The 637L15005C2T oscillator is a radio frequency (RF) oscillator which is typically used in RF systems and microwave radio applications. It operates with a frequency of 15.005 GHz and has a bandwidth of 10 MHz. The oscillator is able to provide an exceptional noise suppression level, in addition to an extremely stable signal level. It also has a very low harmonic level, which is useful for high-performance applications.
This oscillator is generally used in frequency synthesizer and transceiver applications. Additionally, it can be used as a carrier source in various other transmit/receive systems. As it makes use of narrow bandwidth operations, the 637L15005C2T oscillator is also suitable for use in point-to-point communications, such as WiFi and WiMax signals.
Working Principle
The 637L15005C2T oscillator works on the principle of amplitude modulation, where the amplitude of the signal is modulated to ensure that a uniform waveform is maintained. This oscillator produces a signal of very high stability, as it is based on a varactor-tuned oscillator design. This makes use of a variable capacitance diode in the frequency-determining circuit, which is able to provide excellent spurious suppression and helps to maintain a constant frequency over a wide temperature range.
The oscillator is constructed in a compact housing and uses a voltage-controlled oscillator (VCO) as the output amplifier. This is then coupled with the varactor-tuned oscillator, which is able to maintain the high level of frequency stability. The output of the oscillator is then amplified before being passed through a bandpass filter, which removes any spurious signals which may be present in the signal.
