SDR-KIT 2400AD is an advanced low-power and compact software-defined single transmitter and single receiver radar kit in K-band. It is suitable for human activity monitoring, vital-sign detection, gesture sensing, and many other indoor and outdoor target detection and imaging.


Its typical output power of the transmitter is 18 dBm. The maximum detectable range is about 45-m for 1-sm of RCS. Two single-ended SMA female connectors are installed for easy connection to external antenna units.


Detailed Information

RF Module

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.

Processor Module

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 receiving channel. 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.
