ABSTRACT:
The present invention is a low series impedance directional power detector, which may be used to measure either forward or reverse power in a radio frequency (RF) circuit. The directional power detector includes current detection circuitry to directionally measure current, voltage detection circuitry to measure voltage, and combining circuitry to combine the directional RF current measurements and the RF voltage measurements into a combined RF measurement, which is indicative of directional power. The current detection circuitry and voltage detection circuitry apply any phase-shifts that are needed to detect power in the direction of interest and ignore power in the opposite direction when the directional power detector is presented with a complex load.
