RO3144E-2 Crystals, Oscillators, Resonators

Resonators

A resonator is a device or system that displays resonance or the ability to absorb energy when excited by a specific system or device. Resonators are widely used in a variety of fields and applications, including electronics, acoustics, telecommunications, and more. One of the most commonly used resonators is the RO3144E-2 resonator.

The RO3144E-2 resonator is a piezoelectric crystal that is designed to be used in the range of 25 to 500 MHz. It is capable of operating in temperatures ranging from –55°C to +85°C and is constructed of a ceramic chip and a metallized cap. The resonator has a low insertion loss, a wide bandwidth, high Q-factor, and a relatively small size.

Application Field

The RO3144E-2 resonator is commonly used in radio frequency applications, such as radios and receivers. It can be used for frequency control, filtering, and amplitude control. The resonator is also used in television receivers and wireless communication systems. It is also commonly used for wireless applications, such as GPS receivers and wireless local area networks.

Working Principle

The working principle of a RO3144E-2 resonator is based on the effects of piezoelectricity. When a voltage is applied to the resonator, it vibrates at a frequency determined by the voltage. This vibration causes the piezoelectric crystal to deflect, which results in a frequency shift. The resonator will then resonate at the desired frequency.

The resonator has an external capacitor and inductor, which can be used to tune the frequency of the resonator. The combination of these two components creates a resonance frequency, which can be adjusted to achieve the desired frequency. The capacitor and inductor are also used to control the Q-factor, which is the measure of how efficiently the resonator oscillates at the desired frequency.

In addition to the external components, the resonator also has an internal device called a varactor. This device is used to adjust the operating voltage of the resonator. This allows the resonator to operate over a range of frequencies and allows the resonator to be tuned for various applications.

The RO3144E-2 resonator is a versatile device that can be used in many different applications. It is used in radio and television receivers, as well as in wireless communication systems. It is relatively easy to tune and is highly reliable. It is also an economical choice for many applications.
