Kuyimitsa kwa PIM kutsika ndi zinthu zomwe zimagwiritsidwa ntchito mu RF ndi makina a microwave omwe amapangidwa kuti achepetse mphamvu ya passive intermodulation (PIM). PIM ndikusokonekera kwa ma siginecha komwe kumachitika chifukwa cha magawo osagwirizana kapena osalumikizana bwino, zomwe zingakhudze kwambiri magwiridwe antchito a njira zoyankhulirana.

Cholinga:

1. Kuyimitsa Chizindikiro: Kuthamanga kwa mawailesi kumagwiritsidwa ntchito kuthetsa mizere yotumizira ma RF ndi ma microwave kuti ateteze kuwonetsetsa kwa ma siginecha ndi kuyimirira kwa mafunde, potero kuwonetsetsa kukhazikika kwadongosolo ndi magwiridwe antchito.
2. Kuponderezedwa kwa PIM: Kuyimitsa kwa RF kumapangidwira kuti achepetse zotsatira za intermodulation, kuonetsetsa kuti ma PIM mu dongosolo amakhala ochepa, motero amawongolera chiyero ndi khalidwe la chizindikiro.
3. Kuwongolera Kwadongosolo: Malo ozungulira ma millimeter amagwiritsidwa ntchito poyesa makina ndi kuyesa kuti atsimikizire kulondola ndi kubwereza kwa zotsatira za kuyeza.

Mawonekedwe:

1. Kutsika kwa PIM kumagwiritsidwa ntchito makamaka poyesa ndi kuyeza kwa RF, kachitidwe kayezedwe ka intermodulation, kuyeza kwa amplifiers kapena ma transmitters amphamvu kwambiri, komanso ngati chipangizo choyezera maukonde osanthula. pa

2. Poyesa ndi kuyeza kwa RF, kuchotsedwa kwa PIM kwa Low PIM kumatsimikizira kulondola kwa mayeso, ndipo mwa kuyamwa ma diaphragms amphamvu, kumapereka chitsimikizo cha kuyeza molondola index ya intermodulation ya zigawo za passive.

3. Mu njira yoyezera ya intermodulation, kuchotsedwa kwa Low PIM kumalumikizidwa ndi doko limodzi la chipangizocho poyesedwa kuti zitsimikizire kupita patsogolo kwa mayeso, apo ayi kuyesako sikungachitike.
Pakuyezera kwa amplifiers kapena ma transmitters amphamvu kwambiri, zoletsa za Low PIM zimagwiritsidwa ntchito m'malo mwa tinyanga ndi kuyamwa mphamvu zonse zonyamula kuti zitsimikizire kulondola kwake.
Monga chida choyezera ma analyzer a netiweki, kutsika kwa intermodulation kumatha kutsimikizira kulondola kwa ma calibration.
Mwachidule, kuchotsedwa kwa Low PIM kumagwiritsidwa ntchito kwambiri m'magawo a RF ndi ma microwave, ndipo ndikofunikira pakuwonetsetsa kuyezetsa ndi kuyeza.

Qualwaveimapereka kutsika kwa PIM kwa ma frequency kuchokera ku DC kupita ku 0.35GHz, ndipo mphamvu imafika ku 200W. Kuchotsa kwathu kwa Low PIM kumagwiritsidwa ntchito kwambiri m'malo ambiri
