Using advanced microstrip technology, ultra-small size
Attenuation values are adjustable in a power-on state, no
sudden big reflection.
Step Value
Insertion loss at 0dB (typ.)
SMA connector
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: 3dB,6dB
