QHA feeder using wilkinson power divider with 90 degree shifted phase

摘要

The present invention is to provide a feeder with QHA Wilkinson power divider with 90 degrees phase difference signal is applied to the input port; When the signal of the input port 0 is applied also to the first output port for outputting a signal having a phase difference; And the second output port for outputting a signal having a phase difference of 90 degrees by a / 4 transmission line when the signal applied to the input port; And the first output port and to the second output port associated with the / 2 transmission line; If the signal applied to the input port a third output port for outputting a signal having a phase difference of 180 degree in by the / 2 transmission line; And if the signal to the input port is the / 2 second output port for outputting signals having a phase difference 270 by a transmission line; by comprising a relatively simple, in order to apply to a portable satellite communication device QHA , it is possible to offer a design that can be the power supply circuit to a smaller size.
