RF evaluation and development kits, boards have evolved from simple stand-alone pieces of equipment to be incredibly configurable, complex components of the larger system. Applications in test and measurement, commercial telecommunications, data storage, military applications, and medical imaging rely on these evolutions to monitor, analyze, and control systems. A example of such a board is EV1HMC642ALC5. This paper explains the application field and working principle of EV1HMC642ALC5.

The EV1HMC642ALC5 is a high-performance, low-power evaluation board used to measure and characterize antennas in various frequency ranges. It consists of the EV1HMC642ALC5 antenna tuner evaluation board, as well as the associated Radio Frequency Evaluation Kit (REF-EVK) and noise source (NS-EVK). The EV1HMC642ALC5 antenna tuner board combines a high-speed, 24-bit analog-to-digital micro-converter (ADM) with a low-power, embedded field-programmable gate array (FPGA) and two 14-bit digital-to-analog converters (DACs). It supports the connection of multiple antennas to a single, integrated broadband tuner, enabling the measurement of multiple frequencies across a range of frequencies. This provides an unprecedented level of accuracy, making it ideal for applications requiring precise measurements and characterization.

The EV1HMC642ALC5 board can be used for a wide range of applications. It is designed to enable users to evaluate antennas for various military and commercial applications, requiring a typically congested and challenging environment. It allows fast measurements of RF coverage and quality of communication, which are essential for optimization and validation of mobile device performance. This device can also be used for evaluation of distributed antenna systems (DAS) for an indoor or outdoor coverage areas as well as monitoring of antennas operating in a wide range of frequency bands for both macro-cellular and small-cellular applications.

EV1HMC642ALC5 board features an Open Loop mode, which can be used to measure the absolute field strength and return loss of antennas connected to the board, and a Closed Loop mode where the tuner can be used to measure antennas in a wide variety of scenarios. Optional software can be used to evaluate antennas in more detail, including the return loss, phase, absolute field strength, efficiency, and far field radiation patterns of antennas connected to the board. Furthermore, evaluation of antennas in different modes, such as linear, circular, and elliptical polarization, is also supported.

The EV1HMC642ALC5 board supports antennas in the range of 400 MHz to 6 GHz, typically used in a variety of applications such as wireless telemetry, point-to-point, and line-of-sight communication systems. Besides a broad frequency range, this board is also equipped with a high speed hardware controller, which allows it to process large streams of RF data quickly and in real-time. The board also offers a wide range of feature tuning options, such as gain control, antenna modes, and more.

In conclusion, the EV1HMC642ALC5 board is an excellent solution for testing, evaluating, and optimizing antennas in the 400 MHz-6 GHz range. Thanks to its high-speed ADC and embedded FPGA, excellent results can be achieved via a broad range of measurement setups: both Open Loop and Closed Loop modes are supported by the board. It also enables users to monitor RF coverage and quality of communication in challenging and congested environments. The board may find applications in both commercial telecommunications and military applications.
