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.
