RF evaluation and development kits, boards can provide a fully-integrated hardware platform and environment for the development, testing and optimization of radio frequency solutions, helping shorten development time and reduce validation cost. As one of a versatile range of evaluation boards, ADA2200-EVALZ delivers fully integrated circuit functionality and consists of two boards that are directly connected. This article will discuss its application field and working principle.

Application Field

ADA2200-EVALZ is suitable for a wide range of applications that require high linearity and low noise, such as RF signal generators, receivers and transceivers in wireless communication systems. As an example, the ADA2200 evaluation board can be used to develop high-performance, fully-integrated RF transceivers for WLAN, Bluetooth and wireless local area network (WLAN) applications.

Working Principle

ADA2200-EVALZ consists of two evaluation boards, making it easy to customize and test the performance of different RF transceiver components, such as LNAs, mixers and up/down converters. The many adjustable parameters (including supply voltage, frequency, bias, gain, etc.) of the different components can be adjusted within the two boards, and the total performance of the combination measured.

The two boards work together to help develop complete RF transceiver solutions. The ADA2200-1 board accommodates the IF and RF stages of the transceiver, while the ADA2200-2 board houses the necessary components such as phase-locked loops (PLLs), frequency synthesizers, digital signal processors (DSPs) and other digital blocks. The two boards are interconnected through the Sub-Miniature-A (SMA) connectors, providing flexible and comprehensive signal interchange between RF and digital blocks.

The ADA2200-EVALZ also has an USB3.0 and USB2.0 interface, allowing easy connection to the host PC for program control, real-time data acquisition, and other functional tests. The USB interface also enables the two evaluation boards to communicate with each other, which enables the combination of the RF transceiver to be tuned and tested.

In addition, ADA2200-EVALZ is equipped with a universal LabVIEW software development kit, which includes a library of various ready-to-use LabVIEW programs for different RF transceiver solutions development and testing. The intuitive interface of the LabVIEW platform makes it easy to manipulate various settings and parameters directly, and monitor the performance of the different components at the same time.

Moreover, the evaluation boards have a FPGA function that can be used to interface with external components and customize for system design. The ADA2200-EVALZ FPGA is a Xilinx FPGA, which enables the adaptation of different program algorithms for frequency generation, different modulation schemes, external digital input, etc.

Conclusion

ADA2200-EVALZ is an integrated platform wherein RF transceiver solutions can be developed, tested and optimized quickly and cost-effectively. The fully-integrated hardware platform provided by the evaluation board helps design engineers rapidly create hardware solutions, while the LabVIEW software provides a visual platform to facilitate quick and efficient model development, tuning and testing. Furthermore, the FPGA on board makes it possible to create high-performance, fully-customizable solutions for various communication applications.
