Abstract:
A low noise converting apparatus comprising:a plurality of first-stage low noise amplifying means each provided in a path of a respective reception signal of a polarized wave received from a plurality of satellites; control means for selectively making one of said plurality of first-stage low noise amplifying means operative in accordance with a satellite selected from said plurality of satellites and the polarized wave of a radio wave therefrom; a single next-stage low noise amplifying means for further amplifying an output of a selected one of said plurality of first-stage low noise amplifying means; coupling means for coupling said plurality of first-stage low noise amplifying means and said single next-stage low noise amplifying means; and frequency converting means for frequency converting an output of said single next-stage low noise amplifying means and producing a converted output signal, wherein said coupling means includes extending portions extended in strip conductor shapes from outputs of said plurality of first-stage low noise amplifying means and an extending element extended in a strip conductor shape from an input of said single next-stage low noise amplifying means, said extending portions and said extending element being arranged so as to closely face each other.
