Innovative RF Front End

摘要

Just look at any recent smartphone or tablet, and it is a safe bet that it will be noticeably thinner than models of just a year ago. It is a trend that will continue. On the one hand, devices are getting thinner, and on the other hand, batteries, displays and functionalities are growing. The amount of space left for antennas, the device's connection to the network, decreases by 25 percent each year. In the past, mobile phones handled voice calls across two bands, and in some cases had Bluetooth®, GPS and Wi-Fi functionalities too. Today's devices have to cover 2G, 3G, 4G, Bluetooth, GPS and Wi-Fi plus large amounts of data while still supporting voice calls.
