Introduction to VCOs (Voltage Controlled Oscillators)

Voltage Controlled Oscillators, commonly referred to as VCOs, are a type of oscillator where the frequency of the output signal is directly proportional to the input voltage. This makes VCOs extremely useful for precision applications, such as in communications systems, where it is critical to ensure that the signal remains within specific boundaries. In addition, VCOs offer robust performance and accuracy, making them well-suited for demanding applications.

CRBV55CL-0072-0076 application field and working principle

The CRBV55CL-0072-0076 is a Voltage Controlled Oscillator (VCO) belonging to the series of Crystek’s high-performance VCOs. This series of VCOs is designed to provide a high level of performance and stability in a wide range of frequency and temperature conditions.

The CRBV55CL-0072-0076 is a broadband VCO that offers a wide frequency range of 0.72 - 0.76 GHz. It has an output power range of +13 dBm (2 mA) to -20 dBm (-20 mA) with a linearity of ± 2dB. This wide frequency range, combined with its high linearity, make the CRBV55CL-0072-0076 well suited for applications such as microwave radios, point-to-point communications systems, telecom equipment, instrumentation, and satellite communications.

The CRBV55CL-0072-0076, like other VCOs, is based on a principle whereby a voltage applied to a resonator is converted into a frequency output. The oscillation frequency is a function of the resonator and the applied voltage, but can be tuned to different frequencies by varying the applied voltage. The oscillator produces a sine wave output which is then filtered and amplified for use in the application.

Conclusion

The CRBV55CL-0072-0076 is a high-performance VCO with a wide frequency range and excellent linearity. Its applications span industry sectors from base station and mobile radio to satellite communications systems, instrumentation, and remote sensing. Due to its broad frequency range and accuracy, the CRBV55CL-0072-0076 is well-suited for demanding applications that require precision frequency control.
