Testing the second generation hextile
| Submitter: | Pieter Benthem |
| Description: | Presented here is the next generation of the EMBRACE tile, the "hextile". 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. This second generation design is the last one before entering the full production stage of Embrace hardware. 250 hextiles will be produced and tested at Major Electronics. First tests look good, intensive testing is in progress. |
