RF configurable power core covers multiband, multi-mode cellular air interface standards

PARIS — RFMD launched its PowerSmart power platforms, based on a new RF configurable power core for increased functional efficiency and delivering state-of-the-art processing for all known cellular communications modulation schemes.

The RF configurable power core at the heart of each PowerSmart platform incorporates all power amplification and RF power management functionality.

The PowerSmart platforms also include all necessary switching and signal conditioning functionality in a compact reference design, providing smartphone manufacturers a single scalable source for the entire cellular front end.

PowerSmart is modulation scheme agnostic and can support four bands of GSM/GPRS or EDGE and up to five bands of TD-SCDMA, WCDMA/HSPA+, LTE, WiMAX or CDMA – all within a product footprint that is 35 percent smaller than today's highest volume quad-band solutions, claims the manufacturer.

In a real-world comparison, versus today's highest volume triple-band 3G solution using power amplifier duplexer (PAD) modules, PowerSmart reduces board space requirements by greater than 40 percent according to RFMD.

By maximizing efficiency across power levels, across data rates (voice-only to LTE) and during non-ideal load conditions, the PowerSmart platforms also help to extend battery life and significantly reduce average thermal dissipation.
