Simultaneously improve the linearity and efficiency of digital modulation transmitters! All circuits necessary for CFBL operation are built-in.
The CMX998 is an IC that incorporates all the circuits necessary for the operation of the Cartesian Feedback Loop (CFBL). It has the advantage of correcting the nonlinear distortion of the power amplifier (PA) to generate high-quality transmission signals, making it an effective product for improving the characteristics of digital transmission circuits. It can be directly connected to standard modem/interface ICs such as the CMX7163 (QAM data modem), CMX983 (analog front end "AFE" for digital radio), and CMX7364 (multi-mode high-performance modem) from CML Microcircuits. 【Features】 ■ Cartesian Feedback Loop IC ■ Generates high-quality transmission signals by correcting nonlinear distortion ■ Simultaneously improves the linearity and efficiency of the transmitter ■ Can be directly connected to wireless communication ICs CMX7163, CMX983, and CMX7364 *For more details, please refer to the related links or feel free to contact us.
