Product Description
RFMD's RFRD6461 3G multi-band, multimode PowerSmart™ power platform is targeted at
smartphones and mobile internet devices (MIDs) by providing extensive flexibility and custom-
ization, "user experience" focused performance with real-time battery life optimization, and a
dramatically smaller front end solution size-all while accelerating an original equipment manu-
facturer's (OEM's) time to market.
At the heart of the RFRD6461 is the industry's first RF configurable power platform, designed to
seamlessly merge RFMD's leading, industry-proven VSWR-tolerant, quadrature power amplifier
technology with RFMD's patented power management technology in a new category of cellular
sub-system. Although comprised of two separate component placements, the RF6261B (or one
of its tri-band or dual-band derivatives - see RF6261B data sheet for these variants) and the
RF6561, these components were developed to operate seamlessly as an agile and highly RF
configurable power platform. The RF configurable power platform enables up to 5 bands of
WCDMA/HSPA+ operation, and provides performance and battery life customization without
hardware changes as well as the ability to maximize efficiency across power levels, data rates,
and during non-ideal load conditions (VSWR).
