Abstract

PURPOSE:To prevent the deterioration at noise temperature in the frequency band edge, by increasing the gain at the band edge of the parametric amplifier and by compensating the shift from the flat performance of the frequency performance with the amplitude characteristics adjustment of such as amplitude equalizer.
