A RF evaluation and development kit is a powerful tool that helps to increase the understanding and functionality of electronic systems used to support product development. The SKY85309-11EK1 from Skyworks is one such kit available to development engineers. It can be used to evaluate the performance of the SKY85309-11 single-stage amplifier stage in a variety of applications in communication systems. The evaluation board includes a presentation of the performance of the SKY85309-11 in typical applications along with the associated test results.

The SKY85309-11 is a single-stage amplifier designed specifically for use in both wireless and satellite communication systems. It is suitable for applications including cellular, GPS, Wi-Fi/WiMAX, and Bluetooth. It also offers exceptional linearity and thermal stability across a wide temperature range, making it an ideal choice for high-performance applications. The amplifier can be powered from 2.5V to 3.3V and is characterized with a gain of 16dB and P1dB of 19.3dBm.

The SKY85309-11EK1 RF Evaluation Kit provides an ideal platform for making testing and troubleshooting of the amplifier quick and easy. It is supplied with two SMA connectors, one to be connected to the input signal and the other to the output of the amplifier. The kit includes a number of evaluation boards and accessories including the evaluation board, a test stand, coaxial cables, a terminal block, and a jumper wire. Additionally, the test stand allows for the quick and easy assembly or disassembly of the RF components.

The working principle of the SKY85309-11EK1 evaluation board is based on the design of the internal amplifier stages of the SKY85309-11 amplifier. The board features a single-stage amplifier and a low-noise amplifier (LNA) connected in series to provide a gain of 6 dB between the input and the output. The amplifier includes a power gain control with a range of 0-127. The control signal can be applied to the board via solder jumpers located on the terminal block included in the test stand. Furthermore, the board provides a DC bias of 2.5-3.3V to the signal chain.

The SKY85309-11EK1evaluation board makes use of an integrated slot-type isolation switch which can be used to break up an application circuit into different elements and visualize their individual behavior. This allows for detailed characterization of the amplifier such as input/output matching, linearity performance, harmonics, impedance, gain ripple, and noise. Additionally, the board allows the designer to quickly test the functionality of amplifier stages individually to help identify any areas of concern.

The SKY85309-11EK1 evaluation board is ideal for assessing the performance of the SKY85309-11 amplifier for a variety of applications. It is suitable for use in a variety of product development roles such as evaluation of the performance of amplifier stages for wireless and satellite communication systems. Additionally, the evaluation board can be used to quickly identify any potential issues with the amplifier design or implementation, as well as to test different amplifier configurations.
