2.4 GHz low cost low noise amplifier on flexible organic substrate

In this paper a low cost 2.4 GHz low noise amplifier on organic flexible substrate, that is widely used for organic light-emitting diodes (OLED) and flexible printed circuits, is presented. The amplifiers were fabricated by two ways, one with aerosol jet printing technology and the other with copper tape for reduced cost fabrication. Using the aerosol jet printing approach, the amplifier exhibits a measured performance of 12.09 dB gain and 2.4 dB noise figure compared with the copper tape implementation which exhibits 10.55 dB gain and 3.2 dB NF. This demonstration paves the way for low cost ISM sensors on flexible substrates utilized for a variety of functions (LEDs etc.) using digital manufacturing technology.
