Radio frequency power sensor having a non-directional coupler

An RF power monitoring system comprising:

• a first input power sensor, a second input power sensor, an output power sensor, and a channel power meter;
• said first input power sensor is configured to measure a pre-combiner RF power level for a first channel on a first channel transmission line and provide the measured pre-combiner RF power level for the first channel to the channel power meter;
• said second input power sensor is configured to measure a pre-combiner RF power level for a second channel on a second channel transmission line and provide the measured pre-combiner RF power level for the second channel to the channel power meter;
• said output power sensor is configured to measure a post-combiner RF power level for the first channel on a combined channel transmission line and provide the measured post-combiner RF power level for the first channel to the channel power meter;
• and
• said output power sensor is further configured to measure a post-combiner RF power level for the second channel on the combined channel transmission line and provide the measured post-combiner RF power level for the second channel to the channel power meter.
