RF Evaluation and Development Kits, Boards

SKY13370-374LF-EVB is an evaluation board designed by Skyworks Solutions, Inc. for use in evaluating its discrete power amplifiers within a given application. The evaluation board facilitates the evaluation of the power amplifier by allowing the designer to easily adjust operational parameters, monitor core characteristics and switch different features. The evaluation board provides an easy-to-use platform for quickly evaluating power amplifier performance in different configurations and helps designers more quickly move from concept to prototype.

The SKY13370-374LF-EVB has five amplifiers on board and is powered by an external DC power supply. Data are provided via an RS232 connection. The board supports full duplex transmission with data rates up to 2.5 Mb/s. The backplane includes a high power amplifier, a directional coupler, a digital tuner, three separate RF ports, a bias controller, and a high frequency mixer.

Application Field

The SKY13370-374LF-EVB is designed primarily for wireless, military and aerospace applications. Its primary purpose is to enable evaluation of power amplifiers by providing designers with a complete environment for evaluating the power amplifier in different configurations. The board supports applications such as satellite communications, GPS, cellular communications, Wi-Fi, WiMAX, and ZigBee, allowing designers to easily evaluate power amplifier performance in these different technologies.

The board contains several features that can be used to customize the board for specific applications. For example, the board contains a digital tuner, which can be used to configure the gain level of the device, as well as a bias controller, which can be used to adjust the bias current. Additionally, the board includes switches to enable designers to route signals through the on-board directional coupler or through connecting external components. This allows for the use of the board to evaluate different control and feedback loops.

Working Principle

The SKY13370-374LF-EVB is designed to operate in a particular environment. As a general rule, the evaluation board should be located in either an open or a shielded space. The shielded space should be well ventilated to avoid any possible overheating or damage to the components upon use. Additionally, all external connections should be made with low-power equipment to ensure protection of the board from any potential static discharge.

Once the board is placed in the desired environment, the designer must configure a set of parameters, such as desired gain, bias current, and forward/reverse isolation. These parameters are adjusted through the use of either the on-board digital tuner or via the use of external components. Once configured, the board\'s performance can be monitored via the RS232 port or more closely monitored through the on-board directional coupler.

Once the parameters have been set and the performance has been monitored, the designer can then begin the evaluation of the power amplifier performance within the given application. This includes evaluating the total power output, gain, and linearity of the power amplifier under a given set of conditions. Once the evaluation has been completed, the designer can then use the data generated to determine if any adjustments need to be made to the board to optimize its performance within the given application.

Overall, the SKY13370-374LF-EVB is an easy-to-use evaluation board designed to provide designers with a platform for quickly evaluating power amplifier performance in different configurations. The board\'s capabilities allow designers to develop devices that are cost effective and perform optimally in the desired application.
