RF Front-end Mafirita
1. Low-pass filter: Inoshandiswa pakupinza kweUAV receiver, ine cut-off frequency inenge 1.5 times of the maximum operation frequency, kuvhara high-frequency ruzha uye overload / intermodulation.
2. High-pass sefa: Inoshandiswa pakubuda kweUAV transmitter, ine cut-off frequency yakaderera zvishoma pane yakaderera oparesheni frequency, kudzvanyirira yakaderera-frequency spurious emission interference.
3. Bandpass sefa: Nepakati frequency iri iyo UAV bhendi yekushanda uye bandwidth inofukidza yese bandwidth yekushanda, kusarudza inodiwa chiratidzo bhendi.
Intermediate Frequency Filters
4. Wide bandpass sefa: Nepakati frequency iri IF uye bandwidth inovhara chiratidzo bandwidth, kusarudza iyo IF chiratidzo mushure mekutendeuka kwakawanda.
Narrow bandpass sefa: Ye IF chiratidzo chekuenzanisa uye kudzvinyirira ruzha.
5. Harmonic Filters
Low-pass sefa: Pane transmitter inobuda kudzvanya harmonic emissions pamusoro pekushanda frequency.
Notch sefa: Kusarudza uye zvakanyanya kudzikisira inozivikanwa harmonic frequencies yeanotumira.
6. Sefa Mabhangi: Kubatanidza mafirita akawanda kuti uwane zvirinani kusarudza uye kudzvanywa kweasingadiwe frequency mabhendi uye emissions yenhema.
Izvo zviri pamusoro ndezvimwe zvakajairwa zvemafirita muRF kumberi-kumagumo uye IF kugadzirisa kweUAV kutaurirana, kuvandudza mhando yechiratidzo uye kusarudza.Kune zvakare mafirita echikamu, mafirita anorongwa anoshandiswa muBeamforming network.
Concept Microwave mutengesi wepasirese weakagadziridzwa mafirita, anosanganisira yakaderera sefa, highpass sefa, notch/bhendi yekumisa sefa, bandpass sefa uye kusefa mabhangi.Kuti uwane rumwe ruzivo, ndapota shanyira webhusaiti yedu:www.concept-mw.comkana kutibata pa:sales@concept-mw.com .
