The X-band section of this joint has three channels:two for high power and one for low power,and has a frequency bandwidth of Δf = 1GHz,while its L-band section has two channels both for high power and has a frequency bandwidth of Δf= 140MHz.
該關(guān)節(jié) X 波段為三路,(頻率)帶寬為:△f=1GHz,兩路高功率通道,一路低功率通道;L 波段為兩路,(頻率)帶寬為:△f =140MHz,兩路均可用于高功率通道。
