What is RMS power detector?
What is RMS power detector?
BY contrast, RMS power detectors measure the average signal power of the input signal (RMS) as opposed to the amplitude or peak of the input signal. The DC output voltage of this detector is a representation of that average signal power. The response of this detector is linear-in-dB.
What is RF detector?
A radio frequency (RF) detector is a device used to detect the presence of RF waves either in a wireless or wired (on RF Cable) physical transmission medium. They are also known as RF power detectors or RF responding detectors and are available as devices or modules.
What is AD8302?
The AD8302 is a fully integrated system for measuring gain/loss and phase in numerous receive, transmit, and instrumentation applications. The ac-coupled input signals can range from –60 dBm to 0 dBm in a 50 Ω system, from low frequencies up to 2.7 GHz.
How does an RF diode work?
The positive half cycles of the input signal forward bias the Schottky diode, which in turn charges the capacitor. On the negative half cycle, the diode reverse biases, causing the voltage on the capacitor to be held and yielding a dc output that is proportional to the input signal.
How does envelope detector work?
An envelope detector (sometimes called a peak detector) is an electronic circuit that takes a (relatively) high-frequency amplitude modulated signal as input and provides an output, which is the demodulated envelope of the original signal.
What is a log detector?
Logarithmic Detectors are particularly suited to perform high dynamic range power measurements and are used in a wide range of automatic gain control and pulse detection applications. These devices produce a low frequency (DC) output that is logarithmically (“linear in dB”) related to the input signal level.
How does a RF signal detector work?
An RF detector monitors or samples the output of an RF circuit and develops a dc output voltage proportional to the power at that point. RF power, rather than voltage, is the primary measure of a wireless signal. In a receiver, signal strength is a key factor in maintaining reliable communications.
What is the function of phase detector?
A phase detector is a mixer-like circuit that puts out a signal that is proportional to the phase difference between two input signals of the same frequency.
What are PIN diodes used for?
PIN diodes, which sandwich a lightly doped intrinsic (I) region between heavily doped P and N regions, are used extensively in RF and microwave applications. Common applications of PIN diodes are microwave switches, phase shifters, and attenuators, where high isolation and low loss are required.
