I-RF Dummy Load iyithuluzi elisetshenziselwa ukulingisa umthwalo kagesi phakathi nokuhlolwa. Ingahlola okokusebenza kwakho kwe-RF ngaphandle kokuphazamisa amaza omsakazo.

Kungakhathaliseki ukuthi unolwazi emkhakheni we-RF noma cha, uzodinga i-RF dummy load ukuze uhlole okokusebenza kwe-RF ukuze uqinisekise ukuthi isiteshi somsakazo sisebenza ngendlela evamile. Kepha uyazi ukuthi ungawubona kanjani umthwalo we-RF dummy ongcono kakhulu lapho ubhekene nokukhetha okuhlukahlukene emakethe?

Ukukusiza ukuthi uthenge umthwalo we-RF dummy ofanele futhi ongabizi kakhulu, sibonisa amaphuzu angu-6 abalulekile okufanele uwacabangele. Ake siqale!

1# Isilinganiso samandla

Uma uhlola okokusebenza kwe-RF, uzothola i-RF dummy load isebenza ngokuqhubekayo. Ukuze usebenze ngokuphepha, ngakho-ke, kufanele ugxile ekutheni isilinganiso samandla saneliswa yini ngezidingo zakho kunamandla aphezulu.

Imvamisa, kuyatuswa ukuthi amandla aphansi we-RF dummy load (ngaphansi kuka-200w) oweziteshi zomsakazo ezisanda kufunda kanye neziteshi zomsakazo ezinamandla aphansi kuyilapho amandla aphezulu e-RF dummy load eyeziteshi zomsakazo eziqeqeshiwe.

2 # Ibanga Lemvamisa

Kufanele uqaphele ukuthi ububanzi befrikhwensi buhlanganisa izidingo zakho. Ngokuvamile, i-RF dummy load ine-band frequency band ebanzi njenge-DC (okungu-0) ukuya ku-2GHz, ngakho-ke akufanele ukhathazeke ngayo kakhulu. 

3# Amanani Wokuphazamiseka

Njengezinhlelo ze-antenna, umthwalo we-RF dummy kufanele ube nomdlalo omuhle nemithombo ye-RF futhi. Ngakho-ke, inani le-dummy load impedance kufanele lifane ne-antenna noma ulayini wokudlulisa.

I-RF dummy load 50 Ohm kanye ne-75 Ohm yizinhlobo ezijwayelekile esizisebenzisayo. Futhi i-RF dummy load 50 Ohm ivamise ukufana nemithombo ye-RF kangcono kakhulu ezimeni ze-RF.

4# Uhlelo Lokukhipha Ukushisa

Inhloso yomthwalo we-RF dummy ukuvala uthi bese uthola amandla e-RF. Amandla amuncwa azoguqulwa abe ukushisa kumthwalo we-dummy, ngakho-ke, kufanele unake uhlelo lokukhipha ukushisa.

Imvamisa, umthwalo we-dummy uncike kuma-heatsink, futhi enziwe nge-alloy, i-aluminium, njll., futhi lolu hlobo lomthwalo we-dummy lubizwa ngokuthi umthwalo owomile we-heatsink. Ngaphandle kwesistimu yokulahla ngenhla, kukhona imithwalo ye-RF dummy echitha ukushisa ngoketshezi, okuhlanganisa amanzi, uwoyela nomoya, njll. 

Ngokukanjiniyela wethu uJimmy, ukupholisa amanzi kuyindlela engcono kakhulu yokukhipha ukushisa kodwa kudinga ukulungiswa okuyinkimbinkimbi.

5# Izinhlobo zesixhumi

Ukuxhuma imithombo ye-RF ne-RF dummy load kuyisinyathelo sokugcina sokulungiselela. Odinga ukukwenza nje ukuqinisekisa ukuthi isixhumi sifaniswa. 

I-RF dummy load inezinhlobonhlobo zezinhlobo zezixhumi, okuhlanganisa uhlobo lwe-N, uhlobo lwe-BNC, njll. Futhi inosayizi abahlukene.

Isiphetho

Ukukhuluma ngakho, uhlonyiswe ngolwazi lokuthatha umthwalo we-RF dummy ongcono kakhulu. I-RF dummy load efanelekile ngokuvamile iyisisekelo ekwakheni isiteshi somsakazo. 

Uma udinga usizo olwengeziwe ekwakheni isiteshi sakho somsakazo, kungani ungatholi uhlobo oluthembekile ukuze uthole usizo? Isibonelo, i-FMUSER ayikwazi ukukunikeza kuphela imithwalo ye-RF dummy enohlu olukhulu lwezilinganiso zamandla ukusuka ku-1W ukuya ku-20KW, efakwe izinhlobo ezahlukene zezixhumi nezindlela zokukhipha ukushisa ezifeza izidingo zakho ezihlukene.

Uma ufuna okwengeziwe mayelana ne-RF dummy load, sicela ukhululeke ukuxhumana nathi!
