Abstract:

A superheterodyne receiver for the 2 millimeter range was built using fourth harmonic mixing with a first intermediate frequency of 420 mc. The receiver noise figure, the harmonic mixer noise temperature and harmonic mixer conversion loss were experimentally obtained for first intermediate frequencies of 30, 420, and 500 mc. The results are in agreement with earlier work in this Laboratory. An improvement of receiver noise figure of about 3 db can be obtained by applying a forward dc bias to the harmonic mixer. Author
