摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to radio engineering and can be used in transmitting and receiving devices, which u0442u0440u0435u0431u0443u0435u0442u0441u00a0 u0432u044bu0441u043eu043au0430u00a0 precision phase characteristics u0444u0438u0434u0435u0440u043du044bu0445 routes. aim the stability of phase shift of microwave signal.the device contains the adder 1, the escape hole | b 2, optical power dividers and directional couplers 3, the optical fiber 4, u0444u043eu0442u043eu0434u0435u0442u0435u043au0442u043eu0440 5, an optical amplifier 6, an additional u0444u043eu0442u043eu0434u0435 tecton 7 and the optical heterogeneity among 8.as a result u0441u0443u043cu043cu0438u0440u043eu0432u0430u043du0438u00a0 harmonics with different delays u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u0435u0442u0441u00a0 u0432u0437u0430u0438u043cu043du0430u00a0 u043au043eu043cu043fu0435u043du0441u0430u0446u0438u00a0 their phase shifts and the phase of high frequency output signal is reduced from u0430u0432u0438u0441u0438u043cu043eu0441u0442u044c from the electrical length of the channel. 2). s.
