Antenna gain-to-noise-temperature (G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and the RF chain noise temperature from the antenna terminals to the receiver output. WebPasternack's Noise Figure - Noise Temperature Calculator will produce either noise figure or noise temperature, depending on the input type. Calculation Reference Temperature: Result: Noise figure (NF) measures of degradation of the signal-to-noise ratio (SNR), caused by components, such as amplifiers, in an RF signal chain.
