Abstract
A linear multiband waveguide feed network device, which includes a first section, a second section, a third section and an inverse-ridge receive (Rx)-reject filter. The second section is coupled to the first section via a first split-plane. The third section is coupled to the second section via a second split-plane. The inverse-ridge Rx-reject filter is implemented as a first half-portion and a second half-portion. The first half-portion and the second half-portion are implemented in the second section and the third section, respectively. The first split-plane and the second split-plane are on a zero-current region of the device.
