Low PIM Attenuators ndi ma RF ndi ma microwave sign attenuators opangidwa mwapadera kuti achepetse mphamvu ya passive intermodulation (PIM). Mphamvu ya PIM imatanthawuza zigawo zowonjezera zowonjezera zomwe zimapangidwa chifukwa cha zotsatira zopanda malire m'zigawo zopanda pake. Zigawozi zidzasokoneza chizindikiro choyambirira ndikuchepetsa magwiridwe antchito.

Cholinga:

1. Kuchepetsa kwa Signal: Othandizira otsika a PIM amagwiritsidwa ntchito kuchepetsa mphamvu ya RF ndi ma siginecha a microwave kuti ateteze zida zolandirira tcheru ndi milingo yowongolera.
2. Chepetsani Passive Intermodulation (PIM) Zotsatira: Ochepetsera a PIM otsika amachepetsa mphamvu ya PIM pogwiritsa ntchito zipangizo zamakono komanso njira zopangira zowonetsera kuti achepetse zotsatira zopanda malire m'zigawo zopanda pake.
3. Kufananiza Impedance: Low PIM RF attenuator angagwiritsidwe ntchito kuti agwirizane ndi kusokonezeka kwa dongosolo, potero kuchepetsa maonekedwe ndi mafunde oima ndikuwongolera machitidwe.

Ntchito:

1. Cellular Communication Base Station: M'malo olumikizirana ndi ma cellular, ma attenuators otsika a PIM microwave amagwiritsidwa ntchito kuchepetsa mphamvu ya PIM, potero kumapangitsa kumveketsa bwino kwazizindikiro komanso kudalirika kwa ulalo wolumikizana. Izi ndizofunikira makamaka pamanetiweki a 4G ndi 5G.
2. Dongosolo la antenna: Mu dongosolo la antenna, otsika PIM millimeter wave attenuator amagwiritsidwa ntchito kuchepetsa zotsatira za PIM ndikuwongolera magwiridwe antchito ndi chizindikiro cha mlongoti. Izi zimathandiza kupititsa patsogolo kufalikira ndi kusamutsa deta pamakina olumikizirana.
3. Dongosolo la Antenna (DAS): M'machitidwe ogawidwa a antenna, otsika PIM mm wave attenuators amagwiritsidwa ntchito kuchepetsa zotsatira za PIM, potero kumapangitsa kuti machitidwe azikhala odalirika komanso odalirika. Izi ndi zofunika kwambiri kwa m'nyumba ndi kunja opanda zingwe Kuphimba njira.
4. Mayeso a Microwave ndi RF: Mu machitidwe oyesera a microwave ndi RF, otsika PIM RF attenuators amagwiritsidwa ntchito kulamulira molondola mphamvu ya siginecha ndikuchepetsa zotsatira za PIM pakuyezetsa mwatsatanetsatane komanso kuyeza.
5. Wailesi ndi TV: Mu machitidwe a wailesi ndi TV, zochepetsera za PIM zochepa zimagwiritsidwa ntchito kuchepetsa zotsatira za PIM ndikuwongolera khalidwe la chizindikiro ndi kufalitsa. Izi zimathandiza kupereka ma audio ndi makanema omveka bwino.
6. Kuyankhulana kwa Satellite: Mu machitidwe oyankhulana a satana, ochepetsera a PIM otsika amagwiritsidwa ntchito kuchepetsa zotsatira za PIM ndikuwongolera kudalirika ndi khalidwe la chizindikiro cha maulalo olankhulirana. Izi ndizofunika kwambiri pamaulumikizidwe apamwamba a satellite.
Mwachidule, ma attenuators otsika otsika (Low PIM Attenuators) amagwiritsidwa ntchito kwambiri m'magawo ambiri monga mauthenga a m'manja, machitidwe a antenna, makina ogawa antenna, kuyesa kwa microwave ndi RF, wailesi ndi wailesi yakanema, ndi mauthenga a satana. Amawongolera magwiridwe antchito ndi kudalirika kwamakina pochepetsa zotsatira za PIM ndikuwongolera mphamvu zama siginecha.

Qualwaveimapereka kulondola kwakukulu komanso mphamvu zambiri za coaxial Low PIM Attenuators zimaphimba ma frequency osiyanasiyana DC ~ 6GHz. Avereji yogwiritsira ntchito mphamvu ndi mpaka 300 Watts. Ma attenuators amagwiritsidwa ntchito pazinthu zambiri pomwe kuchepetsa mphamvu kumafunikira.
