Fixed inductor resonators (also known by their part number 264R7C) are typically used to generate frequency reference signals. These devices feature high stability over a wide range of environmental conditions. They contain self resonant coils and a non-magnetic frequency adjusting element in order to generate a precise frequency reference. In certain applications, such devices are used to provide high sharp points in the frequency response of a filter, or to form a notch filter in order to reduce interference from unwanted signal sources.
The device works through a process known as ‘self-resonance’. This technique brings the inductor coil into resonance with a precisely-selected value capacitor. When in resonance, the inductor has a steady-state value of current and voltage. Depending on the device’s design, this voltage and current could be used as a signal source or used to shape a frequency response.
The device operates in one of two different resonance modes: positive and negative. In negative mode, the capacitance and inductance of the inductor create a voltage drop while the inductor is saturated at the operating frequency. In positive mode, the inductor’s capacitance and inductance combine to create a voltage rise while the inductor is saturated. In either case, the device’s resonant frequency is determined by the value of its inductance and capacitance.
In order to create a precise frequency reference, various components must be in place. An inductor, a capacitor, and a resistor are the main components. The inductor and capacitor are typically placed in parallel, while the resistor is placed in series with them to form a LC tank circuit. The frequency of the LC tank circuit is dependent on the values of its components. By varying these values, the resonant frequency of the LC tank circuit can be adjusted.
In practical applications, the device is typically used to generate frequency reference signals for different types of equipment, such as receivers, transmitters, and wireless components. They are also used to provide high sharp points in the frequency response of a filter, or to form a notch filter in order to reduce interference from unwanted signal sources. Furthermore, the device has low power consumption and is suitable for providing frequency references in small size equipment.
The 264R7C part (or fixed inductor resonators) is a high precision frequency reference device. It features high stability over a wide range of environmental conditions and is typically used to generate frequency reference signals. By placing the inductor and capacitor in parallel with a resistor in series, a precise frequency reference can be generated, which can be used in numerous pieces of equipment.
