GPS wolandila wapamwamba kwambiri TQC-GPS-001

TQC-GPS-001 ili ndi VSWR ya 1.5: 1, kuonetsetsa kuti chizindikiro chitayika pang'ono ndikuchita bwino.Kutsekeka kwake kwa 50 ohm kumawonjezera mtundu wa siginecha, ndikupangitsa kuti ikhale yabwino pamapulogalamu ofunikira omwe amafunikira kutsatira kodalirika kwa GPS.

TQC-GPS-001 imagwiritsa ntchito mlongoti wa dzanja lamanja la circular polarization (RHCP), yomwe imapangitsa kuti ikhale yokhoza kulandira zizindikiro za GPS komanso imapereka mphamvu zotsutsana ndi kusokoneza.Izi zikutanthauza kuti mutha kudalira cholandila GPS ichi kuti mupereke deta yolondola komanso yolondola.

Kuwonjezera apo, TQC-GPS-001 ili ndi LNA / fyuluta yokhala ndi phindu la 28dB (popanda chingwe) ndi chithunzi cha phokoso cha 1.5dB chokha.Izi zimawonetsetsa kuti wolandila GPS amatha kukulitsa ma siginecha ofooka ndikuchepetsa phokoso, kuwongolera mtundu wazizindikiro ndi kudalirika.

Kuphatikiza apo, fyuluta ya TQC-GPS-001's yomangidwamo imapereka chiwopsezo chakunja kwa gulu.Kuchepetsa pang'ono kwa f0 +/-20MHZ frequency band ndi 7dB, kutsika kochepa kwa f0 +/-50MHZ frequency band ndi 20dB, ndipo kutsika kochepa kwa f0 +/-100MHZ frequency band ndi 30dB, komwe kumatha kusefa ma frequency osafunikira ndikuchepetsa , kuti mukwaniritse kulondola kolondola komanso kodalirika kwa GPS.

TQC-GPS-001 imagwira ntchito kuchokera ku 3V mpaka 5V, kupereka njira zosinthira magetsi.Ilinso ndi chojambula chochepa cha DC cha 5mA, chokhala ndi 10mA wokwanira, kuwonetsetsa kugwiritsa ntchito mphamvu moyenera.
