RF Micro Devices Inc., a global leader in the design and manufacture of high-performance radio frequency solutions, announced the addition of multiple new products to RFMD's industry-leading portfolio of envelope tracking (ET) power management and power amplifier (PA) solutions. RFMD's ET-based solutions leverage the company's leadership in RF power management and cellular PAs to improve system-level efficiency in high-data rate applications.

The new RF solutions — the RF7389, RF7390, RF7459, RF8081, and RF8085 — comprise ET PMICs, ET multimode multi-band (MMMB) PAs, and ET ultra-high efficiency PAs. RFMD's expanding ET product portfolio is compatible with the leading LTE chipsets and provides full ET compatible coverage of all FD-LTE and TD-LTE bands (1-14, 17-21, 25-28, 38, 40, 41, and 44).

RFMD anticipates the combination of ET technology and RFMD's advancements in RF power management will be a disruptive combination that raises the bar significantly in RF performance. RFMD is a pioneer in RF power management and has shipped tens of millions of power management integrated circuits (PMICs). RFMD is also a leader in RF power control and has shipped hundreds of millions of power amplifiers (PAs) with integrated power control.

Eric Creviston, president of RFMD's cellular products group, said, "RFMD is at the forefront of technology development in RF power management, and we are enthusiastic about the deployment of ET-based solutions. We believe the importance of power management technologies such as average power tracking (APT) and envelope tracking will continue to expand in smartphones, enabling RFMD to leverage our combined leadership in power amplifiers and RF power management and increase our RF content opportunity."
