Crystals are an integral part of almost all electronic devices. They are used to generate an electrical signal at a very specific frequency, which helps regulate the clock rate for processor based components. In order to be effective in an application, the crystals must be designed and manufactured to have the best electrical performance possible. Therefore, a variety of designs have been developed over the years to meet these demands. One such design is the ECS-250-20-7SX-TR crystal, which is specifically designed for transceiver applications.
The ECS-250-20-7SX-TR crystal is constructed of four dielectric layers of metalized ceramic. Its innermost layer consists of a quartz crystal, which provides the base frequency range. A thin insulating layer of metalized ceramic encloses the quartz crystal and cuts off the unwanted frequencies. The outer layers include a metal ground plane and a top layer of metalized dielectric ceramic which further suppresses any unwanted frequencies. This design increases the loading of the crystal and provides an improved impedance match and enhanced electrical performance.
The working principle of the ECS-250-20-7SX-TR crystal is based on the fact that quartz crystals possess a natural frequency at which they vibrate, known as the series resonance frequency. When a current is applied to the crystal, the quartz resonates at its natural frequency and produces an electrical signal called a series resonance frequency oscillation. This oscillation is then amplified to the desired frequency and used for frequency control in electronic circuits.
The ECS-250-20-7SX-TR crystal is particularly suitable for transceiver applications that require a high frequency accuracy and low power consumption, as it has very low power consumption and good frequency stability over temperature. Additionally, this crystal also offers a low residual phase noise, which is important in order to maximize the signal to noise ratio. Furthermore, its high robustness makes it an excellent choice for applications such as VHF and UHF transceivers.
The ECS-250-20-7SX-TR crystal is one of the best designs available for reliable and efficient transceiver applications. Its efficient design and superior electrical performance make it an ideal choice for high frequency and low power consumption applications. Thanks to its robustness and excellent frequency stability over temperature, this crystal is suitable for a wide range of transceiver applications, from VHF and UHF to two-way radios. As such, it is one of the most reliable and versatile crystals available in today’s market.
