Technical Specification

The Otava Beamformer IC Evaluation Kit allows for the rapid evaluation of the Otava OTBF103, a ground-breaking device for mmW and 5G development, in a lab environment. The kit includes the Otava Beamformer Evaluation Board, a MicroZed SOM based on the Zynq 7010 SoC, supporting hardware and a custom GUI. Using the MicroZed and GUI software, engineers can immediately focus on manipulating the RF signals and evaluating the Beamformer IC. The control interface has been fully implemented and the device can be controlled from a PC using USB or Ethernet. Product Brief (Datasheet)

Otava’s Beamformer IC (BFIC), the OTBF103, is a mmW wideband time-division-duplexing beamformer. The BFIC consists of eight transmit channels and eight receive channels in the 24 GHz to 40 GHz frequency range, which encompasses numerous worldwide 5G bands. Each channel has individual phase and gain adjustment controls and an onboard 4K byte memory that allows for fast operational steering between 64 programmable positions. An SPI control interface (LVDS or LVCMOS) is used for programming the 158 registers and memory locations. The BFIC can be evaluated by using the OTBF103-EVAL board from Otava.

Avnet implemented the control interface using a MicroZed 7010 Zynq module and a GUI that runs on a PC. This enables rapid BFIC familiarization without having to first create custom software.
