Rapid Prototyping of 3D Printed, High Aspect Ratio, Low Noise Amplifier for Active Handheld Sensor Devices

In this paper, we report the use of additive manufacturing methods to fabricate a high aspect ratio, low noise amplifier (LNA) for handheld active sensor device operating at up 1 GHz. The new form factor LNA incorporates modification square-shaped commercial off-the-shelf (COTS) into 5:1 ratio without loss in RF performance. For rapid prototyping, employ both subtractive and technologies, such as milling, extrusion-based syringe printing, aerosol jet printing techniques small devices. demonstrated 20% smaller factor, gain 25 dB, an NF less than 3 dB over frequency range GHz, comparable COTS LNA.
