The frequency range of circular waveguides in different frequency bands varies according to their diameter. For example, in TE11 mode, a circular waveguide with a diameter of 22.86 mm operates at 7.3-10 GHz. Choose the appropriate diameter to match the required frequency range to ensure low-loss transmission. S-Band Characteristics At 3AM, ESA alerted us about
