Digital Controlled Attenuators
Digital Controlled Attenuator ke karolo ea microwave e ka laolang palo ea phokotso ka matshwao a dijithale.
Molao-motheo oa eona oa ts'ebetsong ke ho laola ho fokotseha ha letšoao ka ho lokisa boemo ba karolo ea ka hare kapa boholo ba pontšo ea ho kenya letsoho, ho fetola boleng ba ho hanyetsa.Ha ho bapisoa le li-attenuators tse tloaelehileng tsa mochini le li-resistant tse fapaneng.
Li-attenuators tse laoloang ke dijithale li na le melemo e latelang:
1. Ho nepahala ho phahameng: The attenuator ea taolo ea dijithale e ka finyella taolo e phahameng ka ho fetisisa ea ho fokotseha ka ho laola digital, hangata ho fihlela ho nepahala ha 0.1dB kapa ka tlase.
2. Broadband: Li-attenuators tse laoloang ke dijithale hangata li sebetsa sebakeng sa GHz kapa esita le THz mme li na le bandwidth e pharaletseng.
3. Sebaka se seholo sa matla: Setsi sa taolo ea dijithale se ka finyella sebaka se feto-fetohang ho tloha ho 0dB ho ea ho 60dB kapa ho feta, 'me sebaka sa phetoho se pharaletseng.
4. Taolo e hlophisitsoeng: The attenuator ea taolo ea dijithale e ka hlophisoa ka li-interface tsa digital tse kang SPI le I2C, tse nang le maemo a phahameng a feto-fetohang.
Li-attenuators tse laoloang ke dijithale li sebelisoa haholo-holo mafapheng a kang tlhahlobo ea microwave, radar, puisano le puisano ka satellite.Ho nka mohlala oa kopo ea tlhahlobo, mochine oa taolo ea dijithale o ka sebelisoa ho lokisa matla a lets'oao la tlhahlobo ho lekanya kutlo le ho lekana ha DUT (Sesebelisoa se Tlas'a Teko);E ka sebelisoa ho lekanya sistimi ea liteko ho netefatsa ho nepahala le ho tsitsa ha eona;E ka sebelisoa bakeng sa maemo a tlhahlobo ea papiso ho lekola ts'ebetso e khahlanong le tšitiso ea sistimi khahlano le tšitiso e fapaneng le maemo a mocha.
Qualwavee fana ka sehlopha se sephara le li-attenuator tse laoloang ke dijithale tse matla ho fihla ho 40GHz.Mohato o ka ba 0.25dB mme sebaka sa attenuation se ka ba 100dB kapa ho feta.Li-attenuators tsa rona tse laoloang ke dijithale li na le boleng bo botle le ts'epahalo e phahameng, Ka linomoro tsa likarolo tse fetang 70, tse ka fihlelang litlhoko tsa bareki ba fapaneng mme li sebelisoa haholo libakeng tse ngata.
