The OTPM is a 2D 64-element active antenna array that provides azimuth and elevation steering with full amplitude and phase control for each antenna element. The array contains the Otava RF beamformers and 64 vertical and 64 horizontal antenna elements, power optimization and thermal reporting, digital control and RF feeds. At the backside of the module box, four SMA ports for transmit and receiver, each with H and V outputs, are available for further each of connections to receiver and transmitter chains.

An AMD-Xilinx Zynq controller resides in this box, enabling direct access to the beamformer chipsets to control the device configuration through serial port interface (SPI). The controller’s direct access to variable phase and gain delay enables the steering of the beams. Built in memory residing inside the beamforming chip allows storing and easy access of multiple phase and gain weights.
