RFMD's envelope tracking enables 4G smartphones
RFMD has come up with multiple upcoming reference designs for 4G smartphones which will feature the company's envelope tracking (ET) power amplifiers (PAs) and power management integrated circuits (PMICs).
RFMD says its ET RF solutions enable next-generation 4G smartphones and tablets to achieve significantly enhanced power efficiency, resulting in enhanced battery life across modes and bands, increased network coverage, and higher data throughput.
The upcoming 4G baseband reference designs featuring RFMD's ET-capable RF solutions will support global multimode, multi-band coverage and feature advanced multi-core processing capabilities. The upcoming 4G smartphones will incorporate multiple RFMD ET-capable RF solutions, including MMMB and discrete satellite PAs and ET PMICs.
RFMD estimates its ET-capable RF solutions will support the leading ET-capable LTE devices scheduled to ramp in 2014. As an example, in an upcoming ET-capable flagship Android smartphone, RFMD's content will include RFMD's ET MMMB PA (covering bands 1-5, 8, 18 and 26), three ET satellite PAs (for bands 7, 17 and 20), a PA module for TD-LTE (band 41) and 3G/4G antenna diversity switches.
"RFMD is uniquely positioned to expand our content in the world's leading 4G devices throughout 2014, as major new programs are introduced and ramp to volume production," says Eric Creviston, president of RFMD's Cellular Products Group."By combining our deep systems-level expertise with the breadth of our PA product portfolio and our leadership in RF power management, cellular switching, and antenna control, we are designing, manufacturing and delivering the broadest portfolio of scalable, end-to-end RF solutions, and we are helping the world's leading smartphone manufacturers to progress quickly and efficiently from design and layout through to mass production."
