Product description

The CMX971 is a high performance quadrature modulator featuring a wide operating frequency range and attractive power consumption.

Control of the CMX971 can be by serial bus or by direct control (with reduced functionality).

The small, RF-optimised VQFN package and minimal external components make the device ideal for space-constrained applications.

The CMX971’s quadrature architecture supports a wide range of modulation formats and standards. The device provides translation from baseband I/Q signals to a modulated RF signal.

The differential inputs are ideal for direct connection to standard modems and interface ICs such as CML’s CMX7163, CMX7164, CMX910, CMX981 and CMX7861.
