Low power multi-protocol wireless Wi-Fi SoC targets IoT
The Talaria TWO multi-protocol wireless platform from fabless semiconductor company InnoPhase is a highly integrated, SoC offering the ultimate size, power and cost advantages for a wide range of low-power, battery-based IoT product designs such as security cameras, smart doorbells and monitoring devices.

The technology – PolaRFusion

InnoPhase was founded on the premise of creating a totally new, extremely efficient and digitally-dominant radio architecture that would finally enable wireless systems to take full advantage of the significant low power, size, integration and cost advantages that advanced semiconductor process technology bring to the market. To this end, the company has succeeded in moving semiconductor radio signal processing from a predominantly power-hungry analog solution into highly efficient, extremely low power digital circuits.

InnoPhase has coined the term “PolaRFusion” to describe this major advance in the way RF signals are processed in the radio. The key InnoPhase differentiator is how the RF waveform is encoded and decoded using polar coordinates, amplitude and phase, in place of traditional Cartesian/IQ coordinates, in-phase and quadrature, that are used in traditional analog-based radios.

To maximize energy efficiency, InnoPhase has developed a purpose-built, low power “polar coordinate processing” architecture with an optimized instruction set based on advanced nonlinear mathematics for manipulating these now digitally-represented polar coordinates. In addition, as the radio signal travels through the PolaRFusion transceiver it can now be accurately processed using software algorithms. Entire portions of the radio hardware that used to be dominated by analog processing have been moved into digital circuits. The unique and patented flexLNA (flexible low noise amplifier) and DPA (digital power amplifier) are also implemented in digital CMOS circuits and major portions of the RF signal is processed using flexible, programmable software algorithms.

Overall radio power reductions associated with using the digital PolaRFusion architecture are startling. For example, compared to the lowest power Wi-Fi wireless IQ architecture solutions in use in the market today, batteries in low power IoT applications last 2X to 8X longer. InnoPhase designed radios using the PolaRFusion architecture drastically reduces analog circuit power consumption by up to 65% compared to the lowest power IQ radios in use in the market today.
