CMX971 – RF Quadrature Modulator
The CMX971 is a high performance RF 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.
Devices are available through our Distributor Network.
