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 ...

Wide bandwidth radio transmitters commonly use analog quadrature modulators (AQMs) to convert complex (I + j*Q) baseband signals to radio frequencies (RF). An AQM consists of a local oscillator (LO) ...

PALO ALTO, Calif.--(BUSINESS WIRE)--GigOptix Inc. (OTCBB:GGOX), a leading provider of electronic engines for the optically connected digital world today announced successful results from collaborative ...

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 ...

Blame it on RF power amplifiers. Large and costly, they comprise roughly 40% of a basestation's cost. And since these amplifiers must transmit wide bandwidth signals of various modulation types, ...

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 ...
