XLL735040.000000X Application Field and Working Principle
Oscillators refer to circuits that, with the help of energy supplied externally, will oscillate stably with fixed frequency and amplitude. XLL735040.000000X Oscillator, assembled using the voltage controlled crystal and YIG oscillation technology, has been widely utilized in broadband microwave communication systems. The external components of this product determines its frequency range.

Application Field
The XLL735040.000000X Oscillator is capable of achieving a strong output power and highly precise frequency. It is widely used in various application like military radio, telecommunication systems and communication radios. For 2GHz-18GHz communication systems, this type of oscillator can be used as a local oscillator or as a tri-branch oscillator.

Working Principle
XLL735040.000000X Oscillator is a functional block whose main purpose is generating a steady oscillation signal at a specific frequency. The working principle of this product can be simply explained by the following contents:

1. Low-frequency units
The low-frequency units are embodied by a voltage-controlled crystal oscillator (VCXO) and amplifiers, capacitors and resistors. It is composed of an active RC (resistor-capacitor) resonance circuit which determines the oscillation frequency. A temperature-compensated quartz resonator, the major constituent of the VCXO, will drive the RC oscillation circuit to oscillate at a specific frequency.

2. High-frequency units
The high frequency (or medium frequency output) unit is composed of YIG (yttrium iron garnet) saturable-reactor magnetron as the core, amplifiers, capacitors and inductors. The YIG influences the output power and frequency with its performance.

The conclusion
The XLL735040.000000X Oscillator makes use of VCXO and YIG technology to successfully output a fixed oscillation frequency with high precision. The components within it determine the frequency range and output power. It is widely used in military radio, telecommunication systems and communication radios as a local oscillator or tri-branch oscillator.
