Waa maxay sababta filtarrada RF ay u noqonayaan kuwa muhim ah?
Kobaca degdega ah ee xogta wireless-ka mobaylada iyo shabakadaha 4G LTE ayaa horseeday baahida sii kordheysa ee loo qabo kooxo cusub iyo isu geynta sideyaasha si ay isugu geeyaan xadhkaha si ay u dajiyaan taraafikada wireless-ka. Shabakadda 3G waxa ay isticmaashaa ilaa shan xabbo oo kaliya, shabakadaha LTE-na hadda waxa ay adeegsadaan in ka badan 40 xabo, marka uu 5G yimaado, tirada guutuhu waxa ay sii kordhin doontaa.
Aaladaha ku xidhan waxa ay soo diraan calaamado xadhkaha badan: gacanta, Wi-Fi, Bluetooth, iyo GPS, iyada oo laga fogaanayo faragelinta. Waxa laga yaabaa inaan isla markiiba ka fikirno talefannada casriga ah, baalalka shark ee ku rakiban baabuurta dushooda, saldhigyada gacanta ee gacanta, radarka iyo nidaamyada isgaarsiinta, iyo warshadaha, sayniska, ama codsiyada caafimaadka ee ku xiran Internetka Waxyaabaha (IoT). Halkaa marka ay marayso, filtarka ayaa loo baahan yahay si uu u soo baxo.
Casriga casriga ah ee aan lahayn filter waa leben
Sida anteenooyinka, filtarrada waxay noqonayaan qayb sii kordheysa oo muhiim ah isku dhafka isku xirka. Qalabku wuxuu helayaa noocyo kala duwan oo soo noqnoqonaya, shaandheyntuna waxay u oggolaanaysaa inta jeer ee la rabo in la dhex maro iyada oo la xakameynayo inta jeer ee aan la rabin. Si kale haddii loo dhigo, shaandheyntu waa sida Gandalf ee John Ronald Ryall Tolkien ee "The Lord of the Rings": "Ma gudbi doontid!" "Aaladaha maanta waxaa badanaa lagu qalabeeyaa 30 ilaa 40 filtarrada si looga fogaado faragelinta, xaaladdani waxay noqon doontaa mid aad u adag maadaama jiilka soo socda ee casriga casriga ah uu u baahan yahay filtarro badan.
Kala shaandheynta caqabadaha naqshadeynta
Shaandheeyayaashu waa qalab lagama maarmaan u ah injineerada naqshadaynta RF, laakiin sidoo kale waxay la kulmaan caqabado badan. Bilawga, waxqabadka filtarka ayaa ku kala duwan heerkulka. Shaandhaynta aaladaha kala duwan ayaa maanta u adkeysan kara celceliska heerkulka 60 darajo Celsius (140 darajo Fahrenheit) ama ka sareeya, halka filtarrada gudaha ay u adkeysan karaan celceliska heerkulka 25 darajo Celsius (77 darajo Fahrenheit) iyo xitaa heerkul sare oo loogu talagalay baalasha shark ama filtarrada ku dhex jira saqafka. Heerkulka filtarku mar kasta oo uu sarreeyo, way adkaanaysaa in la sifeeyo inta jeer ee gaar ah, waxayna u badan tahay inay tahay in calaamaduhu "u leexan doono" qaybta ku xigta.
Maareynta qulqulka heerkulka ayaa si gaar ah muhiim u ah sababtoo ah qaar badan oo ka mid ah kooxaha cusub ee la qoondeeyay ayaa aad ugu dhow kooxaha jira. Isla mar ahaantaana, isu geynta side (CA) si xawli ah ayey u koreysaa, iyadoo bixiyeyaasha adeegga gacanta ay isku daraan ilaa shan kanaal sideyaal si loo caddeeyo waxqabadka shabakadda, halkaasoo sifeyn sax ah ay tahay shardi.
Si wax looga qabto arrimaha heerkulka, warshadaha RF waxay horumarinayaan tignoolajiyada shaandheynta-hooseeya iyo faleelka-free. Surface Sonic (SAW) iyo Body Sound Wave (BAW) filtarrada waxay ilaalinayaan xasillooni heer sare ah marka heerkulku isbeddelo, iyagoo buuxinaya shuruudaha waxqabadka baahida ee aaladaha soo baxaya.
Sida kor ku xusan, jiilka soo socda ee casriga ah ee casriga ah ayaa sidoo kale u baahan in lagu qalabeeyo filtarrada badan. Sida dhammaan qaybaha kale ee rf, waxaa jira meel aad u yar oo filtarrada. Injineerada waa in ay awoodaan in ay isku daraan filtarrada badan meelo yar yar si loo helo waxqabad sare.
Duplexers, triplexers, cuadruplexers iyo hexaplexers ayaa si wada jir ah loogu tilmaamaa kuwo badan. Multiplexers-ku waxay isku daraan filtarrada badan hal qalab si ay uga caawiyaan naqshadeeyayaasha inay badbaadiyaan booska, fududeeyaan naqshadeynta, buuxiyaan shuruudaha waxqabadka, ugana fogaadaan faragelinta.
Deegaanka mobilada ee maanta, tirada band-yada looga baahan yahay aaladda ayaa ah mid aad u liidata, markii uu soo baxay casrigii 5G, isbadalkani wuu sii xumaanayaa. Iyadoo taageeridda dhammaan guutooyinka ay sababi karto dhibaatooyinka faragelinta, dhibaatada waxaa lagu xallin karaa shaandho. filtar la'aan, shabakadu si fudud uma shaqeyso.
