75 ohms attenuator ndi mtundu wa attenuator wotchedwa chifukwa cha kulepheretsa kwake 75 ohms.

Ndi gawo lokhazikika lomwe limagwiritsidwa ntchito kuwongolera mphamvu ya siginecha ya dera, A 75Ω attenuator imalepheretsa kukulitsa ndi kupotoza kwa siginecha, ndikuletsa kulephera komwe kumachitika chifukwa cha kuchuluka kwa ma siginecha.

75Ω zowongolera zokhazikika zazikuluzikulu zikuphatikizapo:

1. Kufananiza kwa Impedans: The 75 Ohms fixed attenuator impedance ikufanana ndi kulepheretsa kwa mzere wotumizira mauthenga a mavidiyo, kuwulutsa pawailesi yakanema ndi makina a wailesi yakanema, motero kuchepetsa kuwonetsetsa ndi kutayika kwa chizindikiro chotumizira.
2. Kusokoneza pang'ono: Wothandizira amatha kuchepetsa mphamvu ya chizindikiro popanda kuyambitsa kusokoneza kwina kapena kusokoneza chizindikiro.
3. Kudalirika kwakukulu: Chifukwa chakuti ma attenuators ali makamaka zigawo zapansi ndipo alibe magawo osuntha, ndi odalirika kwambiri ndipo safuna kukonza kapena kusintha.

75 ohms attenuators amagwiritsidwa ntchito kwambiri pazotsatira zotsatirazi:

1. Mu maukonde a wailesi yakanema ndi ma televizioni a digito, amagwiritsidwa ntchito kuwongolera mphamvu za siginecha ndikuchepetsa kuwunikira ndi kutayika kwa ma siginecha.
2. Panthawi yopanga ndi kufalitsa mavidiyo apamwamba komanso omveka bwino, sungani mphamvu ya chizindikiro ndikusunga khalidwe la kutembenuka.
3. M'mawu owulutsa ndi ma wailesi yakanema, zida zomwe zimasinthira mphamvu yazizindikiro kuti zigwirizane ndi kachitidwe kamene kagawika ndi kukulitsa ma siginecha.
4. Mu tinyanga ta wailesi yakanema, amagwiritsidwa ntchito kulinganiza mphamvu ya chizindikiro pakati pa amplifiers ndi tinyanga.

Qualwaveimapereka ma attenuators osiyanasiyana olondola kwambiri komanso apamwamba kwambiri a coaxial 75 ohms omwe amaphimba ma frequency osiyanasiyana DC ~ 3GHz, amatha kufananizidwa ndi zolumikizira za BNC, F-mtundu, ndi N-mtundu. The attenuation makamaka ranges kuchokera 1 mpaka 40dB. Ma attenuators okhala ndi kulondola Kwambiri komanso mphamvu zambiri, mtundu wodalirika, zinthu zambiri zimayenderana ndi ROHS, zimatha kukwaniritsa zosowa zosiyanasiyana za makasitomala.
