5 - 45 GHz Variable Attenuator

Currently Viewing:

AMMC-6630 MMIC is a monolithic, voltage variable, GaAs IC attenuator that operates from 5-45 GHz. It has a distributed topology and helps to absord parasiticeffects of its series and shunt FETs to make it broadband.


  • Wide Frequency Range 5-45 GHz 
  • Attenuation Range 20dB
  • Positive Singe Pin Control Voltage
  • Unconditionally Stable 


  • Microwave Radio Systems
  • Satellite VSAT, DBS up/down Link 
  • WLL and MMDS loops
  • Broadband Wireless Access (including 802.16 and 802.20 WiMAX)
