RF Yakakwirira Simba BroadBand Test Systems 75 ohms Attenuators
A 75 ohm attenuator imhando yeattenuator yakatumidzwa kukanganiswa kwayo kwe75 ohms.
Icho chinhu chinoshandiswa kudzora simba rechiratidzo chedunhu, A 75 ohm attenuator inodzivirira kuwedzeredza uye kukanganisa kwechiratidzo, uye inodzivirira kutadza kunokonzerwa nekuremerwa kwechiratidzo.
Hunhu hwayo hukuru hunosanganisira:
1. Impedance inofananidzwa: Iyo 75 ohm maitiro impedance inofanana neiyo impedance yechiratidzo chekufambisa mutsara wemidziyo yevhidhiyo, kutepfenyura kweterevhizheni uye tambo yeterevhizheni, nokudaro kuderedza kuratidzwa uye kurasikirwa kwechiratidzo chekufambisa.
2. Kukanganisa kwakaderera: Attenuator inogona kuderedza simba rechiratidzo pasina kuunza kumwe kukanganisa kana kupindira kwechiratidzo.
3. Kuvimbika kwepamusoro: Pamusana pekuti attenuators anonyanya kuita zvinhu uye haana zvikamu zvinofamba, akavimbika zvikuru uye haadi kugadzirisa kana kuchinjwa.
75 ohm attenuators anowanzoshandiswa mune zvinotevera maapplication:
1. Mutambo dzeterevhizheni terevhizheni uye dhijitari terevhizheni network, inoshandiswa kugadzirisa simba rechiratidzo uye kuderedza kuratidzwa kwechiratidzo nekurasikirwa.
2. Panguva yekugadzirwa uye kuendesa kwepamusoro-kugadziriswa uye mavhidhiyo akakwirira-tsanangudzo, chengetedza simba rechiratidzo uye chengetedza kutendeuka kwehutano.
3. Mukutepfenyura uye terevhizheni masisitimu ekutumira masaini, midziyo inogadzirisa simba rechiratidzo kuti ienderane chaiyo yakagoverwa masaini magadzirirwo uye kuwedzera chiratidzo chechiratidzo.
4. Mumaantenna eterevhizheni, anoshandiswa kuenzanisa simba rechiratidzo pakati pemaamplifiers neantenna.
Qualwaveinopa akasiyana akanyanya kunaka uye yakakwirira simba coaxial 75 ohms attenuators inovhara frequency renji DC ~ 3GHz, inogona kuenzaniswa neBNC, F-mhando, uye N-mhando yekubatanidza. Iyo attenuation inonyanya kubva pa1 kusvika ku40dB. Iwo attenuators ane Yakanyanya kurongeka uye yakakwirira simba, yakavimbika mhando, zvigadzirwa zvakawanda zvinoenderana neROHS, zvinogona kusangana nezvinodiwa zvakasiyana zvevatengi.
