delta mecannica 1660 6 filter

Delta Meccanica 1660-6

The Delta Meccanica 1660-6 is a 250W DMB/DAB Filter with 6 Cavities and cross-coupling offering superior performance at an affordable price. Unlike an analogue radio signal, the digital DC DAB current can transmit an impressive amount of information. The two extra band-reject filters ensure enhanced isolation and an increased insertion loss due to the amount of dissipated energy because of the extra sections..

  • Power range from 250W up to 3KW
  • Temperature compensation (INVAR)
  • Extremely stable
  • Low insertion loss
  • Silver-plated components
  • Rugged finishing
  • Natural convection cooling
  • Custom-tailored mask available
