• Utilizes a compact surface-mount QFN-16 package for efficient PCB integration
• Delivers consistent output power with low phase noise characteristics

Applications

• Microwave communication systems
• Frequency synthesis circuits
• Test and measurement equipment

Procurement Notes

Verify the specific tuning voltage range requirements against your circuit design, as this model specifies a 0.5 V to 4.5 V DC input. Confirm that the 5V supply voltage aligns with your system's power distribution network. Ensure the SMD package dimensions fit within your board layout constraints. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Validate thermal management strategies for operation within the specified temperature range.

Selection Notes

Choose this component when a fixed frequency range between 2300 and 2450 MHz is required. Consider the 30 mA current consumption for power budget calculations. The 3 dBm output power may necessitate additional amplification depending on downstream stage requirements. Evaluate the -100 dBc/Hz phase noise against system sensitivity specifications. The 22 pF load capacitance should be accounted for in impedance matching networks.

Part Context

This part belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series is characterized by its use in microwave and RF applications requiring precise frequency control. Other models in the family offer different frequency ranges but share similar packaging and operational principles. This specific variant targets the 2.3 GHz to 2.45 GHz segment.

Replacement Considerations

Direct substitutes include other Crystek CVCO55BE models with compatible frequency ranges, such as CVCO55BE-2300-2575 or CVCO55BE-2130-2220. Verify that alternative parts match the 5V supply requirement and QFN-16 footprint. Cross-reference tuning voltage ranges and output power levels to ensure functional equivalence in the target application.
