Why UD Box 5G?
TMYTEK UD Box is an up/down converter with an integrated mixer, an internal local oscillator (LO) as well as optional IF and RF filters that are explicitly made for 5G and satellite applications. Ｗith the built-in LO from TMYTEK's phase-locked oscillator (PLO) product line to ensure excellent phase noise performance, our UD Box makes radio frequency conversion easy and flexible.
Maximize Sub-6 GHz Instruments
TMYTEK UD Box is designed with great interoperability to extend your RF equipment. Labs can save costs on expensive mmWave instruments by making the best use of the existing sub-6 GHz test equipment. The up/down conversion from RF to IF easily addresses the possibilities of mmWave production.

Multi-Channel Research and Applications Made Possible
TMYTEK UD Box comes in two variants, UD Box Single and UD Box Dual, to provide researchers flexibility for various research and application purposes. Built with a shared LO, TMYTEK UD Box is equipped with 100 MHz and 10 MHz clock references to support external synchronization with other devices. As a result, MIMO system development can be realized with multiple sets of UD Boxes while telecom carriers can perform Far Field Assessment Simulation for 5G mobile base stations with two sets of UD Box Dual and TMYTEK's beam tracking solution, saving you time and budget.

FAQ
Does UD Box have an internal local or external reference clock?
Yes, TMYTEK UD Box has an internal reference clock for the internal local oscillator to adjust frequencies. We can also provide this 10 MHz reference clock output to synchronize external instruments with our UD Box.
What is the purpose of UD Box software?
TMXLAB Kit, the TMYTEK GUI integrates most of our products into one single interface. It allows developers to control LO frequencies, channels and reference ON/OFF functions. We also have API ready to help production line automation and research environment with extensive control.
What is the difference between single and dual UD Box?
Our UD Box comes in single and dual-channel variants. The advantage and exclusive features are that you can use two single-channel UD Boxes for non-coherent modulation and demodulation. One as the transmitter (Tx) and one as the receiver (Rx) for long-distance propagation measurement. Dual-channel can be used when you have limited space requirements or do not have distance requirements, such as using it in an anechoic chamber.
Is UD Box tied to specific instruments? If so, what instruments is it compatible with?
No, UD Box is not tied to any brand/instruments. It is compatible with almost all types of signal generators and analyzers available on the market. We have tested UD Box with instruments from Keysight, Rohde & Schwarz, Anritsu, NI, Litepoint, etc, and we are still working on the integration with more instruments. Please do not hesitate to contact us to confirm if UD Box is compatible with your current application scenario and existing instruments.
Can UD Box convert IQ baseband signal to mmWave?
Currently, we do not have IQ products but the UD Box can be customized to convert signal output from mmWave to IQ baseband.

Which frequency bands does UD Box cover for 5G communications (i.e. n257, n260…)?
UD Box RF frequency ranges from 24 to 44 GHz which covers all of the 5G NR FR2 frequency bands from n257 to n261.
I did not see any filter on the RF port for image rejection in the datasheet schematic. Is the image from the IF conversion rejected by a filter in the UD Box?
UD Box is a broadband device so the image rejection filter is not built-in. We have optional filters that you can choose to filter the unwanted signals or we can design a customized filter to fulfill the band you are interested in.
Can I use your amplifier together with UD Box via cable connection?
Yes, you can use one of our amplifiers with UD Box via cable connection.
What is the instantaneous bandwidth (IBW) of UD Box?
Our UD Box IF is from 0.01 to 14 GHz. The instantaneous bandwidth depends on the testing equipment, testing signal type and conditions. For reference, in 5G communication testing, we have tested using 5G NR 64 QAM on. The instantaneous bandwidth was around 100 MHz with an error vector magnitude (EVM) of 3%. On the other hand, we have also tested 4K video streaming. A bandwidth of 800 MHz is used to sustain a throughput of over 2.8 Gbps and an EVM of 3%.
Can UD Box work with Vector Network Analyzers for S21 measurements?
Yes, our UD Box along with our VNA Cal-Kit can upgrade low class/frequency VNA to high frequencies for S21 measurements.
Is it bi-directional?
It converts IF and RF signals in a bi-direction channel.
