Key operators in China and South East Asia have a focused set of spectrum allocations for 5G but require the most 4G/5G dual-access (EN-DC) use cases, all of which can be supported in Skyworks’ Sky5® award winning low-power, high-performance radio front-end products. A set of highly integrated modules that support all required bands and combinations is shown in the block diagram example below.
