Ko te attenuator 75 ohms he momo attenuator i tapaina nā tōna parenga o te 75 ohms.

He wāhanga kore e whakamahia ana hei whakahaere i te kaha o te tohu o tētahi ara iahiko. Ka ārai te attenuator 75Ω i te whakanui nui me te whakapōturi o te tohu, ā, ka ārai hoki i te rahunga e puta mai ana i te taumaha rawa o te tohu.

Ko ngā āhuatanga matua o ngā whakangāwari pumau 75Ω ko:

1. Te whakataurite i te aukati: Ko te aukati whakaiti pumau 75 Ohms ka rite ki te aukati āhuatanga o te raina tuku tohu o te taputapu ataata, te pāhotanga pouaka whakaata me te pūnaha pouaka whakaata taura, ā, ka whakaitihia te whakaata me te ngaronga o te tohu tuku.
2. He iti te whakapōturitanga: Ka taea e te attenuator te whakaiti i te kaha o te tohu me te kore e whakauru i ētahi atu whakapōturitanga, whakararuraru rānei i te tohu.
3. Te tino pono: Nā te mea he wāhanga korekore te nuinga o ngā attenuators, ā, kāore he wāhanga e neke ana, he tino pono ēnei, ā, kāore e hiahiatia he tiaki, he whakakapinga rānei.

E whakamahia whānuitia ana ngā attenuators 75 ohms i roto i ngā tono e whai ake nei:

1. I roto i ngā whatunga pouaka whakaata taura me ngā whatunga pouaka whakaata mamati, ka whakamahia hei whakahaere i te kaha o te tohu me te whakaiti i te whakaata me te ngaronga o te tohu.
2. I te wā e hanga ana, e tuku ana hoki i ngā ataata taumira teitei me te whakamāramatanga teitei, whakahaeretia te kaha o te tohu, me te pupuri tonu i te kounga tahuritanga.
3. I roto i ngā pūnaha tuku tohu pāho me te pouaka whakaata, he taputapu e whakarerekē ana i te kaha o te tohu kia ōrite ki te tukatuka tohu tohatoha motuhake me te whakawhānui i te whānuitanga o te tohu.
4. I roto i ngā pūihi pouaka whakaata, e whakamahia ana hei whakataurite i te mana tohu i waenga i ngā whakakaha me ngā pūihi.

QualwaveE whakarato ana i ngā momo attenuators coaxial 75 ohms tino tika me te mana teitei e kapi ana i te awhe auau DC ~ 3GHz, ka taea te hono atu ki ngā hononga BNC, momo-F, me te momo-N. Ko te nuinga o te attenuators kei waenga i te 1 ki te 40dB. Ko ngā attenuators he tino tika me te mana teitei, he kounga pono, he maha ngā hua e tutuki ana i ngā whakaritenga ROHS, ka taea te whakatutuki i ngā hiahia rerekē o ngā kiritaki.
