RFMD has announced that the newest flagship Android smartphone incorporates its envelope tracking (ET) power amplifiers, antenna switch module, diversity switches and antenna tuner. This fifth generation smartphone from a leading Korea-based manufacturer is the slimmest and fastest Android phone to date and the first new smartphone to benefit from the improved power efficiency of RFMD's ET power amplifiers (PAs) and antenna control solutions.
This Android 4.4- (KitKat-) equipped smartphone integrates RFMD's RF8017 and RF8020 ET power amplifier modules; RF1492A antenna switch module; RF1119 antenna tuners; RF1136, RF1633 and RF1660 diversity switches; and RF5521 low-band Wi-Fi and RF5540 high-band Wi-Fi switch LNAs. RFMD's ET PAs are designed to maximize the efficiency of the phone's quad-core processor while RFMD's antenna control solutions help optimize antenna efficiency.
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. RFMD is a pioneer in the development of RF power management and envelope tracking technology. 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 up to 25% less current consumption which translates to much lower battery power consumption, particularly in LTE platforms.
