NXP Semiconductors RF-IF Solutions

NXP Semiconductors RF-IF Solutions meet the needs of the most demanding RF applications by allowing designers to meet the highest specifications for performance while still retaining potential trade-offs with respect to efficiency, power, ruggedness, consistency, and integration levels. The NXP RF-IF portfolio covers the majority of communication and transmission systems, making it easy to find a solution that matches a designer's particular requirements. NXP RF-IF solutions include the SA6xx Series RF/IF building blocks that are ideal for a variety of niche handheld RF products. Available in small-footprint packages, SA6xx solutions save PCB space while providing better RF performance.
