◆Innovative Technology Eliminates Sudden Big Reflection
◆The Application Advantages of Yantel Variable Attenuator in RF Test System
|
|
|
Features
● Using advanced microstrip technology, ultra-small size
● High RF performance, ultra-competitive price
● Wide frequency range: DC to 6GHz
● Small reflection coefficient（Max. VSWR）: 1.1～1.5
● Low attenuation tolerance,Low ion loss
● Adjusting the transmitting (receiving) distance of RF signal precisely.Adjusting accuracy is limited to 5cm.
● Wide attenuation values available are 1, 2, 3, 4, 5, 6, 8, 9, 10and 12dB
● High adjustment accuracy
● Average power range: 2W, 5W
● Impedance: 50Ω or 75Ω
● Switch repeatability avg.> 10000 operations (5000 cycles)per switch.
● PC(Polycarbonate)switch,operating termperature of 120℃ is available.
● It adopts an innovative technology, and thus it eliminates sudden big reflection in attenuators when attenuation is being adjusted, preventing the preliminary RF circuit (such as power amplifier) from being burnt, and keeping the system stable
● PC(Polycarbonate)switch,operating termperature of 120℃ is available.
● Attenuation values are adjustable in power-on state,test data can be read continuously,no interruption.
● Connector Type:SMA,N,F,BNC,TNC etc.available.
● Connector Position:Back Connectors or Left&right Connectors.
|
 Abrupt change of refection occurs in traditional variable
attenuator when adjusting attenuation,resulted in RF
power amplifier being burnt.
