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 ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...
