Designers of wireless base stations need practical tools that shorten the development time and deployment of next-generation wireless systems. Optichron's Digital Pre-Distortion (DPD) Development Tool Suite offers complete signal compression and transmit path linearization from baseband processor to power amplifier (PA) in easy-to-use, GUI-driven solutions. Our DPD Development Platforms include development board hardware solutions that can be used as evaluation tools, development vehicles and as reference designs for multiple product designs. Development boards are supported by a comprehensive GUI and documentation including schematics and Gerber files, and require minimal instrumentation for use. In addition, a USB debug adapter directly connects the GUI with our DPD Development Platforms and customer hardware.

DPD Development Platforms for OP6180 DPD Family
Our DPD Development Platforms meet the most critical needs of the system designer - versatility, performance and ease of use. These complete and flexible development tools provide a foundation for evaluating and developing multiple, highly-efficient, product designs that support various protocols and frequency bands. The universal DPD algorithm in the OP6180 eliminates any need for algorithm software development and subsequent software maintenance. In addition to the Optichron DPD and CFR functionality in the OP6180, the development boards contain all of the necessary components for a complete transmit loop, with the exception of the customer's selected driver and power amplifier (PA).

DPD Development Platforms for OP4400 DPD Family
Our DPD Development Platforms meet the most critical needs of the system designer - versatility, performance and ease of use. These complete and flexible development tools provide a foundation for evaluating and developing multiple, highly-efficient, product designs that support various protocols and frequency bands. The universal DPD algorithm in the OP4400 eliminates any need for algorithm software development and subsequent software maintenance. In addition to the Optichron DPD (OP4400) and CFR (OP5000) functionality, the development boards contain all of the necessary components for a complete transmit loop, with the exception of the customer's selected driver and power amplifier (PA).

GUI (Graphical User Interface)
A key benefit of the DPD Development Tool Suite is ease of system evaluation, development, implementation, manufacturing and QA. Each development system and USB Debug Adaptor is delivered with a GUI which provides the interface to Platforms and debug adaptors. The easy-to-use Optichron GUI is comprehensive yet simple, enabling the flexible configuration of design features. It runs on a laptop PC and supports seamless migration from evaluation through development to the production vehicle and field service with the USB debug adapter.

USB Debug Adapter
The USB debug adapter is a small board that provides direct communication to customer hardware from the same GUI that is used to evaluate and develop solutions for CFR and DPD using the DPD Development Platform. This provides full control over all operational aspects of the DPD and CFR in the customer system. This tool may be used to program the serial Flash PROM that initializes both devices. Flash images may be downloaded to the customer system and direct access to the DPD/CFR functionality are delivered via the GUI. The USB debug adapter is also a solution for the telecommunication industry's manufacturing and provides direct insights into the operation of the transmit path using Optichron DPD/CFR solutions. Transmitters may be tuned and QA'd with this tool as well as serviced in the field.
