Q. What is the difference between a 3-port and a 4-port coupler? A. A directional coupler is basically a 4-port network. The main-line and auxiliary line each have 2 ports: a 3-port coupler has one end of this auxiliary line, the “isolated port,”...

The dual-double-balanced configuration of these FET mixers helps to improve dynamic range with reduced conversion loss and noise figure without expending DC bias. Recievers (Rxs) in support of the continually expanding wireless marketplace rely heavily on improved...

First, it’s important to define the significance of input levels. Then, details on the measurement technique will be given. Two-tone, third-order intermodulation distortion (IM) expresses the degree of non-linearity of an electronic device that has a definable...

RF transformers are widely used in low-power electronic circuits for impedance matching to achieve maximum power transfer, for voltage step-up or step-down, and for isolating DC from two circuits while maintaining ac continuity. They are also used for common mode...
