VAS0655H*2*

Miniature Variable Attenuator

International invention patent

Manual Step Attenuator

 DC to 4GHz

 0 to 55.5dB in 0.5dB Step

 2 Watt

 Connector Type:SMA,N,TNC,F,BNC etc.

available.

Features



Using advanced microstrip technology, ultra-small size

Attenuation values are adjustable in a power-on state, no

sudden big reflection.

It adopts an innovative technology, and thus it eliminates

sudden big reflection in attenuators when attenuation is

being adjusted, preventing the preliminary RF circuit from

being burnt, and keeping the system stable

Step values: 0.5dB, 1dB, 2dB, 4dB,8dB,10dB,10dB,

10dB, 10dB
