| Description: | Presented here is the next generation of the EMBRACE tile, the "hextile". (the previous version "quadtile" is shown at the ASTRON JIVE Daily Image 29-01-2007). Each tile has 6 hexboards mounted on 1 centreboard, including the following items/functions: - 144 vivaldi elements, 72 for each polarization. - 72 low noise amplifiers. - 18 analogue beam-former chips. - Integrated power supply, with voltage and temperature monitoring. - Switchable True-time-delay lines. - Digital control and ethernet communication The power, ethernet communication and RF signals are all transported over the 2 coax cables connected to the centreboard of the tile. The CDC present in the backend seperates these signals. |
