I have modified Henrik's original directional coupler. Instead of two couplers in series with terminated isolation ports I decided to have only one coupler with RSSI detectors on both coupled and isolated port. This way I hope to be able to measure both output and reflected power from the same component, which is useful for VSWR estimation.
