RF High Power BroadBand Test Systems 75 ohms Attenuators
75 ohm attenuator ndi mtundu wa attenuator wotchedwa chifukwa cha kulepheretsa kwake 75 ohms.
Ndi gawo losagwira ntchito lomwe limagwiritsidwa ntchito kuwongolera mphamvu ya siginecha ya dera, A 75 ohm attenuator imalepheretsa kukulitsa ndi kupotoza kwa siginecha, ndikuletsa kulephera komwe kumachitika chifukwa cha kuchuluka kwa ma siginecha.
Makhalidwe ake akuluakulu ndi awa:
1. Kufananiza kwa Impedans: Kusokoneza kwa 75 ohm kumagwirizana ndi kulepheretsa kwa mzere wotumizira ma siginecha a zida zamakanema, kuwulutsa pawailesi yakanema ndi makina a kanema wawayilesi, motero amachepetsa kuwunikira 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 zomwe zilibe kanthu ndipo alibe ziwalo zosuntha, ndizodalirika kwambiri ndipo sizifuna kukonzanso kapena kusintha.
75 ohm attenuators amagwiritsidwa ntchito kwambiri pazotsatira zotsatirazi:
1. M'makanema a kanema wawayilesi ndi makanema apawayilesi a digito, amagwiritsidwa ntchito kuwongolera mphamvu zama siginecha ndikuchepetsa kuwunikira komanso 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 zimasintha mphamvu ya siginecha kuti zigwirizane ndi kachitidwe komwe 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 30dB.Ma attenuators okhala ndi kulondola Kwambiri komanso mphamvu zambiri, mtundu wodalirika, zinthu zambiri zimayenderana ndi ROHS, zimatha kukwaniritsa zosowa zosiyanasiyana za makasitomala.
