Wideband RF Quadrature Modulator Targets Wireless Infrastructure
CML Microcircuits is targeting its new wideband RF I/Q modulator IC at the designers of, broadband wireless access systems (WiMAX), microwave link transmitters (including ODFM/COFDM), cellular picocell/nanocell systems, satellite communications and any other wideband wireless infrastructure systems requiring high performance I/Q modulation.
The Many additional features are included, such as gain control, uncommitted differential amplifiers, a digital control interface and an SPI compatible interface (for baseband devices of differing voltages). Advanced power management of individual internal blocks is also offered, giving optimum system performance under all conditions.
The CMX993W is available now, operates at 3.3V (1.8V I/O) and comes in a 48-pin VQFN package. For designers wishing to experiment with the product in their designs, an evaluation kit (EV9930) is available directly from CML.
