Development of C-band Mid-Power Meter by Single Hole Di-coupler

According to research the microwave mid-power meter that used for spots under testing and calibrating,this text introduces a kind of C-band and pass type wave-guide power meter,including one single hole di-coupler formed of wave-guide subsections and one semiconductor thermocouple power meter,which of design theory and constitutes,and those analysis of testing data and measurement uncertainty.The test data shows that the designed mid-power meter has good much accurate measurement.
