Abstract

The symmetrical load is for comparatively high level power UHF. The load is formed on a mandrel and consists of a layer of absorbent silicon carbide mixed with a powdered refractory material such as alumina or beryllium oxide(1). The mandrel shape is that of a steep sided pyramid and is matched by the absorbent layer. This is covered by a layer of, preferably, copper(4). The mandrel is finally removed, the load being enclosed within a cooling chamber(10) provided with inlet and outlet ports for a coolant liquid.
