AN26072A-EVB-0 Application Field and Working Principle

AN26072A-EVB-0, also known as RF Evaluation and Development Kits, is a type of system used for operations, testing and tuning of Radio Frequency or RF designs. The board provides designs with three selectable output frequency bands –900 MHz, 1800 MHz and 2600 MHz– that is suitable to cover various cellular communication standards like GSM, W-CDMA, LTE, etc.

The AN26072A-EVB-0 commonly consists of a number of components such as a direct digital synthesis core, an upconverter, a programmable attenuator and a transmit power amplifier. The synthesizer core of the system is powered by a direct digital synthesis technology; it sets up a proper frequency plan for the DDS along with a programmable divider; FPGA is used for the development of the phase- locked loop (PLL) due to its highly programmable nature.

The synthesized output of the core is then sent to the upconverter module, here through a mixer nonlinear process, the output frequency is shifted up by an offset frequency. The output of the upconverter is then transferred to the power amplifier where the power output is boosted to a higher level.

Due to the convenience of the solution, the AN26072A-EVB-0 can be used in a range of scenarios. For example, they can be utilized in Smart Metering applications as they ensure a proper functioning of the Radio Frequency unit, as well as for BLE, wifi, Zigbee or other applications, making it easier to comply with the relative RF standards.

Additionally, due to the design of the system, the AN26072A-EVB-0 can be used in research and development in order to assess the capacity of the system either for new applications or for further development of existing ones. For example, a scientist may be interested in using the system for distortion calibration and tuning of their designs.

The AN26072A-EVB-0 can be used to easily and efficiently tune parameters such as power output, phase-lock loop, and power amplifier linearity, making it an attractive choice for RF designers and scientists.

In conclusion, the AN26072A-EVB-0 is a very useful and versatile RF evaluation and development kit that is ideal for research and development, as well as for use in various applications. Through its built in components it ensures that radio frequencies are used efficiently and effectively, allowing designers and scientists to further build and refine their designs and come closer to their desired outcomes.
