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 ...
Crystal radios used to be the “gateway drug” into hobby electronics. Trouble was, there’s only so much one can hope to accomplish with a wire-wrapped oatmeal carton, a safety-pin, and a razor blade.
Simplifying envelope extraction of high peak-to-average modulated signals in wireless, instrumentation, military, and broadband applications, the ADL5511 TruPwr rms and envelope detector improves ...
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 ...
