Selection of coaxial and strip-line dielectric support material
Selection of coaxial and strip-line conducting material (metals) Strip-line (0.5 x 14 mm): Al. alloy 1020A H/H Copper 101 H/H BeCu (Brush-Wellman - low Be) Al.alloy 5000 series Strip-line body: Alcoa MIC 6 cast tooling plate (7000 series alloy - Zn) TeCu alloy C109 – OK for helical Al. alloy 6000 series ? Coaxial body: TeCu alloy C109 - low Te or MIC 6 Coaxial centre conductor: BeCu or TeCu
Manufacture of prototypes: John Spencer: MMT precision mechanical workshop Precision manufacturing using specialised manual and NC machine tools – on site expertise Also provides on site specialist electroplating facilities Materials order placed with PR metals (C109 and MIC 6) Sample of BeCu strip received from Brush Wellman UK
