Overview
The CVCO55CC-2186-2250 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 2.186 GHz to 2.25 GHz, with a center frequency of 2218 MHz. The device requires a minimum supply voltage of 5 V and utilizes a control voltage range of 0.5 V to 4.5 V. It features a load capacitance of 50 pF and is housed in a surface-mount package measuring 0.500 inches by 0.500 inches (12.70 mm x 12.70 mm).
Feature Summary
- Operates as a coaxial resonator oscillator within the specified microwave frequency band.
- Supports voltage-controlled tuning via an external control voltage input.
- Designed for surface-mount integration in compact electronic assemblies.
Applications
- Microwave communication systems requiring stable frequency generation.
- Test and measurement equipment utilizing voltage-tuned oscillators.
- RF signal processing circuits operating in the 2 GHz range.
Procurement Notes
Verify the specific ordering suffix and pin configuration against the official Crystek datasheet before procurement. Ensure that the supply voltage and control voltage ranges align with your system design requirements. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a fixed-frequency VCO in the 2.186–2.25 GHz range is required. Consider the 50 pF load capacitance for impedance matching networks. Evaluate the 0.5 V to 4.5 V control voltage span against your available tuning circuitry. The SMD package size dictates the available board space, so verify clearance constraints prior to finalizing the design architecture.
