Load ɗin RF Dummy na'ura ce da ake amfani da ita don kwaikwayi nauyin lantarki yayin gwaji. Yana iya gwada kayan aikin RF ɗin ku ba tare da tsoma baki tare da igiyoyin rediyo ba.

Ko kuna da gogewa a fagen RF ko a'a, kuna buƙatar nauyin RF ɗin dummy don gwada kayan aikin RF don tabbatar da gidan rediyo yana aiki akai-akai. Amma shin kun san yadda ake gane mafi kyawun nauyin RF ɗin dummy yayin fuskantar zaɓi daban-daban a kasuwa?

Don taimaka muku siyan kayan RF ɗin da ya dace kuma mai rahusa, mun nuna mahimman maki 6 don la'akari. Bari mu fara!

1# Ƙididdigar Wutar Lantarki

Lokacin da kake gwada kayan aikin RF, za ku sami nauyin RF ɗin yana gudana akai-akai. Don yin aiki cikin aminci, don haka, yakamata ku mai da hankali kan ko ƙimar wutar lantarki ta gamsu da buƙatunku maimakon mafi girman ƙarfin.

Yawancin lokaci, ana ba da shawarar cewa ƙarancin wutar lantarki na RF dummy load (a ƙarƙashin 200w) don tashoshin rediyo mai son da ƙananan tashoshin rediyo ne yayin da babban ƙarfin dummi na RF na ƙwararrun tashoshin rediyo ne.

2# Yawan Mita

Ya kamata ku lura ko kewayon mitar ya rufe bukatun ku. Yawancin lokaci, nauyin dummi na RF yana da faffadan mitar mitoci kamar DC (wato 0) zuwa 2GHz, don haka ba lallai ne ka damu da shi da yawa ba. 

3# Ƙimar Ƙarfafawa

Kamar tsarin eriya, nauyin RF dummy ya kamata ya dace da tushen RF shima. Don haka, ƙimar impedance mai ɗaukar nauyi yakamata ta zama iri ɗaya da eriya ko layin watsawa.

The RF dummy load 50 Ohm da 75 Ohm su ne daidaitattun nau'ikan da muke amfani da su. Kuma nauyin RF dummy 50 Ohm yawanci yana dacewa da tushen RF mafi kyau a cikin yanayin RF.

4# Tsarin Warkar da Zafi

Manufar nauyin RF dummy shine maye gurbin eriya da karɓar makamashin RF. Za a juya makamashin da aka sha ya zama zafi a cikin nauyin dummy, saboda haka, ya kamata ku kula da tsarin zubar da zafi.

Yawanci, nauyin dummy yana dogara ne akan heatsinks, kuma ana yin su daga alloy, aluminum, da dai sauransu, kuma irin wannan nau'in dummy shi ake kira dry heatsink load. Bayan tsarin tarwatsewa a sama, akwai wasu nau'ikan dummi na RF waɗanda ke watsar da zafi ta ruwa, gami da ruwa, mai da iska, da sauransu. 

A cewar injiniyanmu Jimmy, sanyaya ruwa shine hanya mafi kyau don watsar da zafi amma yana buƙatar kulawa mai rikitarwa.

5# Nau'in Haɗa

Haɗa tushen RF tare da nauyin RF ɗin dummy shine mataki na ƙarshe na shiri. Duk abin da kuke buƙatar yi shine tabbatar da haɗin haɗin haɗin. 

The RF dummy load yana da nau'ikan masu haɗawa iri-iri, gami da nau'in N, nau'in BNC, da sauransu. Kuma suna da girma dabam dabam kuma.

Kammalawa

Da yake magana game da wanne, an sanye ku da ilimin don ɗaukar mafi kyawun nauyin RF dummy. Madaidaicin nauyin juzu'i na RF gabaɗaya shine tushe na haɓaka tashar rediyo. 

Idan kuna buƙatar ƙarin taimako wajen haɓaka gidan rediyon ku, me zai hana ku sami ingantaccen tambarin taimako? Misali, FMUSER ba zai iya samar muku da kayan dummi na RF ba tare da babban kewayon ƙimar wutar lantarki daga 1W zuwa 20KW, sanye take da nau'ikan masu haɗa nau'ikan nau'ikan haɗin kai da hanyoyin watsar da zafi waɗanda ke biyan bukatunku daban-daban.

Idan kuna son ƙarin bayani game da nauyin RF dummy, da fatan za a iya tuntuɓar mu!
