RF evaluation and development kits, boards, such as TXR1222EVM, provide a working platform for designers to understand the functionality and operation of RF circuits where the behaviour and performance can be observed and verified. Such products most often contain analog and digital signal processing components to enable the study and evaluation of radio frequency technology and the exploration of a wide range of operational characteristics.

The TRF1222EVM-board from Texas Instruments is a U.S. Cellular 3GPP Release 8 compliant, end-to-end (E2E) test system for assessing the link performance of a radio provided by a base station. The device includes an evaluation module board (EVM), and is designed to receive or transmit digital data streams at multiple rates while testing a base station or any wireless device. The E2E platform is performance-verified to ensure that all connections, communications, and interactions between the base station and wireless device work properly.

The TRF1222EVM also includes options that allow a user to manage the consistency of the device’s performance when operated in different environments. The evaluation board is equipped with a temperature range controller, allowing the user to measure the radio frequency device’s performance at various temperatures, while the power-supply lines on the board eliminates the need to use external voltage sources for testing. Additionally, TRF1222EVM offers a number of control options to help engineers evaluate the performance of radio frequency devices, such as a frequency-tuned subcarrier, fading simulator, voltage-controlled oscillator, and a full-range gain controller.

The working principle of the TRF1222EVM is implemented by its internal components, which include a digital signal processor (DSP) core and an integrated radio frequency-specific analog front end. The processor provides the necessary processing, while the front end is responsible for converting analog signals for use with the processor, and converting digital signals received from the processor into the analog signals necessary for radio transmission. Together, these components are used to perform the required functions on the radio frequency interface.

The EVM also contains a variety of RF components to enable building of a test system. The RF components include a dual-band frequency synthesizer, a receiver-transmitter (RX-TX) switch, a low-noise amplifier (LNA), a receiver amplifier (AMP), a power amplifier (PA), a protection/matching filter, and a transmitter matching/biasing network. Thus, the EVM provides engineers with all the necessary components needed to evaluate the performance of their base stations or other wireless devices.

Other features of the board include a low-distortion quadrature detector, a direct conversion receiver, a transmit modulator, and a high-bandwidth composite selection circuit that helps to filter out interference. The board also features a signal power measurement module, which measures the amount of power received from the radio frequency device being tested. Finally, TRF1222EVM features a signal-in-noise measurement module, which measures the signal-to-noise ratio of the radio frequency device.

In summary, the TRF1222EVM from Texas Instruments is a versatile and efficient testing platform for evaluating the performance of base stations and other wireless devices. It contains a variety of components needed to build a test system, and its various features enable engineers to accurately evaluate the performance of their device in a variety of different environments. The internal components of the EVM enable the device to perform the required functions on the radio frequency interface and ensure that all connections, communications, and interactions between the base station and the wireless device work properly. The EVM is the perfect testing platform for testing and verifying the performance of a wireless device.
