A 10-way power divider based on a transducer and a radial junction operating in the circular TM01 mode [PDF]
, 2019 This work presents a 10-way Ku-band power divider using a mode transducer and a radial junction connected by an overmoded circular waveguide operating in the TM 01 mode. The circular symmetry of this mode has been exploited to obtain a power divider with
