Develops a tunable duplexer that integrates power amplifiers, low noise amplifiers, and couplers into a single module, using self-interference cancellation techniques to dynamically adapt to multiple frequency bands. This reduces the component count in mobile radio front-end designs, minimizing PCB space, lowering manufacturing costs, and supporting the growing demand for higher data rates and more spectrum in devices like smartphones and wearables.

Problem
The increasing demand for data and more frequency bands in mobile devices leads to a higher component count of fixed-frequency filters in radio frequency (RF) front ends. This results in increased size, space, weight, and cost, posing significant challenges for original equipment manufacturers (OEMs).
Solution
Forefront RF offers a tunable duplexer that integrates power amplifiers, low noise amplifiers, and couplers into a single module, reducing the component count in mobile radio front-end designs. Utilizing self-interference cancellation techniques, the Foretune™ technology dynamically adapts to multiple frequency bands, simplifying RF front-end architectures and increasing performance and reliability. This integrated solution saves PCB space, supports more bands, and reduces manufacturing costs by mitigating the need for multiple product variants. The technology is designed to replace discrete components in traditional radio front-end modules with a smaller, integrated solution capable of supporting more bands.
Target Audience
The primary target audience includes OEMs of smartphones, smartwatches, and other mobile devices facing challenges related to size, space, weight, and cost in their RF front-end designs.
