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 ...

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, ...

TM Technologies, a division of Medusa Scientific, announced this week that it has successfully demonstrated a “breakthrough modulation technology” that has the potential to increase data rates between ...

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 ...
