Oscillators

Oscillators are electronic devices that generate an oscillation or repetitive signal without an input signal. They are commonly used to generate radio frequencies or other forms of alternating current. The most common type of oscillator is an oscillator circuit, which uses an active element such as a transistor, diode or amplifier and an LC circuit, also known as an LC tank, to produce periodic electronic oscillations.

SIT1602BC-71-18E-66.600000D is a voltage-controlled oscillator (VCO) designed to operate in the ka-band frequency band (17.7 to30.0 GHz). It is a hybrid integrated circuit (HIC) that includes a VCO, a frequency divider and a power amplifier. It provides a high frequency output power of 21 dBm and ultra-low phase noise of -167 dBc/Hz at 10 kHz offset from the centre frequency.

Application Field

SIT1602BC-71-18E-66.600000D can be used in a wide range of applications. It can be used for communications, aerospace, navigation, defence, instrumentation and test equipment. It is also suitable for use in 5G microwave applications, including point-to-point wireless systems, backhaul, wireless broadband, and WLAN. In addition, the VCO can be used for signal amplification in avionics and VSAT.

Working Principle

The working principle of the VCO is based on the linearity of the LC resonant circuit combined with a small injection signal. The resonant circuit is formed by an inductor and a capacitor. When the voltage is applied to this circuit, it produces an oscillating signal with a frequency determined by the inductor-capacitor combination. The injection signal is then used to modulate the frequency of the VCO. The modulation frequency can be adjusted with a voltage control input. This modification changes the frequency of the oscillations and thus changes the output frequency of the VCO.

The injection signal is generated by a CMOS oscillator circuit. The oscillator circuit consists of an inverter with two transistors that provide positive and negative feedback. This circuit constantly generates an oscillating signal of a certain frequency which is then fed into the LC circuit. The LC circuit then increases the frequency of the oscillations, resulting in an output of the desired frequency.

At the output of the VCO is a power amplifier. This amplifies the signal to the desired output power level and also provides increased linearity of the signal. The frequency divider is used to further increase the frequency stability by reducing the jitter or frequency uncertainty.

In summary, SIT1602BC-71-18E-66.600000D is an oscillator designed to operate in the Ka-band frequency band. It is designed for use in a wide range of microwave applications including point-to-point wireless systems, backhaul, wireless broadband, and WLAN. The oscillator uses an LC resonant circuit combined with an injection signal from a CMOS oscillator circuit to produce a high frequency output with ultra-low phase noise. The output is amplified and the jitter is reduced with a frequency divider.
