Key Features and Benefits

Our mmW-SDR solution is engineered to meet the demanding requirements of wireless communication and sensing. We understand the importance of speed and precision in these fields, which is why we have prioritized the following features: fast beam switching time, rapid T/R switching time, and wide beam steering angle.

Fast beam switching time

With a typical switching time of just 2 ms (Ethernet) or 2 μs (SPI Interface), our solution allows for rapid and accurate beamforming.

Fast beam steering time

Our typical T/R mode switching time is just 10 ns (GPIO), enabling quick and efficient transmission and reception.

Wide beam steering angle

TMYTEK’s 5G Beamformers offer 3D beamforming. The steering angle is ± 45° both vertically and horizontally.

What mmW-SDR can do for you?

The mmW-SDR was built specifically to help unleash your creativity when researching and investigating various communication modes, such as 5G FR2, O-RAN, radar telecommunications, NTN (NTN (None Terrestrial Network), JCAS (Joint Communication and Sensing), JCR (Joint Communication and Radar Sensing), JRC2LS (Joint Radar Communication, Computation, Localization, and Sensing), and more.

Inside mmW-SDR

5G Beamformers

The mmW-SDR platform supports advanced beam management and tracking using our beamformers and 5G technology, and includes a 28/39 GHz beamformer for experimenting with advanced beam management and tracking capabilities. The BBox One is a base station with a 4x4 array antenna and the BBox Lite is ideal for UE research with a 1x4 antenna.

Broadband Frequency Converter

The UD Box 5G extends research capabilities to mmWave frequency bands, supporting RF spectrum ranges of 24-44 GHz with IF of 0.01-14 GHz and IBW up to 800 MHz, with excellent EVM performance for advanced research applications.

Software Defined Radio

With the mmW-SDR platform, exploring advanced topics such as beamforming, beam-steering, multi-Gbps throughput, FMCW radar, FR2 deployment, and more is as simple as connecting your familiar SDR to the UD Box and BBox.


A complete set of APIs, with multi-language support, control the mmWave UD Box and BBox, which can be easily integrated into your SDR. Achieve an even higher level of integration with LabView by incorporating the NI Ettus X410. Support for OpenAirInterface (OAI) and GNU Radio will be available soon.

NI Ettus USRP X410

The NI Ettus USRP X410 is a powerful multi-channel software-defined radio that can handle frequencies from 1 MHz to 7.2 GHz. It offers a two-stage architecture with four independent TX and RX channels, each with 400 MHz bandwidth. TMYTEK and NI are solution partners in providing cutting-edge mmW-SDR solutions.


Channel Sounding for mmWave Modeling

“The integration of these high gain steerable beamformers as a part of the channel sounder helps to more easily separate specular multipath components of the propagation channel while suppressing unwanted diffuse MPCs, allowing for accurate mmWave channel characterisation.”
