Tri-frequency feedchain and devices and methods for a tri-frequency feedchain

An orthomode transducer for separating an intermediary signal on a single waveguide, the intermediary signal being of an intermediary signal frequency band comprising a first signal frequency band and a second signal frequency band, the orthomode transducer configured to:

• separate the intermediary signal to obtain at least six split intermediary signals;
• and
• provide each split intermediary signal to a corresponding reject filter of a tri-band waveguide, the tri-band waveguide configured to combine the split intermediary signals with a third signal of a third frequency band;
• and
• wherein the first, second, and third frequency bands do not intersect.

A method of combining a at least three frequency bands on a single waveguide, the method comprising:

• separating, via a separating component, an intermediary signal into six split intermediary signals, wherein the six split intermediary signals are of substantially equal amplitudes;
• providing each of the six split intermediary signals to a different one of six reject filters, each respective reject filter connected to and positioned about a turnstile;
• at each respective reject filter:
• filtering the received split intermediary signal to obtain a filtered intermediary signal, wherein the intermediary signal is of an intermediary signal frequency band comprising a first signal frequency band and a second signal frequency band;
• and
• outputting the filtered intermediary signal to the turnstile;
• combining, by the turnstile, the filtered intermediary signals from each of the six reject filters and a third signal of a third signal frequency band into a combined signal;
• and
• outputting the combined signal.
