Each unit has a waveguide cover flange interface and a connector. All flange interfaces are compatible with MI Technologies' family of MI-212 Standard Gain Horns and all of MI Technologies' probes and feeds. 

  • Covers waveguide bandwidths from 350 MHz to 90 GHz
  • All flange interfaces are compatible with the MI-212 Family of Standard Gain Horns and all of MI Technologies' probes and feeds
  • Ideal for use with our Standard Gain Horns and Feeds, offering a convenient transition between waveguide and coaxial transmission line

Assembly

MI-211-Assembly 

For frequencies up to 90 GHz, MI-211 Family of Coax-to-Waveguide Adapters (CWGA) are available to mate with the MI-212 Family of Standard Gain Horns. An MI-211 CWGA can be ordered pre-assembled to the MI-212 SGH by specifying model MI-210.
