High Power Waveguide Terminations
High Power Waveguide Terminations
Kuyimitsa ma waveguide amphamvu kwambiri ndi chinthu chosagwira ntchito chomwe chimagwiritsidwa ntchito kuyamwa ma siginecha amphamvu kwambiri a microwave, nthawi zambiri pamagetsi opitilira 1 kilowatt. Ndiofanana ndi kutha kwa ma waveguide apakati komanso kutsika kwamphamvu kwa waveguide, ndipo amagwiritsidwa ntchito kuteteza magwiridwe antchito azinthu zina zamakina a microwave, kupewa kuwonetsa ma siginecha, ndikuwongolera kufananiza ndi kukhazikika kwadongosolo.
Pansi pazigawo zogwira ntchito kwambiri, kutha kwamphamvu kwamphamvu kwambiri sikungathenso kukwaniritsa zofunikira za dongosololi, chifukwa chake kutha kwamphamvu kwamphamvu kwambiri kumayambitsidwa kuti athe kupirira mphamvu zambiri kuposa 60W. Izi ndichifukwa choti mafunde amphamvu kwambiri amapangidwa ndi ma waveguide, zida zoyamwa kutentha kwambiri, ndi masinki otentha. Kutentha komwe kumapangidwa mumayendedwe apamwamba kwambiri komanso amphamvu kwambiri a microwave kumatha kusamutsidwa kupita kumlengalenga kudzera pakutha kwa ma waveguide, motero kumasunga magwiridwe antchito bwino komanso kukwaniritsa mawonekedwe otsika komanso mawonekedwe amagetsi okhazikika.
Makhalidwe ake ndi awa:
1. Mphamvu yayikulu yonyamula mphamvu: Kutha kwa ma waveguide amphamvu kumatha kupirira mafunde amphamvu kwambiri a microwave ndi ma millimeter, nthawi zambiri amafikira kusiyanasiyana kwamphamvu kwa ma watts masauzande angapo mpaka makumi a kilowatts.
2. Kutaya kwachiwonetsero chochepa: Mapangidwe a kutha kwa ma waveguide apamwamba kwambiri ndi omveka, omwe amatha kuchepetsa bwino kutayika kwa zizindikiro ndikuwongolera kulondola kwa kuyesa.
3. Kutentha kwakukulu kwa kutentha: Chifukwa cha kufunikira kolimbana ndi kutentha kwa zizindikiro zamphamvu kwambiri, kutha kwa ma waveguide amphamvu nthawi zambiri kumapangidwa ndi zipangizo zapadera ndi zomangamanga kuti zikhale ndi kutentha kwapamwamba kwambiri.
4. Mawonekedwe a Broadband: Kutha kwa ma waveguide amphamvu kumatha kugwira ntchito mosiyanasiyana, koyenera kuyesa ma microwave amphamvu kwambiri ndi ma millimeter ma wave wave pamayendedwe osiyanasiyana.
M'machitidwe ogwiritsira ntchito, kuimitsidwa kwamphamvu kwamphamvu kwa ma waveguide kumagwiritsidwa ntchito poyesa makina a ma microwave a labotale, kuyesa mphamvu ya radiation ya antenna ndi mawonekedwe a radiation, kuwongolera ma siginecha amphamvu kwambiri mu radar ndi machitidwe olumikizirana, kutentha kwa ma microwave ndi kutulutsa kwa plasma, ndi zina. Ndioyenera kuthandizira pakuyesa kwamagetsi apamwamba kwambiri, kukonza, ndi kukonza.
Qualwaveperekani zoletsa za burodibandi ndi ma waveguide amphamvu kwambiri, zomwe zimaphimba ma frequency osiyanasiyana a 2.17 ~ 59.6GHz. Avereji yamphamvu yonyamula mpaka 2500 Watts. Kuletsa kumagwiritsidwa ntchito kwambiri m'mapulogalamu ambiri.
