RF front end requirements for 3G and beyond

The cellular mobile terminals continue to evolve at a rapid pace from voice phones to Multi-band, Multi standard Multi-media devices of the future. The RF front end, of these devices continues to be more complex requiring many RF bands and Wireless standards to be supported in a single device. In addition, to support higher data rates multiple antennas and passive filters are required. Concurrency with other wireless standards puts additional constraints on passive filters, which are required to reduce the interference handling requirements of the RF transceiver. Innovation is needed in the components required in the RF front end such that the form factor, RF performance and power consumption is maintained to less complicated devices of the past, as more band and modes are added.
