RF & Microwave Attenuator and Linearizers

APITech's Attenuator products are offered in both Digital and Voltage Variable configurations. Formerly the product line from Amplifonix, Digital Attenuators are available in frequency ranges from 10 to 2000 MHz. Integrated TTL drivers simplify system integration. Some features include:

  • Wide Range of Attenuation Options
  • Quality Assurance
  • Integrated Solutions

Digital attenuation steps are available from 0.1 dB to 63.5 dB. When voltage variable gain control is required, Voltage Variable Attenuators (VVAs) are available in frequency ranges from 5 to 2000 MHz.
