SDR-KIT 2400AD2 is an advanced low-power and compact software-defined one-channel transmitter and two-channel receiver radar kit in K-band. It is designed to support interferometric radar and direction of arrival (DOA) measurement. It is suitable for human activity monitoring, occupancy sensing, gesture sensing, and many other indoor and outdoor monitoring.
Typical output power of the transmitter is 18 dBm. Three single-ended SMA female connectors are installed for easy connection to external antenna units.
The RF module is implemented with phase-locked loop (PLL) to achieve linearity in frequency modulations. The center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 24-26 GHz.
The FPGA-based processor module functions as a microcontroller, processor and power management unit and offers ultimate design flexibility with industry-leading programmable logic. It has four 40-MSPS ADCs to support the two receiving channels. A high-speed USB peripheral controller enables digitized raw data streaming to a memory storage for post-processing. It interfaces with the RF module with a 24-pin flat flex cable (FFC) to form a standalone system.
Graphical User Interface
The graphical user interface (GUI) allows the flexibility and adjustability in selecting desired signal waveform, center frequency, bandwidth, sampling rate, filtering, display parameters, and record/export I/Q data.
