Tace Karamar Wucewa:

Kamar yadda sunan ke nunawa, matattara mai ƙarancin wucewa shine tacewa wanda kawai ke ba da damar ƙananan mitoci su wuce tare da rage wasu mitocin sigina a lokaci guda. Lokacin da sigina ta wuce ta hanyar bandeji, ana ƙayyade raguwar mitar ta da abubuwa da yawa, kamar tace topology, shimfidawa da ingancin sassa. Bugu da kari, tace topology shima yana kayyade saurin sauyawar tacewa daga fasfon din don cimma nasarar dakile shi.

Ƙananan matattarar wucewa suna zuwa ta hanyoyi daban-daban. Babban aikace-aikacen tace shine don murkushe jituwa na RF amplifier. Wannan fasalin yana da mahimmanci saboda yana taimakawa hana tsangwama mara amfani daga maɓallan watsawa daban-daban. Da farko, ana amfani da ƙananan matattarar wucewa don aikace-aikacen sauti da kuma tace hayaniya daga kowace kewayen waje. Bayan an tace sigina mai girma, mitar siginar da aka samu tana da ingantaccen inganci.

Tace Mai Girma:

Ya bambanta da ƙananan matatun wucewa, babban tacewar wucewa yana ba da damar sigina mai girma kawai don wucewa. A haƙiƙa, matattara mai ƙarfi da ƙaramin wucewa suna da alaƙa sosai, saboda ana iya amfani da matatun biyu tare don samar da tace band-pass. Zane-zanen babban tacewa kai tsaye kuma yana rage mitar da ke ƙasa da maƙallan kofa.

Gabaɗaya, ana amfani da matattara mai ƙarfi a cikin tsarin sauti, ta inda ake tace duk ƙananan mitoci. Bugu da ƙari, ana amfani da shi don cire ƙananan lasifika da bass a yawancin lokuta; Waɗannan filtattun an gina su musamman a cikin lasifika. Koyaya, idan kowane aikin DIY ya shiga, za'a iya haɗa babban tacewar zaɓi zuwa tsarin cikin sauƙi.

Band Pass Filters:

Fitar band-pass shine da'irar da ke ba da damar sigina daga mitoci daban-daban guda biyu don wucewa da kuma rage sigina waɗanda ba su cikin kewayon da aka yarda da su. Yawancin matatar band-pass sun dogara da kowane tushen wutar lantarki na waje kuma suna amfani da kayan aiki masu aiki, wato hadedde da'irori da transistor. Ana kiran wannan nau'in tacewa mai aiki band-pass filter. A gefe guda, wasu matatun band-pass ba sa amfani da wutar lantarki ta waje kuma suna dogara kacokan akan abubuwan da ba a iya amfani da su ba, wato inductor da capacitors. Ana kiran waɗannan masu tacewa masu wucewa ta hanyar wucewa.

Ana yawan amfani da matatar bandpass a cikin masu karɓar mara waya da masu watsawa. Babban aikinsa a cikin mai watsawa shine iyakance bandwidth na siginar fitarwa zuwa mafi ƙanƙanta, ta yadda za a iya watsa bayanan da ake buƙata a saurin da ake buƙata.

Me yasa matattarar Mitar Rediyo suke da mahimmanci?

Ana amfani da matatun RF don rarraba mitocin sigina, amma menene ya sa su da mahimmanci? A takaice, masu tace RF na iya tace surutu waɗanda zasu iya shafar inganci ko aikin kowane tsarin sadarwa ko rage tsangwama na sigina na waje. Rashin ingantaccen tacewar RF na iya lalata watsa mitar sigina, kuma a ƙarshe na iya lalata tsarin sadarwa.

Don haka, matattarar RF suna taka muhimmiyar rawa a tsarin sadarwar mara waya (watau tauraron dan adam, radar, tsarin wayar hannu, da sauransu). Idan ya zo ga aikin motocin marasa matuƙa (UAS), mahimmancin matatun RF a bayyane yake. Rashin ingantaccen tsarin tacewa zai shafi UAS ta hanyoyi da yawa, kamar:

Za a iya rage kewayon sadarwa zuwa tsangwama da abubuwan muhalli na waje suka haifar. Bugu da ƙari, samun yawan siginar RF a cikin sararin samaniya na iya haifar da mummunar lalacewa ga tsarin sadarwar UAV. Sigina na mugunta daga wasu dandamali sun haɗa amma ba'a iyakance su zuwa:; Ayyukan siginar Wi-Fi mai ƙarfi da sauran tsarin sadarwar da ke aiki a cikin UAS.

Katsewa daga wasu hanyoyin sadarwa za su katse tashar sadarwar UAS, ta yadda za a rage ko iyakance kewayon sadarwar irin waɗannan tsarin.

Tare da madaidaicin tace RF, tsangwama na waje da tsoma bakin siginar da tsarin sadarwa na kusa ke haifarwa ana iya kawar da su cikin sauƙi. Wannan yana kiyaye ingancin mitar siginar da ake so yayin da sauƙin tace duk mitocin siginar da ba'a so.

Bugu da kari, matatun RF suma suna taka muhimmiyar rawa a yanayin wayar hannu. Idan ya zo ga wayoyin hannu, suna buƙatar takamaiman adadin madafan mitar don yin aiki yadda ya kamata.
