CML Microcircuits unveiled a new I/Q modulator in its family of RF integrated circuits. The CMX993 is a highly integrated, general-purpose RF quadrature modulator that operates between 100 MHz to 1 ...

Which RF modulators are best? RF modulators can help to connect old-school technology in an era where many classic devices are being forgotten. VHS players and older gaming consoles are increasingly ...

The circuit presented here makes amplitude modulation possible, and it also has the significant advantage that it replaces the somewhat exotic and quite expensive OP603AP output opamp with a standard ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...
