Iyo dielectric antenna ine yakanakisa kutsanangurwa ine yepakati frequency ye1575.42MHz ± 3 MHz kuve nechokwadi chekugamuchira chiratidzo chekwakaringana.VSWR ndeye 1.5: 1 uye bandwidth iri ± 5 MHz, ichiva nechokwadi chekubatana kwakagadzikana uye kwakanaka nemasatelliti eGPS.Iyo 50-ohm impedance inowedzera kuwedzera kutapurirana kwechiratidzo.
Iyo antenna yakavakirwa pane 7x7cm pasi ndege uye ine peak kuwana inodarika 3dBic.Iyo inopa yakanakisa yekuvhara yekuvhara, kuve nechokwadi chekuwana kushoma kwe -4dBic pa -90 ° uye + 90 ° angles, inovhara kupfuura 75% yevhoriyamu yemudziyo.Iyo polarization ndeyekurudyi-ruoko denderedzwa polarization (RHCP), iyo inogonesa kugamuchirwa kwechiratidzo kubva kumasetellite kumativi ese.
Iyo LNA/sefa inozadzisa iyo dielectric antenna kuti ienderere mberi nekuvandudza mashandiro.Iine 28dB yekuwana (isina tambo) uye yakaderera 1.5dB ruzha nhamba, inokudza isina simba masaini eGPS uye inoderedza kukanganiswa kweruzha, nekudaro ichiwedzera kujeka kwechiratidzo uye kurongeka.
Iyo LNA/firita zvakare ine zvemhando yepamusoro mafirita kuderedza kukanganiswa kwekunze kwebhendi.Inopa hushoma hwe7dB yekudzikamisa paf0+/-20MHz, hushoma hwe20dB paf0+/-50MHz, uye inokatyamadza 30dB yekudzikama paf0+/-100MHz.Izvi zvinova nechokwadi chechiratidzo cheGPS chakajeka uye chepamusoro, kunyangwe munzvimbo dzakazara vanhu uye dzine ruzha.
Iyo VSWR yeLNA/firita isingasviki 2.0, iyo inovimbisa yakaderera kudzoka kurasikirwa kuti iwedzere kufambisa kwemasaini kutapurirana uye kudzikisira chiratidzo.
