TQC-GPS-001 muaj VSWR ntawm 1.5: 1, kom ntseeg tau tias qhov teeb meem tsawg tsawg thiab ua haujlwm zoo.Nws 50 ohm impedance ntxiv txhim kho cov teeb liab zoo, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev txhim khu kev qha GPS nrhiav.
TQC-GPS-001 txais yuav txoj cai-tes ncig polarization (RHCP) kav hlau txais xov, uas txhim kho nws lub peev xwm kom tau txais GPS teeb liab thiab muaj peev xwm tiv thaiv kev cuam tshuam zoo dua.Qhov no txhais tau tias koj tuaj yeem tso siab rau tus txais GPS no los muab cov ntaub ntawv taug qab kom raug thiab raug.
Tsis tas li ntawd, TQC-GPS-001 muaj LNA / lim nrog qhov nce ntawm 28dB (tsis muaj cable) thiab lub suab nrov ntawm tsuas yog 1.5dB.Qhov no ua kom paub tseeb tias GPS receiver tuaj yeem nthuav tawm cov cim tsis muaj zog thiab txo cov suab nrov, txhim kho cov teeb liab zoo thiab kev ntseeg tau.
Tsis tas li ntawd, TQC-GPS-001's built-in lim muab qhov zoo tshaj plaws tawm-ntawm-band attenuation.Qhov tsawg kawg nkaus attenuation ntawm f0 +/-20MHZ zaus band yog 7dB, qhov tsawg kawg nkaus attenuation ntawm f0+/-50MHZ zaus band yog 20dB, thiab qhov tsawg kawg nkaus attenuation ntawm f0+/-100MHZ zaus band yog 30dB, uas yuav zoo lim tawm tsis xav tau frequencies. , thiaj li ua tiav ntau qhov tseeb thiab txhim khu kev qha GPS nrhiav.
TQC-GPS-001 ua haujlwm los ntawm qhov hluav taws xob ntau ntawm 3V txog 5V, muab cov kev xaiv hloov pauv hloov hluav taws xob.Nws kuj tseem muaj qhov tsis tshua muaj DC tam sim no kos ntawm 5mA, nrog qhov siab tshaj plaws ntawm 10mA, kom ntseeg tau tias siv zog siv tau zoo.
