Iyo Attenuator chikamu chemagetsi chinoshandiswa zvakanyanya mumidziyo yemagetsi, uye basa rayo guru nderekupa attenuation. Icho chinhu chinopedza simba, chinoshanduka kuita kupisa mushure mekushandisa simba. Zvinangwa zvaro zvikuru ndezvi: (1) Gadzirisa saizi yechiratidzo mudunhu; (2) Mukuenzanisa nzira yekuyera dunhu, inogona kushandiswa kuverenga zvakananga kukosha kweiyo attenuation yetiweki yakaedzwa; (3) Kuvandudza impedance yekufananidza, kana mamwe masekete achida Kana yakagadzikana mutoro impedance ikashandiswa, attenuator inogona kuiswa pakati pedunhu uye chaiyo mutoro impedance kuvharira shanduko ye impedance. Saka kana uchishandisa attenuator, ndezvipi zvinhu zvinoda kutarisirwa?
Ngatizvizivise zvakadzama pazasi:
1. Frequency mhinduro: iyo frequency bandwidth, inowanzoratidzwa mu megahertz (MHz) kana gigahertz (GHz). General-chinangwa attenuators kazhinji vane bandwidth inosvika 5 GHz, ine yakakura bandwidth ye50 GHz.
2. Attenuation range uye chimiro:
Attenuation range inoreva chiyero chekuyeresa, kazhinji kubva pa3dB, 10dB, 14dB, 20dB, kusvika pa110dB. Iyo attenuation fomula ndeiyi: 10lg (inopinza/inobuda), semuenzaniso: 10dB maitiro: kupinza: kubuda = attenuation akawanda = gumi nguva. Chimiro chacho chinowanzo kupatsanurwa kuita mafomu maviri: yakagadziriswa proportional attenuator uye nhanho proportional inogadziriswa attenuator. A Fixed attenuator inoreva attenuator ine reshiyo yakatarwa yakawanda mune imwe frequency renji. Nhanho attenuator ndeye attenuator ine imwe yakagadziriswa kukosha uye yakaenzana interval inogadziriswa reshiyo. Iyo yakakamurwa kuita yemanyorero nhanho attenuator uye programmable nhanho attenuator.
3. Fomu yekubatanidza musoro uye saizi yekubatanidza:
The connector type inokamurwa kuva BNC type, N type, TNC type, SMA type, SMC type, etc. Panguva imwecheteyo, chimiro chekubatanidza chine marudzi maviri: murume nemukadzi.
Saizi yekubatanidza yakakamurwa kuita metric uye imperial masisitimu, uye zviri pamusoro zvinotemerwa zvinoenderana nezvinodiwa zvekushandisa; kana mhando dzekubatanidza dzichida kubatanidzwa, iyo inoenderana yekubatanidza adapta inogona kuve yakashongedzerwa, semuenzaniso: BNC kune N-mhando yekubatanidza, nezvimwe.
4. Attenuation index:
Attenuation zviratidzo zvine zvakawanda zvinodiwa, kunyanya zvinotevera zvinhu: attenuation kunyatsoita, kutsungirira simba, hunhu impedance, kuvimbika, kudzokorora, nezvimwe.
Semugadziri weattenuators, Jingxin inogona kukutsigira nemhando dzakasiyana dzeattenuators zvinoenderana neRF mhinduro yako.
