AD8349-EVALZ Application Field

The AD8349-EVALZ board is designed for applications such as wireless communication systems, instrumentation systems, satellite systems, aerospace, automotive, and military applications. With its adjustable gain control, it is suitable for testing the performance of power amplifiers, input/output matching circuits, signal lines, and input/output isolators. It gives engineers the ability to measure DC parameters like the gain, stability, and bias current. It is also used to measure AC parameters such as frequency response, gain flatness, and harmonic distortion.

AD8349-EVALZ Working Principle

The working principle of the AD8349-EVALZ board is conceptually simple. The board consists of two power amplifiers, adjustable gain circuitry, and an input/output matching circuit. The two power amplifiers provide an output of approximately 50W to drive a device under test (DUT). The adjustable gain circuitry is responsible for providing a different gain factor for the power amplifiers, and for controlling the power output of the DUT. A low pass filter is also provided to the output of the DUT, which helps reduce unwanted harmonic distortion. Furthermore, the input/output matching circuit allows the DUT’s input and output signals to match the board’s input and output impedances.

Conclusion

In conclusion, the AD8349-EVALZ board is a powerful tool for engineers to use in the design of RF devices. It consists of two power amplifiers, adjustable gain circuitry, and an input/output matching circuit. This board is well-suited for a wide range of applications, such as wireless communication systems, instrumentation systems, satellite systems, aerospace, automotive, and military projects. Additionally, the adjustable gain control allows engineers to test the performance of power amplifiers, input/output matching circuits, signal lines, and input/output isolators. Moreover, other parameters such as gain, stability, frequency, response, gain flatness, and harmonic distortion can also be assessed with the AD8349-EVALZ. In this way, the board gives engineers a great amount of control over the design of RF devices.
