  9. Plating • Plating thickness and galvanic issues • Prototypes • CV • Albuquerque (10 shops) • Production • Mexican Partner (Primary) • New Mexico (18 shops)* FrontEnd System and FeedCone PDR 12-13 FEB 2002

  10. Feeds Chromate Conversion Sealed Junctions Dry Environment Desiccant Pressurized Dry Air Nitrogen Polarizers Minimized by putting all components in dewars Minimize galvanic voltages Moisture & Corrosion Control FrontEnd System and FeedCone PDR 12-13 FEB 2002

  11. Window & Radome • Design for minimum reflections and losses at up to 2:1 BW • K/Q Band Model • Radome: environmental protection, non-absorbent, good UV characteristics • Feed Window: moisture seal, protect against insect/rodent access and nesting • Vacuum Window: Interface feed to receiver FrontEnd System and FeedCone PDR 12-13 FEB 2002
