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 ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...
