Such a circuit includes a rectifying diode, filter capacitor, resistor, and possibly an RF choke and a second capacitor. The two simplest detector circuits are half-wave rectifiers.

The LMV221 RF power detector from National Semiconductor Corp., Santa Clara, Calif., targets mobile-phone power controls in current and emerging cellular standards, including ...

Abstract: This paper describes the design and implementation of a low-power wide dynamic range radio-frequency (RF) power detector in a standard 0.18-μm CMOS process. The proposed circuit includes a ...

Analog Devices has its first dual-channel radio frequency root-mean-square (rms) power detector for precision measurement of transmit and receive signals up to 2.7GHz. The AD8364 is designed to ...

Avalanche-photodiodes (APDs) as photosensors in positron emission tomography (PET) detectors have been extensively investigated in this field. Compared with conventional photosensors such as the ...
