CVCO55BE-1750-1810

Overview

The CVCO55BE-1750-1810 is a voltage-controlled oscillator from Crystek Corporation designed for microwave applications. It operates within a frequency range of 1.75 GHz to 1.81 GHz, with a center frequency of 1.78 GHz. The device utilizes a tuning voltage range of 0.5 V to 4.5 V and requires a supply voltage of 5.25 V minimum. It features a typical phase noise of -118 dBc/Hz and delivers an output power of -5.0 ±1 dBm. The second harmonic is typically suppressed by -15 dBc. The component is housed in a 16-QFN package variant with dimensions of 12.7mm x 12.7mm.

Feature Summary

• Provides stable voltage-controlled oscillation in the 1.75 GHz to 1.81 GHz microwave band
• Delivers consistent output power with specified harmonic suppression characteristics
• Utilizes a compact 16-QFN surface-mount package for efficient PCB integration

Applications

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

Procurement Notes

Verify the specific suffix BE against the official Crystek datasheet to confirm the exact frequency range and electrical specifications. Ensure the design-in process accounts for the minimum 5.25 V supply requirement and the 16-QFN thermal pad soldering guidelines. Cross-reference the part number with the manufacturer's current product status to confirm active availability and RoHS compliance before finalizing procurement plans.

Selection Notes

Select this component when a fixed frequency range near 1.78 GHz is required with precise voltage control. Consider the -15 dBc typical second harmonic suppression for signal purity needs. Evaluate the 16-QFN footprint compatibility with existing board layouts. Compare phase noise performance against system requirements to ensure adequate signal integrity for the intended application environment.

Part Context

This model belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series is characterized by its use in high-frequency applications requiring stable output. The BE suffix denotes specific performance parameters distinct from other variants in the lineup, such as different frequency ranges or package options found in related models like CVCO55CC.

Replacement Considerations

Direct substitutes include CVCO55BE-1750-1810 equivalents if available. Other Crystek models like CVCO55BE-1760-1940 offer similar functionality but with different frequency ranges. Verify pinout and electrical compatibility before swapping.
