeyọri iye attenuation ti o wa titi nipasẹ ohun elo pataki tabi apẹrẹ igbekale. Nigbagbogbo o nlo awọn ohun elo atako tabi awọn ẹya eletiriki pataki lati fa agbara makirowefu.
Idi:
1. Attenuation Signal: RF attenuators ti wa ni lilo lati ṣe deede agbara agbara RF ati awọn ifihan agbara makirowefu lati daabobo awọn ohun elo gbigba ifura ati awọn ipele ifihan agbara iṣakoso.
2. Ibamu Agbara: Awọn olutọpa Microwave le ṣee lo lati baamu ipele agbara ti eto naa, nitorina o dinku awọn iṣaro ati awọn igbi ti o duro ati imudarasi iṣẹ eto.
3. Iṣatunṣe Eto: Awọn olutọpa igbi Milimita ni a lo lati ṣe iwọn ati idanwo RF ati awọn ọna ẹrọ makirowefu lati rii daju iṣẹ iduroṣinṣin ti eto ni awọn ipele agbara oriṣiriṣi.
Ohun elo:
1. Eto Radar: Ni awọn ọna ṣiṣe radar, awọn attenuators waveguide ni a lo lati ṣatunṣe ati iṣakoso kikankikan ti awọn ifihan agbara ti a firanṣẹ ati ti gba. Eyi ṣe iranlọwọ ilọsiwaju awọn agbara wiwa ati deede ti awọn eto radar.
2. Ibaraẹnisọrọ Satẹlaiti: Ni awọn ọna ẹrọ ibaraẹnisọrọ satẹlaiti, awọn attenuators ti o wa titi ni a lo lati ṣatunṣe agbara ifihan agbara lati rii daju pe igbẹkẹle ati iduroṣinṣin ti ọna asopọ ibaraẹnisọrọ. Wọn le ṣee lo fun gbigbe ifihan agbara laarin awọn ibudo ilẹ ati awọn satẹlaiti.
3. Ibaraẹnisọrọ Microwave: Ni awọn ọna ẹrọ ibaraẹnisọrọ microwave, awọn attenuators makirowefu ni a lo lati ṣatunṣe ati iṣakoso agbara ifihan agbara lati mu iṣẹ ṣiṣe ati igbẹkẹle awọn ọna asopọ ibaraẹnisọrọ ṣiṣẹ.
4. Idanwo ati Wiwọn: Ni RF ati idanwo makirowefu ati awọn ọna wiwọn, awọn attenuators igbi millimeter ni a lo lati ṣakoso ni deede agbara ifihan agbara fun ọpọlọpọ awọn idanwo ati awọn iṣiro. Eyi ṣe pataki lati rii daju iṣẹ ti ẹrọ ati awọn ọna ṣiṣe rẹ.
5. Redio ati Telifisonu: Ni redio ati awọn eto tẹlifisiọnu, mm attenuators igbi ni a lo lati ṣatunṣe agbara ifihan ati ilọsiwaju didara ifihan ati agbegbe. Eyi ṣe iranlọwọ lati pese ohun afetigbọ ati awọn ifihan agbara fidio.
6. Iwadi Imọ-jinlẹ: Ninu awọn iṣẹ iwadii imọ-jinlẹ, awọn olutọpa waveguide ti o wa titi ni a lo lati ṣakoso ati ṣakoso agbara ifihan agbara RF ati makirowefu ni awọn adanwo. Awọn ẹkọ wọnyi le jẹ pẹlu astronomy, fisiksi, ati awọn aaye miiran.
