ʻO nā hoʻopau PIM haʻahaʻa he ʻāpana passive i hoʻohana ʻia i nā ʻōnaehana RF a me ka microwave i hoʻolālā ʻia e hōʻemi i ka hopena passive intermodulation (PIM). ʻO ka PIM ka hōʻailona distortion i hoʻokumu ʻia e nā ʻāpana laina ʻole a i ʻole nā pilina maikaʻi ʻole, hiki ke hoʻopilikia nui i ka hana o nā ʻōnaehana kamaʻilio.

Ke kumu:

1. Hoʻopau hōʻailona: Hoʻohana ʻia ka haawe lekiō e hoʻopau i nā laina hoʻouna RF a me ka microwave no ka pale ʻana i ka noʻonoʻo ʻana o ka hōʻailona a me ka hoʻokumu ʻana o ka nalu kū, a laila e hōʻoia i ka paʻa o ka ʻōnaehana a me ka hana.
2. PIM Suppression: Hoʻonohonoho pono ʻia nā hoʻopau RF e hōʻemi i nā hopena intermodulation passive, e hōʻoia ana e mālama ʻia nā pae PIM i ka ʻōnaehana i ka liʻiliʻi, no laila e hoʻomaikaʻi ai i ka maʻemaʻe a me ka maikaʻi o ka hōʻailona.
3. Pūnaehana Calibration: Ua hoʻohana ʻia nā pahu hawewe millimeter no ka hoʻoponopono ʻana i ka ʻōnaehana a me ka hoʻāʻo ʻana e hōʻoia i ka pololei a me ka hana hou ʻana o nā hopena ana.

Nā hiʻohiʻona:

1. Hoʻohana nui ʻia ka haʻahaʻa PIM haʻahaʻa no ka hoʻāʻo ʻana a me ke ana ʻana o RF, nā ʻōnaehana ana intermodulation passive, ke ana ʻana o nā mea hoʻonui a i ʻole nā mea hoʻouna, a ma ke ʻano he mea calibration no nā mea nānā pūnaewele. ?

2. Ma ka ho'āʻo a me ke ana RF, ʻo ka hoʻopau PIM haʻahaʻa e hōʻoia i ka pololei o ka hoʻāʻo, a ma ka hoʻokomo ʻana i nā diaphragms mana, hāʻawi ia i kahi hōʻoia no ke ana pono ʻana i ka index intermodulation o nā ʻāpana passive.

3. I loko o kahi ʻōnaehana ana intermodulation passive, hoʻopili ʻia kahi hoʻopau haʻahaʻa PIM i hoʻokahi awa o ka hāmeʻa ma lalo o ka hoʻāʻo e hōʻoia i ka holomua o ka hoʻāʻo, inā ʻaʻole hiki ke hoʻokō ʻia ka hoʻāʻo.
I ke ana ʻana o nā mea hoʻonui mana kiʻekiʻe a i ʻole nā mea hoʻouna, hoʻohana ʻia nā hoʻopau PIM haʻahaʻa e pani i nā antenna a hoʻopaʻa i nā mana lawe āpau e hōʻoia i ka pololei o ke ana.
Ma ke ʻano he mea calibration no nā mea nānā pūnaewele, hiki i ka haʻahaʻa intermodulation haʻahaʻa ke hōʻoia i ka pololei o ka calibration.
I ka hōʻuluʻulu ʻana, hoʻohana nui ʻia ka hoʻopau PIM haʻahaʻa i ka RF a me ka microwave, a he mea koʻikoʻi ia no ka hōʻoia ʻana i ka pololei o ka hoʻāʻo a me ke ana.

Kaʻaleʻaleʻahāʻawi i ka hoʻopau PIM haʻahaʻa ma nā alapine mai DC a 0.35GHz, a ʻo ka mana a hiki i 200W. Hoʻohana nui ʻia kā mākou hoʻopau PIM haʻahaʻa ma nā wahi he nui
