Overview
The CVCO55CC-2809-2921 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 2809 MHz to 2921 MHz, with a center frequency of 2865 MHz. The device utilizes a coaxial resonator design and accepts a tuning voltage input between 0.3 V and 4.7 V. Key electrical specifications include a maximum supply current of 25 mA and a typical second harmonic level of -15 dBc. The component is RoHS compliant and designed for surface mount applications.
Feature Summary
- Utilizes a coaxial resonator structure for stable oscillation performance
- Provides precise voltage-controlled frequency tuning across the specified microwave band
- Designed for surface mount integration in compact electronic assemblies
Applications
- Microwave communication systems
- Frequency synthesis circuits
- Test and measurement equipment
Procurement Notes
Verify the specific part number CVCO55CC-2809-2921 against official Crystek documentation to confirm frequency range and tuning voltage specifications. Ensure compatibility with system power supply requirements, noting the 5V supply and 25mA max current limits. Confirm RoHS compliance status if required by project regulations. Cross-reference datasheet parameters for load capacitance and harmonic levels before finalizing procurement decisions.
Selection Notes
Select this component when a fixed-frequency VCO in the 2.8 GHz range is required. Consider the 0.3 V to 4.7 V tuning sensitivity and 25 mA current consumption during circuit design. Evaluate the -15 dBc second harmonic specification against system noise floor requirements. Ensure the SMD package dimensions fit the target PCB layout constraints.
Part Context
This model belongs to the CVCO55 series of Voltage Controlled Oscillators from Crystek Microwave. The series includes various models covering different frequency bands, such as the CVCO55CL-0100-0110 for lower frequencies. These devices are part of Crystek's broader portfolio of frequency control products, which also encompasses quartz crystals, TCXOs, and PLL synthesizers.
Replacement Considerations
