COMTECH PST Component Division introduced a new digital attenuator for applications in UHF band.  The design operates over the 400 to 500 MHz frequency range intended for use in military or commercial applications. The attenuator provides 0 to 60 dB of range. The accuracy achieved is exceptional when changing attenuator steps. Switching speed is very fast when attenuation needs to be changed. Other frequencies, attenuation ranges and performance characteristics can be achieved for other applications.


  • TTL Controlled Attenuation Level
  • 4 Bit Attenuation Control
  • 60 dB Attenuation Range
  • Amplitude/Phase Matched State to State
  • Excellent Attenuation Accuracy
  • Fast Switching Speed
  • +5 VDC and -15 VDC input
