The Design of a 41.6GHz~62.5GHz All-Solid-State Source Module with High Power Flatness

In this article, a 41.6GHz~62.5GHz quadruple source module is presented. The 2 stages of doubler and several filters as well as amplifiers are used to generate sufficient output power. Due to the output power of the last stage amplifier continues to decline at high frequency, a new kind of positive slope equalizer featured with resistive film is introduced to adjust it. Finally, the measured results of the source module show that from 41.6GHz to 62.5GHz, the minimum output power is 23dBm; meanwhile, the power flatness and the harmonic suppression are better than ±0.5dB and 40dBc, respectively.
