Abstract (en)

[origin: EP0196081A2] The invention relates to a device for the combination without r.f. power loss of two or more microwave transmitters running in parallel and with any power ratio, comprising as basic components in cascade connection and with the interposition of rotative joints and, where necessary, of transition connections with the rotative joints, a first orthogonal mode input transducer (OMT1), a first rotative polarizer (P1) which can receive at the input an elliptically polarized field and supply at the output a linearly polarized field, a second rotative polarizer (P2) which can receive at the input a linearly polarized field and supply at the output a linearly polarized field which, however, in an intermediate part has got a transformation into a circular polarization, a second orthogonal mode output transducer (OMT2) and two motors (M1, M2) commanding the rotational motions of said two polarizers (P1, P2) and being controlled by a computer which gets monitoring data from a detector diode (DR) connected with the transversal branch of said output transducer.
