Nhau - Helical Duplexer Yekutaurirana kweVHF/UHF

Mabhendi eVHF/UHF anoramba achiita basa guru mukutaurirana kwevanhuwo zvavo uye kwemaindasitiri.duplexer ine helicalInoshanda nemazvo pakusefa, inogara kwenguva refu uye inodhura zvishoma, zvichiita kuti ive sarudzo yepamusoro yemasisitimu eredhiyo, marepeater uye nharembozha.

Chinhu chikuru cheizviduplexer inotakurika inotendererairi mukugadzirwa kwayo kwechimiro chakatenderera, chakabatana nechimiro chakazara¼ λtekinoroji ye resonance. Dhizaini iyi inobvumira kugadzirisa mukati me Mafrequency e150MHz ne380-450MHz anosiyana asi achisvika pakupatsanurwa kwe85 dB—zvichinyatso bvisa zvinhu zvinokanganisa magetsi uye zvichideredza kurasikirwa kwemagetsi zvakanyanya. Pachitarisiko,duplexer ine helicaline imba yealuminium yakapetwa, inowedzerwa nechassis yesimbi isina chinhu uye zvinhu zvakaputirwa neTeflon. Kunze kwayo kwakafukidzwa nevinyl nhema inodzivirira ngura, zvichiita kuti ishande zvakanaka kunyangwe munzvimbo dzakaoma dzekunze uye dzemaindasitiri.

⭐Zviitiko Zvitatu zveKushandiswa Kwepfungwa

1. Zvidzokororo zveSimba Rakaderera: Inochengetedza Voltage Standing Wave Ratio (VSWR) yakaderera panguva yekushanda kwenguva refu, ichideredza zvakanyanya kurasikirwa kwesimba. Inonyanya kukodzera kuiswa pasina anoitarisira munzvimbo dzine makomo, pasi pevhu, nedzimwe nzvimbo, inobatsira kuwedzera kufukidzwa kwekutaurirana.

2. Maredhiyo asina waya edhijitari uye analog: Inofukidza mabhendi emafrequency eVHF 150 MHz uye UHF 380–450 MHz, zvichiita kuti pave nekubatana kwakanaka nemidziyo mikuru pasina chikonzero chekuwedzera frequency. Inobvisa zvachose crosstalk munzvimbo dzakaoma dzemagetsi, ichibatsira kutaurirana kwehunyanzvi uye kushandiswa kweredhiyo.

3.Nharembozha Yakazara Zvishandiso zveDuplex: Iine chimiro chakasimba, inodzivirira kudedera, uye inochinjika pakupisa, inoita kuti chiratidzo chitumirwe zvakanaka uye zvakafanana. Chinhu chakakodzera kuenderana nemamiriro ezvinhu akadai sekununura vanhu panguva yenjodzi uye mashandiro emumunda.

Zvichienzaniswa nehukuru hwe duplexer yechinyakare, chigadzirwa ichi chinowana chiyero chakakwana pakati pekushanda uye kushanda, nezvakanaka zvikuru mukushandisa simba zvakanaka uye kushandisa mari zvakanaka. Chakakodzera kushandiswa kukuru mumapurojekiti madiki uye kusimudzira michina yehunyanzvi, zvichipa rutsigiro rwakasimba kune kutaurirana kwechizvarwa chinotevera kweVHF/UHF..

Tibatei kuti muwane mutengo! Ichi chigadzirwa chinoshandiswa zvakanyanya mukuchengetedza veruzhinji, kutakura zvinhu nekufambisa, otomatiki mumaindasitiri, uye redhiyo yevasina kudzidza, chinovimbwa zvikuru nemusika.
