D2D® Technology, also known as Direct-to-Data, revolutionizes RF communication by bypassing traditional methods for a more integrated solution. By converting RF signals directly to baseband data and vice versa, it optimizes the efficiency and performance of RF conversion processes. This technology excels in simplifying the transmission and reception of signals across numerous wireless applications, including mobile telephony, Wi-Fi, and Internet of Things (IoT). Protected by an extensive suite of global patents, ParkerVision's D2D® facilitates high-performance RF-to-IF conversion, minimizing power consumption and maximizing data throughput. With increasing demands for 4G and forthcoming 5G applications, D2D® stands out for providing robust solutions in managing high data rates and sustaining powerful signal integrity over wide frequency bands. This direct conversion method enables more compact, cost-effective RF environments, crucial for minimizing device size and power use. ParkerVision's D2D® Technology has significantly contributed to the evolution of wireless communication by making RF receivers far more efficient and effective. By enabling devices to process vast amounts of data rapidly and reliably, this innovation continues to shape the functionality and design of modern wireless devices, driving further technological advancements in RF integrated circuits and system-on-chip solutions.
Energy Sampling Technology represents a groundbreaking approach to RF receivers, focusing on direct-conversion methods. Historically, super-heterodyne technology dominated but proved inefficient for modern low-power CMOS applications. ParkerVision shifted paradigms with energy sampling, improving frequency down-conversion using a matched-filter correlator. This innovation enhances sensitivity, bandwidth, and dynamic range while minimizing RF signal division between I/Q paths. The resultant receivers boast reduced power consumption and enhanced accuracy in demodulation, making them highly suitable for compact CMOS implementations. This technology enables multimode receivers that adapt to shrinking CMOS geometries and supply voltages, fostering greater integration in devices. By streamlining design redundancies, the silicon footprint diminishes, and fewer external resonant structures are needed. This streamlined approach is not only cost-effective but also supports the evolving standards from GSM to LTE in various applications like smartphones, embedded modems, and tablets. Benefits including lower power usage, high sensitivity, and ease of integration make it a versatile solution across different wireless communication standards. With applications expanding into GSM, EDGE, CDMA, UMTS, and TD-CDMA, this technology supports energy-efficient RF receiver solutions, producing longer battery life and robust connectivity with less interference. It remains a vital aspect of producing compact, high-performance wireless communication devices suitable for the newest generation of smartphones.
