Ultra Wide Band (UWB) - The frequency components you need and how this technology is being used to combat COVID-19
Ultra Wide Band or UWB as it's known, is an exciting technology being deployed in multiple applications including the Apple iPhone, cutting edge drone technologies and asset tracking and is even being rolled out to workplaces and medical centers in a concerted effort to combat COVID-19 by enabling social distancing. Our Chief Engineer Chris Watts takes an in-depth look into this technology and recommends the best frequency solutions for use with UWB.
Crystal Parameters Glossary and Specification Guide
This application note gives a brief explanation of the more popular terms used when describing the specifications of quartz crystals along with an explanation of our crystal specifications notations.
How to Select the Right Filter Technology for Your Application
The first part of selecting an RF filter is selecting what technology to use. The main types stocked by Golledge are SAW and Crystal but we also have a range of ceramic resonator and LTCC LC filters.
From Ground to Orbit: Securing the Timing Signal Chain in LEO Constellations
This application note maps the complete LEO satellite communications signal chain — from ground segment uplink through satellite payload to downlink processing — and identifies the optimal TechPoint Golledge frequency control product at each node. It covers clock oscillators (SPXOs), VCXOs, TCXOs, OCXOs, crystal filters, SAW filters, and RTC modules, with key specifications, risk analysis, and application rationale. Engineers selecting frequency components for LEO constellation ground stations, satellite payloads, CubeSats, and GNSS synchronisation infrastructure will find a complete product selection reference and design guidance within this note.
