Abstract: Configuration of a connection between an even-harmonic mixer and a filter is simplified, thereby enabling size reduction. An even-harmonic mixer and a high-frequency bandpass filter are connected to each other via a transmission line, thereby forming a filter-integrated even-harmonic mixer. The length of the transmission line is set so that impedance on the transmission line side as viewed from a connection point between the even-harmonic mixer and the transmission line is approximately 0 for a frequency fLO of a local oscillation signal. This allows elimination of an open stub which is used in a conventional even-harmonic mixer and of which the line length to provide equivalent grounding for the frequency fLO is about 1 mm. Thus, the connection portion between the even-harmonic mixer and the high-frequency bandpass filter is simplified and a compact circuit layout for the filter-integrated even-harmonic mixer is obtainable.

Abstract: A method and an arrangment for reducing phase jumps in a frame synchronization signal when switching between synchronization signal when switching between synchronization reference sources are disclosed. A new reference signal to which each of the two reference sources (signals) are phase locked, and has frequency n times the respective reference signal, is generated. A selection signal selects the new reference signal to be used, and the selected one is then divided back to its original frequency creating an input signal to a phase-locked loop generating the resulting frame synchronization signal. In this way, the maximum phase jumps are reduced from one period of the original reference signals to one period of the new reference signal. The invention is particularly applicable for reducing phase jumps on a master frame synchronization signal in a PDH system.
