Clarke & Severn Electronics  presents the new Yantel VAS miniature variable attenuators designed to operate in a wide frequency range of DC to 6000MHz.
 
Yantel VAS miniature variable attenuators use advanced microstrip technology to achieve high RF performance in an ultra-small package. The wide attenuation range of 0 to 90db is achieved using a switching combination of the following values: 1, 2, 3, 4, 5, 6, 8, 9, 10 and 12 db.
 
The operating temperature range of -40°C to +85°C and above makes the attenuators ideally suited for broadcast, WLAN systems, radar, satellite, GPS, lab testing and mobile communication stations.
 
Key features of Yantel VAS miniature variable attenuators:

  • Each switch has a lifecycle of greater than 10000 operations
  • Attenuation values adjustable in a power-on state allowing test data to be read continuously without interruption
  • Eliminates any sudden large reflections in attenuators when attenuation is being adjusted
  • Prevents preliminary RF circuit components from being burnt and keeps the system stable
  • Power handling is 2 watts
  • Comes in 50ohm (standard) or 75ohm impedance with a VSWR of 1.1-1.8
  • Low attenuation tolerance and low insertion loss with the option of BNC, F, N or SMA connectors
