Reduced-size low noise-low power consumption amplifier designs for communications and RF applications

Low-noise amplifiers are extremely significant components in most RF cellular and communications devices. While current design techniques achieve either low noise or high gain, exclusively, little research has been done to reduce their power consumption while simultaneously meeting both of the aforementioned objectives. This paper presents important techniques for the design and development of spatially compact amplifiers that simultaneously provide low noise figure, high gain, low-power consumption, and low VSWR. The design method is illustrated by the realization of both distributed and discrete amplifier circuits centered in the 1.8 GHz frequency range.
