Abstract :
A technique is presented to calculate the noise figure and available power gain for electricially small antenna amplifier circuits over a wide bandwidth. The method permits reasonable predictions of circuit performance solely from the manufacturer´s transistor data, i.e., without resorting to extensive measurements. Results for a system designed for 10 kHz to 500 MHz coverage are presented. The agreement between the calculated and measured noise figures and available power gain is within 3 dB over most of the frequency range.
