Thin fim Coaxial attenuator

  • 1. Overview
The main indicators of this series of coaxial fixed attenuator refer to the bw-s1w2 + series of MINI company. With frequency DC ~ 18GHz and maximum input power of 2W, it has the following characteristics: wide working frequency band, low standing wave ratio, flat attenuation, strong impulse resistance and burning resistance.
