RFMD has commenced high-volume production of multiple new power amplifiers (PAs) and power management integrated circuits (ICs) that incorporate RFMD's envelope tracking (ET) technology. RFMD's unique ET technology significantly enhances power efficiency in new LTE platforms, resulting in enhanced battery life across all modes and bands, increased network coverage, and higher data rate throughput.
Unlike traditional PAs that operate with a constant supply voltage, the supply voltage applied to RFMD's ET-enabled PAs is continuously adjusted so that the amplifier operates at maximum power efficiency. The result is much lower battery power consumption, particularly in LTE platforms.
RFMD's expanding ET product portfolio is tailored for 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's expanding portfolio of envelope tracking-enabled solutions includes its RF7389 and RF8085 multimode, multi-band PAs, the RF80xx(i) family of 10 single-band satellite PAs, and its RF8081 ET power management IC.
