The CMX979 from CML Microcircuits is a low power dual RF/IF synthesiser + VCO that provide signal generation over a wide range of frequencies. The RF synthesiser operates over the range of 2.7 - 3.6 GHz with a fully-integrated VCO and PLL and is capable of operating in frequencies in the range of 338 MHz to 3.6 GHz via a configurable output frequency divider.
The CMX979 provides the designer a solution to develop smaller and lower powered RF solutions due to the highly integrated nature of the product. It directly supports both single conversion and super-heterodyne radio architectures and minimises the number of external components needed. Most other integrated solutions are only single synthesisers and so require a second synthesiser to be placed on the PCB in many applications. This device can be used in satellite modems, CATV Equipment, ISM Band modems and a number of other applications.
