A clock distribution module with low phase noise degradation in a vibration environment

Abstract

A clock distribution module with low phase noise degradation in a vibration environment includes a housing, At that top of the outer wall of the shell, a plurality of output interfaces are arranged, At a position close to that right side of the bottom of the out wall of the housing, an input interface is arranged, A top and a bottom of that inner surface of the shell are fixedly connected with a multi-layer printing board through a plurality of pressing strips, A supply circuit is arranged on that front surface of the multilayer printed board from bottom to top at a time, power dividing circuit, AMPLIFIER CIRCUIT AND MICROWAVE CIRCUIT, The power dividing circuit comprises a first two-power divider, a second two-power divider, a first four-power divider, a second four-power divider and a third four-power divider. The amplifying circuit comprises a plurality of high isolation amplifiers. The microwave circuit comprises a coupler, a detector and a plurality of microwave filters. The invention relates to the technical field of clock systems. The device solves the problem that the radar system clock system needs to adopt a large-volume vibration absorber to reduce the phase noise deterioration under the vibration condition.

Description

technical field [0001] The invention relates to the technical field of clock systems, in particular to a clock distribution module with low phase noise deterioration in vibration environments. Background technique [0002] The clock system is mainly used in units that require a unified time for production and scheduling, such as: electric power, airports, light rail, subways, stadiums, hotels, hospitals, troops, oil fields, water conservancy projects and other fields. The large-area clock system is mainly composed of a master clock and multiple slave clocks. Clock systems are also widely used in communication and radar systems. In order to reduce the impact of vibration on phase noise in conventional clock systems, vibration reduction systems are usually added to support them. Or a bracket, but it will increase the volume. The current communication and radar system clock systems need to use a larger volume damping device under vibration conditions to reduce the problem of ph...
