Crystals
MP073A is a crystal oscillator designed to achieve superior performance in mobile radar applications with features like wide frequency range, fast start-up response and high stability. It is well suited to navigation systems, automotive navigation and avionic applications. In this article, we will discuss the application field and working principle of MP073A oscillator.
Application field
The MP073A was designed to suit two application fields: radar and navigation. As a radar oscillator, it offers superior performance in terms of fast start-up response and wide frequency range. It is well suited for automotive radar applications such as ESR/FCW systems and for avionic applications such as mission critical systems. As an oscillator for navigation applications, MP073A can be used for positioning, navigation, and other location-based services. It is designed to achieve high accuracy and stability in these applications.
Working principle
MP073A uses a YIG-based oscillator circuit to achieve its performance in mobile radar applications. It employs an adjustable frequency synthesizer based on a set of inductors, capacitors and resistors to control the frequency of the oscillator circuit. The desired frequency is set by adjusting the calibrated inductors and then a stabilization process is executed to fine-tune the frequency. The improved stability is provided by the triple-loop design with a phase-locked loop circuit and a voltage-controlled oscillator.
MP073A is also equipped with a temperature compensation algorithm that compensates for temperature drifts due to variations in the environment. This algorithm helps to maintain the stability of the oscillator over extended periods of time even in high temperature environments. It is also equipped with an adjustable output power range, allowing the oscillator to be operated at the necessary power level for the application.
In conclusion, MP073A is an excellent choice for mobile radar and navigation applications due to its high performance and stability. It employs an adjustable frequency synthesizer, temperature compensation algorithm and voltage-controlled oscillator which enable it to provide accurate frequency control and stability in challenging conditions. This makes it a reliable choice for mission and navigation critical applications.
