FILTARAHA RF CAVITY: MAXAY SAMEEYAAN

Waxay caadi ahaan ka kooban yihiin baloogyo waaweyn oo bir ah oo leh xiriiriyayaal RF yar (2 oo loogu talagalay filtarrada iyo 3 oo loogu talagalay duplexers kuwaas oo isku dara calaamadaha Tx iyo Rx ee hal deked anteeno ah).Sida ka muuqata sawirka hoose, filtarradani waxay ka kooban yihiin boolal badan oo dhinac ama ka badan oo jidhkooda ah.Qaar ka mid ah furayaashan ayaa ah biro toosin, halka kuwa kalena loo isticmaalo in lagu xidho saxanka sare ee shashka.

Si loo yareeyo khasaaraha RF oo loo gaaro Q sare ama xulashada shaandhada loo baahan yahay si loo helo khasaare hoose inta lagu jiro baska shaandhada iyo diidmada fiiqan ee ka baxsan baasaska shaandhada, jidhka aluminiumku had iyo jeer waa lagu dhejiyaa (oo leh lacag, naxaas, ama xitaa dahab, laakiin kaliya codsiyada booska).

Dhammaan shabakadaha wireless-ka ee laga bilaabo 1G ilaa 5G, iyo sidoo kale nidaamka isgaarsiinta rayidka iyo militariga, RF Cavity Filters waxay ahaayeen oo sii wadaan inay noqdaan shaqada warshadaha wireless.Waxay leeyihiin kala duwanaansho soo noqnoqda oo aad u ballaaran, oo u dhexeysa 50 MHz ilaa in ka badan 20 GHz.Mawjadaha dhaadheer ee hooseeya awgeed, way yaraanayaan marka uu soo noqnoqoshada kor u kaco (xawaaraha iftiinku waa mid joogto ah waxaana loo xisaabiyaa sida sheyga soo noqnoqda signalada RF iyo hirarkiisa).

In kasta oo baasaaska codsiyada caanka ah ay u dhexeeyaan 1% iyo 10% ee inta jeer ee hawlgalka, RF Cavity Filters waxay bixiyaan codsiyo badan oo la taaban karo maadaama baasbadhkoodu uu ka duwanaan karo wax ka yar 0.5% ilaa 20% inta jeer ee hawlgalka. .Si loo helo wax qabadka ugu fiican ee deegaanka RF ee dhabta ah, inta badan, hadaysan ahayn dhammaan, nidaamyada wirelessku waxay adeegsadaan shaandhada RF Cavity Filters ee u dhexeeya anteenada iyo Raadiyaha (xaddidan calaamadda gelinta LNA si ay u diido soo noqnoqoshada hoose iyo sare ee ka baxsan waxqabadka nidaamka) .

Maaddaama calaamadaha Tx ay aad uga qaylo badan yihiin calaamadaha qaataha ee 120 ilaa 150 dB, RF Cavity Filters sidoo kale waxaa lagu shaqeeyaa calaamada Tx si loo hubiyo in sanqadha iyo qiiqa PA ay xaddidan yihiin oo aysan saameyn ku yeelan naftooda ama nooc kasta oo nidaam wireless ah.
