ACT RF clock crystals

ACT launch new range of MHz RF clock crystals

ACT have launched their latest range of RF clock reference crystals. The comprehensive product family covers all common RF and wireless frequencies and is the ideal solution for demanding applications. Whilst many manufacturers limit their over temperature stability to -20~-+75°C, the ACT range uses a combination of specialised electrodes, high-precision cut crystal blanks, and tightly controlled...

ACT simulation of crystals and resonators

Technical paper – Simulation of crystals and resonators

In millimetric applications, an oscillator is a common module in many analogue circuits. The following article offers some suggestions of how to model the piezoelectric resonator that is its principal component. The RLC circuit representing the impedance of a crystal resonator is shown by a two-terminal equivalent in figure 1. The circuit above shows, the... View article
