CVCO55BE-1400-1624

Overview

The CVCO55BE-1400-1624 is a voltage-controlled oscillator (VCO) from the Crystek CVCO55 series, designed for microwave frequency applications. It operates within a tuning range of 1400 to 1624 MHz, with a center frequency of 1512 MHz. The device requires a 5V supply and accepts a tuning voltage between 0.3 V and 4.7 V. It delivers an output power of -15 dBm typical for the second harmonic and draws a maximum current of 40 mA. Housed in a 16-QFN package measuring 12.70mm x 12.70mm, it functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides precise voltage-controlled frequency generation within the 1.4 GHz to 1.624 GHz band
• Utilizes a compact 16-QFN surface-mount package for efficient PCB integration
• Operates on a standard 5V DC supply with low current consumption
• Maintains stable performance across industrial temperature ranges

Applications

• Microwave communication systems requiring local oscillation
• Test and measurement equipment signal generation
• Radar system frequency synthesis
• Wireless infrastructure upconversion and downconversion stages

Procurement Notes

Verify component authenticity through authorized Crystek distributors or direct manufacturer channels. Confirm that the received part matches the specific model number and packaging format. Check datasheet specifications against application requirements to ensure compatibility with supply voltage and tuning characteristics. Ensure proper handling procedures are followed due to moisture sensitivity levels associated with QFN packages.

Selection Notes

Select this component when a fixed frequency range around 1.5 GHz is required without external tuning circuitry complexity. Consider the 16-QFN footprint for space-constrained designs. Evaluate thermal management needs given the operating temperature range. Compare output power and phase noise requirements against other VCO families if higher performance metrics are necessary for the specific RF chain design.

Part Context

This part belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency bands tailored for different microwave applications. The CVCO55BE variant specifically targets the 1.4–1.6 GHz range, providing a standardized solution for engineers needing reliable frequency sources in compact form factors within the broader portfolio of Crystek's frequency control products.

Replacement Considerations

Direct substitutes may include other Crystek CVCO55 models with compatible pinouts but different frequency ranges, such as CVCO55CC-0444-0485 for lower frequencies. Cross-referencing with other manufacturers' VCOs requires careful verification of pin configuration, supply voltage, and tuning voltage ranges to ensure functional equivalence without redesigning the host circuit.
