RF Evaluation and Development Kits, Boards

The SI4212-TKDX-EVB is a RF evaluation and development (E&D) kit, board, aimed at enabling designers to quickly prototype their designs and uncover design issues. This device is well suited to a range of applications in the wireless communication field, particularly those where high power and frequency tuning add value.

Application Field

The SI4212-TKDX-EVB is designed primarily for use in the development of high-power, high-frequency, radio-frequency (RF) applications such as mobile base stations, wireless microphones, automotive systems, and wireless backhaul systems. It is also suitable for use as an automated test instrument in the production environment to detect short-term manufacturing defects. The RF signal generator module comprises a high-frequency switching device, allowing both receive and transmit applications to be realized, and enabling precise measurements to be performed. Additionally, the board provides interchangeable RF inputs, allowing different frequencies to be used.

Working Principle

The board is designed and built to minimize parasitics and reduce the effects of signal loss. The modular architecture of the board enables a number of components to be swapped to allow maximum flexibility for the desired application. It operates on the principle of RF transceiver use: Thermal noise can cover up any crosstalk at the receive frequencies, and it’s possible to have multiple channels operating at the same time, combining the low power signals from each. The transmit power and gain are adjustable via an adjustable bias, and this board also offers adjustable TX/RX isolation ability as well as a metered output.

The board utilizes an on-board Synthesizer to control the frequency of operation. It is adjustable over a wide range of frequencies and can be tuned to arbitrarily adjust the oscillation frequency of the external LNA filter that is used to shape the received signal. This allows the user to easily adjust the board to be optimized for the particular application.

Conclusion

The SI4212-TKDX-EVB is an ideal solution for anyone looking to quickly prototype or test high-power RF designs. Its modular design enables maximum flexibility for the desired application and its adjustable frequency range allows users to easily adjust the board to optimize their design. Its wide range of use cases includes mobile base stations, wireless microphones, automotive systems, and wireless backhaul systems, as well as automated test instruments in production environments.
