Oscillators: AX7DBF1-148.351648T

Oscillators are electrical components whose purpose is to generate an electric signal that varies periodically in time. They are used to maintain an electrical circuit’s frequency and produce periodic voltages, i.e. oscillate. This article will discuss the application field and working principle of the specific oscillator, AX7DBF1-148.351648T.AX7DBF1-148.351648T is a high-performance voltage-controlled oscillator (VCO) manufactured by KEMAX Technology Corporation. It operates over a broad frequency band ranging from 141.5 MHz to 148.3 MHz and provides more than 1.3 GHz tuning range. It is typically used in fixed wireless access (FWA), wireless local loop (WLL) systems, military communication systems, and global navigation satellite systems. The purpose of a VCO is to oscillate at a varied and adjustable frequency. This is accomplished by generating a nonlinear or linear relationship between the frequency of the output signal and the control voltage level applied to the input of the VCO. In the case of AX7DBF1-148.351648T, it achieves higher frequency performance by using two high frequency active filters in tandem. The first filter is a voltage amplifier, which boosts up the signal to a higher amplitude necessary for the oscillator to start. It is followed by a second filter, which further amplifies and shapes the signal into a sine wave.The AX7DBF1-148.351648T oscillator is designed to be used as a local oscillator in a radio receiver circuit. The oscillator works by receiving a modulated frequency signal from an external source, amplifying it, and then generating an oscillating signal at the required frequency. The signal is then passed through the amplifier and tuned with a variable capacitor (VC) to the desired frequency. A tuning voltage, which is typically between 0 and 5V, is applied to the input of the oscillator to adjust the frequency. A miniature, internal VC is used to provide fine tuning of the frequency within the desired range.The AX7DBF1-148.351648T oscillator offers high frequency stability and robust operation over extended periods of time. It performs at exceptionally low levels of phase noise, ensuring reliable communications over a variety of frequencies. The oscillator also has a low temperature coefficient, meaning that it can operate in a wide range of temperatures without jeopardizing performance.In conclusion, ax7dbf148.351648T is a high-performance VCO ideal for use in frequency hopping and distributed antenna systems, as well as wireless systems requiring good stability and low phase noise. Its high tuning range and excellent frequency stability make it suitable for a wide range of applications.
