Precise time and frequency signals are essential for many sectors and industries including CNI. The distribution of time and frequency is an invisible utility that plays an important role in people's daily life. Hence, the capability of disseminating precise and accurate signals with high availability and without degradation of the input signal is vital.The clock distribution amplifier generates multiple outputs from a trusted input radiofrequency signal. The distribution amplifier must exhibit ultra-low noise performance to provide robust output signals with negligible drift and high stability without introducing any additional phase noise in proportion to the input signal The signal distributor is used commonly in all industries where they require precise and stable timing signals such as power grids, finance, broadcasting, space, telecommunication, and emergency services. The input signal is coming from a trusted source such as UTC(NPL) and the output of the distributor enables multiple devices to be synchronised to the input signal.At present, signal distribution solutions provide satisfactory phase noise specifications, but the options for achieving ultra-low phase noise parameters are limited. The distribution amplifiers currently accessible are obtained from mostly the overseas companies, leading to a significant reliance on imports within UK industries. The primary objective is to develop a distribution amplifier with the lowest phase noise, capable of covering a wide bandwidth to reduce costs and simplify system complexity. However, this reliance on imports presents challenges concerning product availability, and the ability to customize products to meet specific requirements.The primary goal of this project is to finalize the design and development of an Ultra-Low Phase Noise Distribution Amplifier capable of distributing signals in the frequency range of 1 MHz to 100 MHz. Two types of this product are envisioned: a compact desktop unit with one input and five outputs, and a 1U rack-mounted unit with three inputs and fifteen outputs. Key project objectives include:* Achieving ultra-low phase noise specifications that is competitive with existing solutions in the market.* Creating two variations of the distribution amplifier to cater to different industry needs.* Establishing ScioTech as one of the best suppliers in the UK to offer such a product, providing a competitive advantage.

精确的时间和频率信号对于包括CNI在内的许多领域和行业至关重要。时间和频率的分布是一个无形的效用，在人们的日常生活中起着重要作用。因此，传播具有高可用性的精确信号并且没有输入信号的降解的能力至关重要。时钟分布放大器从受信任的输入射线传频信号产生多个输出。分布放大器必须表现出超低的噪声性能，以提供具有可忽略不计的漂移和高稳定性的强大输出信号，而不会与输入信号成比例地引入任何其他相位噪声。信号分配器通常在所有行业中使用，在这些行业需要精确且稳定的时机信号，例如电力网络，财务网格，财务，广播，广播，广播，电视，电视，电视，电视，电视，电视，电视，电视，和紧急服务和紧急服务。输入信号来自UTC（NPL）等受信任的来源，并且分配器的输出使多个设备可以同步到输入信号。在目前，信号分布解决方案提供了令人满意的相位噪声规范，但是实现超低相位噪声参数的选项有限。目前可访问的分销放大器主要是从海外公司获得的，从而极大地依赖英国行业的进口。主要目的是开发具有最低相噪声的分布放大器，能够覆盖宽带的带宽以降低成本并简化系统的复杂性。但是，这种对进口的依赖提出了有关产品可用性的挑战，以及定制产品以满足特定要求的能力。该项目的主要目标是最终确定能够在1 MHz至100 MHz频率范围内分发信号的超低相位噪声分布放大器的设计和开发。设想了该产品的两种类型：一个紧凑型桌面单元，带有一个输入和五个输出，以及一个1U机架安装的单元，带有三个输入和15个输出。关键项目目标包括：*实现与市场中现有解决方案竞争的超低相位噪声规格。*创建分销放大器的两种变体以满足不同的行业需求。
