BJ-187.500MBE-T Crystals, Oscillators, Resonators

Oscillators are components that produce periodic output waveforms over a predefined frequency range. The BJ-187.500MBE-T oscillator is used primarily in microwave applications such as high-frequency radar and communications systems. This article will discuss the application field and working principle of the BJ-187.500MBE-T oscillator.

Application Field

The BJ-187.500MBE-T oscillator is specifically designed for high frequency microwave applications. It can provide stable signal sources over the frequency range of 60 to 500 MHz. The oscillator is capable of providing a signal with output power up to +17 dBm. It is designed to operate under severe environmental conditions and offers excellent RF shielding and isolation from external interference.

Working Principle

The BJ-187.500MBE-T is a voltage controlled oscillator (VCO). It is designed to generate an output signal by using an input voltage that is applied to a tuned circuit. The incoming signal is amplified, filtered, and then fed back to the tuned circuit. The signal then oscillates at a frequency that is determined by the tuned circuit parameters. This oscillating signal, known as the output signal, can then be used in the desired application.

The BJ-187.500MBE-T oscillator uses a hybrid combination of a quartz crystal, ceramic resonator, and a varactor diode. The frequency of the oscillator is determined by the resonator and the varactor diode acts as a frequency controlling element. The voltage applied to the varactor diode can be used to adjust the oscillation frequency. This feature allows the oscillator to be frequency-agile and provides frequency control with an accuracy of +/–0.1%.
