Tsananguro yeChigadzirwa
1. Pfupiso yeChigadzirwa
SA1300CAmplifier yekunze ine mativi maviri ndiyo amplifier itsva yakagadzirwa ine hunyanzvi hwepamusoro. Dhizaini yedunhu yakakura uye yakagadziriswa, maitiro emukati esainzi uye ane musoro uye zvinhu zvemhando yepamusoro, zvinoita kuti pave nekuwedzera kwakagadzikana uye kukanganiswa kwakaderera. Ndiyo sarudzo yakanakisa yekuvaka network yekutumira yeCATV hombe kana yepakati yekutakura madivi maviri.
2. Hunhu hweKushanda
- Danho rekutanga rinotanga nekushandisa module itsva ye "high index imported low noise push-pull amplifier" kana kuti GaAs push-pull module, danho rekubuda rinoshandisa "high index imported power doubl" itsva.ymodule yeamplifier kana module yeGaAs amplifier. Iyo nonlinear index yakanaka uye huwandu hwekubuda hwakagadzikana. Nzira yekudzoka inoshandisa module itsva yeamplifier inopinzwa ine index yepamusoro. Kukanganiswa kwakaderera uye chiyero chechiratidzo kune ruzha chakakwira.
- Zviri nyore kugadzirisa dambudziko nekuda kwe plug-in duplex filter, plug-in fixed (kana adjustable) equalizer uye attenuator, uye ma ports ekuona ari paindaneti ane ruzivo uye anonzwisisa.
- Midziyo iyi inogona kushanda kwenguva refu ichienderera mberi kana mamiriro ekunze asina kunaka. Nekuda kweimba yealuminium isingapindi mvura, simba rekuchinja rakavimbika uye sisitimu yakasimba yekudzivirira mheni.
- Goko rinoshandisa dhizaini yemodular yakavharirwa; kugadzirisa michina, kutsiva, uye kugadzirisa matambudziko zviri nyore.
3. Gwaro reKuraira
Ndapota simbisai: kupatsanurana kwenzira dziri munzira mbiri (uplink) nedziri pasi (downlink).
4. Mazano Akakosha:
- Usati washandisa chigadzirwa, grounding inofanira kunge yakavimbika!
- Kukwanisa kukuru kwechigadzirwa ichi kuita magetsi akawanda i10A.
