Here’s a crude (but simple to implement) complex signal envelope detection scheme. By envelope detection, we mean estimating the instantaneous magnitude of a complex signal x c (n). Whether this ...

Envelope tracking technology optimises the efficiency of radio frequency (RF) power amplifiers by dynamically adjusting the supply voltage in accordance with the amplitude envelope of the input signal ...

To address the challenge of improving power-added efficiency (PAE) for high-powered amplifiers, Analog Devices developed the ADL5511 TruPwr rms and envelope detector. The chip combines two RF ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

Abstract: Chromatic Dispersion (CD) of Standard Single-Mode Fibers (SSMF) is generating a characteristic phase perturbation of propagating pulses, even before these pulses are substantially broadened ...

Abstract: This research first presents a hybrid quadrature polar modulator to drive the power amplifier (PA) highly efficiently in a wireless RF transmitter required for multi-mode operation. The ...
