ATAKSTK511-9 is a high-performance RF evaluation and development kit, board developed by ATAK Tech. It provides powerful capabilities for learning, testing and demonstration for various RF applications.

ATAKSTK511-9 mainly consists of an RF module, an observation module, and a host board.

The RF module includes an AD9346 quadrature modulator, a power amplifier, an RF synthesizer, an ADF5355 synthesizer, an SD card-like interface and a GPIO interface.

The observation module consists of two ADCs, two DACs, two ADF5356 frequency synthesizers, two quadrature demodulators, two programmable low-noise amplifiers (LNAs), two synchronous low-pass filters (LPFs), an independent signal generator, and a USB controller.

The host board includes a high-speed CPU, a 32-bit ADCs, a USB controller, a 16-bit DACs, a 128KB SRAM, and an 8-bit NOR Flash.

The main purpose of ATAKSTK511-9 is to provide an open-ended platform for evaluation, development and demo of various wireless systems. It can be used for 3G/OFDMA, WiMAX/DCM, LTE, 802.11, Bluetooth, GPS, GPRS, BC and other high-reliability RF signal sources.

ATAKSTK511-9 also features several measurement capabilities such as wide-band scanning, spectrogram measurement, pulse-width measurement, frequency-hopping measurement, as well as high-speed switching test.

The overall working principle of ATAKSTK511-9 is relatively simple and can be explained as follow. First, the signals generated by the onboard transceiver are mixed with the internal reference clock to form a frequency-modulated signal with a certain frequency deviation. The synthesizer then filters and amplifies this signal, and sends it out via the built-in antenna. The signal is then received by the receiver, and downconverted to its original form. After various types of signal processing are performed, the data is fed into the internal FPGA to be processed by the user.

In summary, ATAKSTK511-9 is a highly versatile RF evaluation and development kit, board with a powerful measurement capability and a wide range of applications. It is capable of testing and verifying a variety of wireless systems in an effective way, which can significantly improve the efficiency of device development and demonstration.
