C / Ku band multi-polarization antenna feed OMT with frequency range selector
This antenna feed provides simultaneous reception of signals of two opposite circular or two orthogonal linear polarizations in the range of 3.4 - 4.8 GHz and two opposite circular or two orthogonal linear polarizations in the range of 10.7 - 12.75 GHz .
The outputs of the microwave converter units can be made connected to the WR-229 flange (accordingly to the range of 3.4 – 4.8 GHz (2 outputs)) and WR-75 (the range of 10.7 – 12.75 GHz (2 outputs)).
The two ports of the ku port receive in an orthogonal manner, with vertical and horizontal polarization. The vertical and horizontal positions of the two receiver ports can be switched 90 degrees.
Main parameters
VSWR on device outputs:
• in the range of 3.4 - 4.8 GHz: no more than 1.35;
• in the range of 10.7 - 12.75 GHz: no more than 1.35.
Total losses, dB:
• in the frequency range of 3.4 - 4.8 GHz: no more than 0.3;
• in the frequency range of 10.7 - 12.75 GHz: no more than 0.5.
