Abstract

PURPOSE:To simultaneously receive a couple of orthogonal modes by providing a microwave circuit blocking vertical and horizontal mode waves propagated in a waveguide through separate short-circuit and coupling with the blocked vertical and horizontal mode waves. CONSTITUTION:The vertical mode microwave inputted from a circular waveguide 1 is short-circuited by a vertical mode filter 2 to block it and it is extracted from the waveguide 1 by a coupling post 5 and returned into the waveguide 1 from the post 7 via a high frequency amplifier 11. The microwave is forwarded further in the waveguide 1 and led externally from a post 9 and inputted to a frequency converter 13. The filter 3, the posts 6, 8 and the high frequency amplifier 12 act similarly like the horizontal mode wave and the wave is led to a frequency converter 14 from the post 10. The oscillated frequency of the frequency converters 13, 14 is selected lower than the received microwave frequency and shows a cut-off band to the waveguide 1. Thus, a couple of mode signals to be orthogonal are received simultaneously by a simple installation.
