Wararka

RF iyo Mikrowave Filterswaxaa loo isticmaalaa in lagu sifeeyo calaamadaha aan loo baahnayn ee soo galaya nidaamka. Kordhinta heerarka wireless-ka ee xargaha soo noqnoqda ee jira, filtarrada hadda waxay ciyaaraan door aad u muhiim ah waxaana looga baahan yahay inay yareeyaan faragelinta. Waxaa loo qaabeeyey inay ku shaqeeyaan soo noqnoqoshooyin gaar ah oo u oggolaadaan/dhagaysiiye calaamadaha RF ee soo noqnoqoshada kala duwan. Filters-ka RF waxay leeyihiin laba nooc oo xadhkaha soo noqnoqda ah - baasaaska iyo xadhkaha joogsiga. Calaamadaha ku jira baasaaska baasaydhku waxa ay ku dhex mari karaan feejignaan aad u yar halka calaamadaha ku jira xadhiga joogsiga ay la kulmaan attenuation culus.

ShaandhaysoNooca: Waxaa jira noocyo kala duwan oo kala duwan oo filtarrada RF - Band Pass Filters, Low Pass Filters, Band Stop Filters, High Pass Filters iwm Nooc kastaa wuxuu u shaqeeyaa si ka duwan.

Tignoolajiyada: Iyada oo ku saleysan codsiga loo baahan yahay iyo cabbirka nidaamka wireless-ka waxaa jira noocyo kala duwan oo filtarrada - Filters Notch, SAW Filters, Filters Cavity, Waveguide Filters iwm. Mid kastaa wuxuu leeyahay astaamo kala duwan iyo qaabab kala duwan.

Soo noqnoqoshada Baasaboorka (MHz): Kani waa inta jeer ee inta jeer ee ay calaamaduhu ku dhex mari karaan iyadoo ay yar tahay.

Joogsiga Joogsiga (Mhz): Kani waa inta jeer ee inta jeer ee calaamadaha la dhimo. Markasta oo ay sare u kacdo ayaa ka sii fiican. Tan waxa kale oo loo yaqaan go'doomin.

Gelidda Khasaare (dB): Waa khasaaraha dhaca marka calaamaduhu dhex maraan tirada inta jeer ee baska. Hoos u dhaca luminta gelinta ayaa ka sii fiicnaan doonta waxqabadka filtarka.

Stopband Attenuation (dB): Waa hoos u dhigista ay la kulmaan calaamadaha ku dhex jira xadhiga joogsiga ee shaandhada la bixiyay. Baaxadda attenuation ee soo food saartay calaamaduhu way kala duwanaan kartaa iyadoo loo eegayo inta jeer ee ay yihiin.

Wax kasta oo RF ah ayaa ku taxay filtarrada RF ee soosaarayaasha hormuudka ka ah warshadaha. Dooro nooca shaandhada ka dibna isticmaal aaladaha raadinta parametric sida Soo noqnoqoshada, Khasaaraha Gelida, Nooca Xidhmada iyo Awooda si aad u yarayso filtarrada ku salaysan baahidaada. Soo deji xaashida xogta oo arag qeexida alaabta si aad u hesho shaandhada saxda ah ee codsigaaga.

Waxaan sidoo kale u habeyn karnaa qaybaha rf dadban sida waafaqsan shuruudahaaga. Waxaad geli kartaa bogga habaynta si aad u bixiso qeexitaannada aad u baahan tahay.
