Consumer Microcircuits Limited CMX971
The CMX971 is a high performance quadrature modulator featuring a wide operating frequency range and attractive power consumption. The small, RF-optimised VQFN package and minimal external components make the device ideal for spaceconstrained applications. Control of the CMX971 may be either by serial bus or by direct control (with reduced functionality).FEATURES
