SDR-KIT 2400T2R4 is two-channel transmitter and four-channel receiver radar kit in K-band. Its center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 24-26 GHz. The signals are transmitted in a time division multiplexing manner.The maximum detectable range is about 42-m for 1-sm of RCS.
The 2400T2R4 is designed to support digital beamforming and MIMO capabilities for applications in direction of arrival (DOA) measurement, radar interferometry, digital beamforming and MIMO phased-array radar. It is suitable for human activity monitoring, occupancy sensing, gesture sensing, and tracking of 3-D trajectory.
Typical output power of the transmitter is 22 dBm. Six 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 great 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 signals are transmitted in a time division multiplexing manner.
The FPGA-based processor module functions as a micro controller, processor and power management unit and offers ultimate design flexibility with industry-leading programmable logic. It has four 40-MSPS ADCs to support the four 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.
