Abstract
A multiplexer is constructed, which has a stable volume over its thermal operating range. A composite material is used that utilizes a fabric having fibers of opposing coefficients of thermal expansion. Such fibers are assembled at an angle to each other so that resulting expansion and contractions counter act and cancel. One of the fibers is selected for its high thermal conductivity and extends over the length of the multiplexer to form a heat dissipating path.
