Otava Beamformer IC
The Otava OTBF103 IC provides frequency coverage from 24 to 40GHz encompassing the n257, n258, n260 and n261 millimeter wave (mmW) 5G NR bands, with coverage for SATCOM and DoD applications. The wideband IC consists of eight transmit channels and eight receive channels. Each channel has independent 5.6 degree phase and 20dB range gain controls. The IC also includes temperature sensing, RMS power detection, and provides embedded drivers for external control of amplifiers and switches. The high speed digital SPI is operated in LVDS or single ended CMOS mode, and comes with integrated memory. The IC is provided in bare die form, with a size of 9.8 x 4.2mm.

Evaluation tools
Otava’s evaluation kit for the Beamformer (OTBF103-EVAL) has been released. The evaluation kit includes the Beamformer eval board, a MicroZed digital controller with accessories and a software GUI.
OTBF103 Mathworks Simulink Model
Otava and Mathworks have co-developed a Simulink model for the OTBF103 Beamformer. The model enables bit-to-antenna system level simulations, RF signal chain optimization and algorithm development. The model, which is based on measured data, is specifically tailored for antenna array radio modeling. Modeled parameters include performance over operating frequency, VGA gain setting, phase shifter setting, and input/output power level. Please register at the NDA request link on this page obtain the model and additional information.
