Texas Instruments offers the TRF37A75EVM Evaluation Module, an easy-to-use, low-cost, and versatile RF evaluation and development platform for smart antenna applications. The package includes an integrated RF board and application software to accelerate the development process. The TRF37A75EVM is ideal for developers who want to evaluate, test, and prototype multi-antenna capabilities.

The RF board features a 50 Ohm matched input on the receive port and a 50 Ohm matched output on the transmit port. The board is composed of a TAS5624E, a 6 GHz 75 ohm quadrature low noise amplifier (LNA), a TRF37A75, an integrated 5-6 GHz 75 ohm low noise amplifier (LNA) with power detector and digital outputs, and a TAS5664EH, a 2 GHz 48 dBmm receiver chain front-end. The TRF37A75 also includes a wideband power detector with a wide dynamic range and two digital outputs. The TRF37A75EVM is capable of measuring up to 62 dBm without needing an external amplifier.

The board features integrated on-board shift registers, power control circuitry, dual voltage regulator for RF supply, bi-directional LVDS differential inputs, and I2C interface. The EVM can be powered by a single 5V/2A supply and utilizes a standard 50-ohm RF cable for transmit and receive connections. The board also allows monitoring and control of the LNA gain remotely over I2C.

The TRF37A75EVM supports both synchronous and asynchronous communications, allowing for direct measurement of total harmonic distortion (TDD) and adjacent channel leakage ratio (ACLR). The board also features auto-calibration stop of out-of-band emissions and can display an accurate total peak/average RF signal power output. This results in an accurate and consistent signal output power level and better overall signal fidelity.

The TRF37A75EVM is ideally suited for smart antenna applications due to its small form factor and ease of use. The EVM can be used in both multiband and single-frequency systems, allowing for more efficient antenna design and improved signal quality. The module can also be used in simultaneous transmit and receive applications with up to 8 antennas in 6 GHz applications. Developers can also operate the EVM with up to 16 independent antennas in various frequencies.

The application software included in the TRF37A75EVM makes development easier than ever. The software package includes a graphical user interface (GUI) for configuration, real-time data display, waveforms, and signal measurements. The software also features a scripting environment, allowing users to quickly and easily create custom scripts for their applications. The software can be used with a variety of development platforms, from desktop to embedded.

The TRF37A75EVM is the perfect solution for developers who need to evaluate, test, and prototype multi-antenna capabilities. The integrated RF board provides superior signal analysis capabilities, while the application software simplifies development and accelerates the process. With its small form factor and ease-of-use, the TRF37A75EVM is well-suited for smart antenna applications.
