This paper has investigated the implementation of a conformal amplifier embedded into a high performance aerospace composite quartz fiber re-enforced polymer (QFRP) matrix. A cyanate ester resin system provided by Lonza (PT-30) was used to encapsulate the quartz fibers (Astroquartz II) and the passive/active elements. This enabled a streamlined aerodynamic functional skin to be formed over the leading edge of an airfoil. Apart from the active amplifier component, a passive bias-tee and power LED were also integrated into the skin. The conformal amplifier performance was measured and found to have low-loss and acceptable impedance matching between 0.01 GHz and 1.0 GHz. The amplifier gain is above 10 dB up to 2.0 GHz. The successful manufacturing process for this conformal amplifier has demonstrated the ability to integrate novel microwave circuits into composite materials on a highly conformal surface.
