FMCW Radar Transceivers

The RS3400 series is a family of synthesized X and K band FMCW radar front end modules. They are designed according to previously proven concepts for intrinsic safety resulting in highly reliable units with low power consumption.

The RS3400 series is very flexible and can be used in several different configurations. The frequency is digitally controlled via a standard, 3-wire serial interface, which programs a modern high performance synthesizer circuit. The synthesizer can use either an internal or external reference signal.

A basic interface, the CO1000A/00, for controlling the unit through RS-232 or USB from a PC for evaluation is available. This controller board allows for control of basic transceiver features, while allowing for easy processing and interpretation of the output using your own software packages or instrumentation.

We also sell a complete kit for evaluating our K-band front ends which includes the front end, controller board, a 20 dB horn antenna and a connector. More details can be found here. Please use the part number FMCWKIT when ordering.

CO1000A/00 Controller Board

This controller board is pre-loaded with basic control software allowing for easier evaluation and testing of our FMCW sensors. We do not supply any type of extensive software for the processing of output signals. The integrated software we do supply can perform basic control and data recording functions.

The user will need to write their own signal processing algorithms using a package such as MATLAB or LabVIEW. This is due to the many different applications and requirements that are possible for this sensor, making it extremely difficult to develop a package useful in all situations. Please review the evaluation kit user guide carefully so that you are clear as to the capabilities of our system, and as to what you will have to do to make it work for your needs.
