Abstract :
NIST has upgraded its measurement capability of noise parameters on low-noise amplifiers with a variable termination unit in the 1 to 12.4 GHz range. Such a unit allows improved time efficiency in the noise-temperature measurements used to de-embed noise parameters of amplifiers. We present measured results for noise parameters of a low noise amplifier in the frequency range of 8 to 12 GHz.
