ENVELOPE DETECTOR, LINEARIZATION CIRCUIT, AMPLIFIER CIRCUIT, METHOD FOR DETECTING A MODULATION ENVELOPE AND WIRELESS COMMUNICATION UNIT

An envelope (100) detector for detecting a modulation envelope of a modulated signal. The envelope detector includes a sensor (102). The sensor has a sensor input (1021), for sensing a signal forming a measure for the amount of electrical power presented at the sensor input (1021). The sensor input...

Summary:An envelope (100) detector for detecting a modulation envelope of a modulated signal. The envelope detector includes a sensor (102). The sensor has a sensor input (1021), for sensing a signal forming a measure for the amount of electrical power presented at the sensor input (1021). The sensor input (1021) is electrically conducting connectable to an electrical path (14), along which electrical path (14) the modulated signal is transmitted. The detector (100) includes a filter (103) for removing from the sensed signal a part contributed to non-envelope signal components in the modulated signal; and a detector output (104) connected to the filter (103) for outputting an envelope signal.
