The SDP coaxial attenuators cover all the cellular wireless bands in the DC-3 GHz. SDP offers solutions with different average power levels and attenuation range. Low power attenuators are bidirectional but high power ones are unidirectional. Attenuators are used in a DAS (distributed antenna system) to adjust the output power. In particular, when an active DAS system are fed using an existing base station the power level are reduced to be able to be transferred by fiber optics.

Features

  • Wide range of attenuation values (3 dB-40 dB)
  • Low cost versions are available
  • Covering all the cellular frequency bands (DC -3000 MHz)
  • Different power handling values (25-200 W)
  • Low PIM (<-165 dBc) options are available
