Crystals are essential for the successful operation of microwave radio equipment. ECS-122.8-20-1 is a crystal designed specifically for use in microwave radio applications. In this article, we’ll discuss the application field and working principle of this crystal.

The ECS-122.8-20-1 is a high-frequency oscillator crystal suitable for use in microwave radio applications and is designed for operations up to 18GHz. An oscillator is usually required in microwave radio applications in order to maintain a stable and uninterrupted communication link. The ECS-122.8-20-1 crystal has a nominal frequency of 122.8MHz and is a double-pull configuration, with a reliable frequency tolerance of ±20ppm at 25°C. This means that the frequency can vary by up to 20ppm from the nominal 122.8MHz.

When the crystal is included in an oscillator circuit, it is necessary to apply a voltage to the crystal in order to maintain a stable frequency. This voltage is usually between 0.5V and 1.5V, with larger crystals usually using higher voltages. When powered, the crystal oscillates at the specified frequency which is determined by its cut angle and the temperature of its environment. The oscillation is maintained by the positive feedback from the resonance and the resistance of the crystal. When the voltage is removed, the oscillation stops.

ESC-122.8-20-1 crystals can be used in many applications, including military radios and high-end satellite communications, since their high reliability and stability make them ideal for such applications. They also have a wide operating temperature range, from -40 °C to + 85 °C, which makes it suitable for use in harsh environment conditions. Furthermore, the narrow frequency tolerance means that the crystal can be used to precisely generate a signal of a certain frequency, which is important for ensuring stable and uninterrupted transmission.

The ESC-122.8-20-1 crystal is also suitable for use in handheld radios and cellular base-station communication. Its small size makes it suitable for use in compact applications, such as mobile phones, while its wide operating temperature range makes it suitable for use in extreme temperatures. Its high stability and low phase noise also make it suitable for use in frequency synthesizers, allowing a wide range of frequencies to be synthesized with high accuracy.

In conclusion, ESC-122.8-20-1 is an ideal crystal for use in microwave radio applications, due to its wide operating temperature range, narrow frequency tolerance, and high stability. The crystal can be used to generate a stable signal of a certain frequency, making it ideal for military radios, satellite communication and handheld radios, as well as frequency synthesizers.
