Ultra Low Phase Noise Analysis & Measurement

准确的时间和频率信号对于包括CNI在内的许多部门和行业都是必不可少的。时间和频率的分配是一种无形的效用，在人们的日常生活中发挥着重要的作用。因此，在不降低输入信号的情况下以高可用性传播精确和准确的信号的能力至关重要。时钟分配放大器从可信的输入射频信号产生多个输出。分配放大器必须表现出超低噪声性能，以提供具有可忽略漂移和高稳定性的强健输出信号，而不会引入与输入信号成比例的任何额外的相位噪声。信号分配器通常用于电网、金融、广播、空间、电信和紧急服务等需要精确和稳定的定时信号的所有行业。输入信号来自可信的来源，如UTC(NPL)，分配器的输出使多个设备能够与输入信号同步。目前，信号分配解决方案提供了令人满意的相位噪声规格，但实现超低相位噪声参数的选择有限。目前可获得的分配放大器主要从海外公司获得，导致英国行业严重依赖进口。其主要目标是开发一种具有最低相位噪声、能够覆盖较宽带宽的分配放大器，以降低成本和简化系统复杂性。然而，这种对进口的依赖带来了产品可用性以及定制产品以满足特定需求的能力方面的挑战。该项目的主要目标是最终完成能够在1 MHz至100 MHz的频率范围内分配信号的超低相位噪声分配放大器的设计和开发。这款产品有两种类型：一种是具有一个输入和五个输出的紧凑型桌面单元，另一个是具有三个输入和十五个输出的1U机架安装单元。主要项目目标包括：*实现与市场上现有解决方案具有竞争力的超低相位噪声规格。*创造两种不同的分配放大器，以满足不同的行业需求。*使科学技术公司成为英国提供这种产品的最佳供应商之一，从而提供竞争优势。

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.
