Power Combiners are 4-port devices. When the appropriate port is terminated, these devices can be used to combine the output power of 2 amplifiers to a single output port.

More than one coupler can be used to combine a large number of amplifiers. These units have been designed to handle high power levels greater than that of magic tees, and offer isolation in excess of 26dB between the input and output ports.


  • Combine same or different frequencies within the waveguide band
  • Combine same or different power levels within the waveguide band
  • Coupling ratios may vary from symmetrical (3dB) to assymetrical
  • Can handle full waveguide power
  • Can replace magic tees
