Crystals are solid materials formed by the regular arrangement of atoms, molecules or ions. They can be used in various fields such as electric circuits, electronic communication and optical systems. The FA-238 27.1200MB-W is one such crystal that is extensively used in radio-frequency frequency applications.
This type of crystal oscillator is of a small size, low power consumption and high-stability, which makes it suitable for both military and commercial applications. It features an accurate tuning range and is perfect for applications where lower frequency stability is required.
The FA-238 27.1200MB-W oscillator is composed of a quartz crystal and an encompassing housing. The crystal is cut to a precision flat angle, thickness and is mounted in a hermetically sealed housing, which is further surrounded by a ceramic capacitor. The quartz crystal is typically cut between 24-30°, depending on the required frequency stability for the application.
The crystal and capacitor are connected in a parallel resonance circuit and connected to a common-base emitter transistor amplifier. The crystal provides the balancing capacitance required to achieve the desired high-precision frequency stability.
When the oscillator is powered, the transistor amplifies the crystal\'s signal and feeds it back to the crystal. This feedback signal creates a continuous oscillation and the desired frequency is maintained. The quartz crystal is in resonance due to the electric and magnetic fields and therefore the oscillator produces very a stable frequency.
The FA-238 27.1200MB-W crystal oscillator has a wide range of applications. It is used in military systems such as radios, navigation systems and remote sensing equipment. The frequency accuracy and stability offered by this type of oscillator is also useful in high end precision instrumentation and calibration systems.
