Voltage Controlled Oscillators (VCOs) refer to an oscillator whose oscillation frequency can be adjusted or modulated by changing the amplitude of an input voltage. The most popular applications are in clock and timing signals generation. VCOs have a wide range of applications and are widely used in many fields such as communication systems, instrumentation, radars, radios, satellites, and time bases.

The CVCO55BE-1750-2150 is a Voltage Controlled Oscillator (VCO) that operates from 1750 to 2150 MHz, making it an ideal choice for applications such as satellite TV, cellular base stations, point-to-point radio, and frequency synthesisers. This VCO is offered in a hermetically sealed 6-pin ceramic package with a 7/16" x 7/16" footprint. It has a minimum tuning voltage of 0 V and a maximum voltage of 13.3 V. It has a low phase noise level and a low supply current of 4.2mA.

The working principle of the CVCO55BE-1750-2150 is based on a voltage-controlled negative resistance oscillator (VCNR), a type of electronic oscillator. VCNRs are driven by a sinusoidal signal generator and the output frequency is adjusted by changing the amplitude of the sinusoidal signal. VCNRs employ a negative resistance to achieve oscillations in which the magnitude of the stored energy is minimum. This enables the oscillator to achieve wider frequency tuning range and higher power efficiency with negligible supply current consumption.

The CVCO55BE-1750-2150 operates with a supply voltage from 4.75 to 6.75 V and features a linear tuning voltage from 0 to 13.3 V. The output power of the VCO is monitored by its own power detector, providing accurate power control without the need to use a separate power detector. The VCO also features a differential oscillator architecture which provides excellent phase noise and stability over temperature.

The CVCO55BE-1750-2150 is also equipped with built-in frequency multiplication and division, which makes it well suited for applications that require higher frequency than the 1750-2150 MHz tuning range. The multiplication and division factors are both internally adjustable, giving users further flexibility and convenience. The VCO has an excellent linearity and low phase noise, making it ideal for high-bandwidth applications.

In summary, the CVCO55BE-1750-2150 is a Voltage Controlled Oscillator (VCO) that operates from 1750 to 2150MHz and has a low phase noise and low supply current. Its main applications include satellite TV, cellular base stations, point-to-point radio, and frequency synthesisers, and it features a built-in frequency multiplication and division. The VCNR oscillator technology gives the VCO a wide range of tuning and excellent linearity for high-bandwidth applications.
