QAM Modulator & Demodulator

"The modulation and demodulation of quadrature amplitude modulation, QAM utilises circuits that are able to accommodate both I and Q components. In any system that uses quadrature amplitude modulation, QAM, there will be modulators and demodulators. Th

Tips on Antenna Gain Measurement

"Gain is one of the most common measurements stated on antenna specification sheets. But you shouldn't judge an antenna by gain alone, especially if you're unclear on its true meaning. "Gain” and “decibel” have certain meanings when referring t

Things You Should Know About Antenna Gains

" The term Antenna Gain describes how much power is transmitted in the direction of peak radiation to that of an isotropic source. ----- FMUSER" On this page, we'll introduce another fundamental antenna parameter

Understanding Antenna Gain Basics

"Antenna gain indicates how strong a signal an antenna can send or receive in a specified direction. Gain is calculated by comparing the measured power transmitted or received by the antenna in a specific direction to the power transmitted or received by a hy

dB and dBi and Antenna: What does Antenna Gain Actually Means?

"Choosing the right signal booster and supporting antenna with sufficient power gain to boost your cellular signal is the key. There are many things to consider and here we are going to discuss dB, dBi and gain and what all these mean to signal boosters. ----

Basic Antenna Theory: dBi, dB, dBm dB(mW)

"The terms dB, dBM and dBi are often used interchangeably and hence incorrectly because they each mean different things (although from the context it's often obvious what someone means). There's no such thing as a "5dB aerial", for
