A radio frequency (RF) power detector is disclosed. The RF power detector includes an envelope detector having an RF signal terminal and a current mode terminal, wherein the envelope detector is configured to detect peak voltages of an RF signal at the RF signal terminal. Further included is a detector current mirror having a first mirror branch coupled to the current mode terminal and a second mirror branch configured to create a detector current that is proportional to a branch current through the first mirror branch in response to peak voltages detected by the envelope detector.
