Abstract :
According to the needs of modern wireless communication systems, Point to Point PtP Radio equipment have to support complex modulation formats at high data rates using carriers in the millimetre-wave frequency range. As a result, frequency synthesizers are required to perform broadband tuning, low phase noise and high frequency stability (versus thermal and mechanical shocks). Trying to meet the above mentioned goals, a 38 GHz synthesizer able to support a 2xSTMl (2×155 Mbps) in cross polar configuration was studied and developed. Design details and interesting test results are reported in the summary paragraph.
