Abstract:
Enhanced RF system measurement including measurement of reflected power of a transmission system using two directional couplers configured to couple reflected power (e.g., isolate forward power). The directional couplers may be placed at a distance of ¼ wave separation and measurements from the two directional couplers may be averaged to obtain a reflected power for the transmission path. The enhanced measurement of reflected power may be used to obtain a more accurate VSWR or return loss measurement. An indication of the reflected power (e.g., VSWR, return loss, etc.) may be fed back to a source, which may adjust transmit power based on the measured VSWR to achieve a certain amount of power conveyed to the load (e.g., target radiated power from an antenna, etc.). Error conditions may be detected and the source may terminate transmission to prevent potential adverse operating conditions.
