Abstract: A high-power, frequency-tunable, harmonic filtering system for multiple operating frequencies includes a first SPMT switch circuitry, a second SPMT switch circuitry, and high-power, frequency-tunable harmonic filters (HFHFs). The first SPMT single-pole terminal is configured to receive a high-power RF input signal. The second SPMT single-pole terminal is configured to output a high-power RF output signal. Each of the HFHFs is connected to a respective one of the first SPMT multi-throw terminals and a respective one of the second SPMT multi-throw terminals. Each of the HFHFs is interposed between the respective first and second multi-throw terminals along a respective RF signal pathway between them. Each operating frequency is associated with one of the HFHFs. The respective operating frequency is associated with one of multiple cutoff frequencies of the respective HFHF.
