RF Evaluation and development kits, boards, such as the NE664M04-EV04-A, are pieces of electrical equipment designed to evaluate an RF circuit\'s performance; they are effectively specialized test benches. The NE664M04-EV04-A is designed for the evaluation of the NE6640x transceiver range.

When evaluating an RF circuit, the main parameters used are gain, frequency, noise, signal-to-noise ration and power. Being able to accurately measure these will depend on the quality and precision of the test equipment used, which is why these development kits are so popular.

The NE664M04-EV04-A contains various components that are essential for establishing an RF system, such as an antenna, directional couplers, filter, amplifier, power detector and so on. These allow for a wide range of signal manipulation and testing as well as calibration. The device also contains an integrated controller to power off all of the components and take measurements, an LCD readout and a series of LEDs, which act as a signal\'s-strength indicator.

Using this kit for evaluation of the NE6640x range allows users to do so in a fast, accurate and repeatable manner. Connecting the test board to the transceivers enables the the user to analyse both receivers and transmitters simultaneously, allowing for detailed comparisons. This test board also supports various modulation types, which allows for a total and full understanding of the parts being tested without having a need for expensive and bulky vector network analysers (VNAs).

Using the NE664M04-EV04-A is simple and straightforward. Firstly, the user needs to connect the test board to the transceiver and power it on. The controller then powers off each component in a specific sequence, allowing the user to test each component individually and obtain the desired results. Once all the parameters have been measured, the results are displayed on the LCD readout and, depending on the user’s preference, can also be visualised in various forms of graph. This graph can then be used for comparison against other transceivers. The measurement process is then complete.

The NE664M04-EV04-A is a great accessory for evaluating the NE6640x transceiver range as it allows the user to quickly and 1easily measure the transceivers’ performance in both receivers and transmitters. Whether it be comparing parts to part, or getting graphs for analysis, the test board is a great help and allows for complete performance analysis.
