Abstract :
In this paper, an improved power divider/combiner based on Y-structure waveguide is proposed at ka-band (26-40 GHz). To widen the bandwidth of the divider/combiner, a stepped-impedance waveguide transformer is used, and a vertical resistive card is inserted into the divider/combiner to realize high isolation. According to EM simulations, the power divider/combiner illustrates a 42.4% effective bandwidth (ranging from 26 to 40 GHz), the return loss is better than -24 dB, and the isolation is better than -21 dB. This structure has properties of not only a wide band, low insertion loss and high output power, but also a small size, a high power combining efficiency and efficient heat sinking, and has potential for millimeter-wave broad-band high power combination.
