Technical Summary

Horizon Analog offers innovative solutions in nonlinear noise reduction for wireless and wired communications

Horizon Analog has innovative nonlinear interference reduction technologies for wireless and wired communications. These solutions can be employed alone or in addition to any other noise reduction means to significantly improve the performance of telecommunications, power, and audio devices. Mitigating such interference is increasingly critical for devices with a high density of digital circuits and multiple transmitters and receivers, such as smartphones.
