Multilayer Micromachined Cavity Filter

Typical APPLICATIONS:
Space application in Ka band

  • Typical operation frequencies: 25 ÷ 35 GHz
  • Typical fraction bandwidth: up to 3÷4%
  • Volume and mass saving with respect to reference technology: >50%
  • Achievable unloaded Q-factor: up to 1000
  • Thermal range of operation: -30 ÷ + 70°C
  • Possible RF interconnection: SMT, wire bonding

Multilayer stack, allows the possibility to increase the Q-factor by increasing the height of the filter.

Alternative design concepts allow for cavity filters up to 100GHz.
