CVCO55BE-1950-2070

Overview

The CVCO55BE-1950-2070 is a Voltage Controlled Oscillator (VCO) from the Crystek CVCO55 series, designed for high-frequency applications. It operates within a frequency range of 1950 MHz to 2070 MHz, with a center frequency of approximately 2010 MHz. The device utilizes a tuning voltage range of 0.5 V to 4.5 V and requires a supply voltage of 5.25 V. Key electrical specifications include a typical phase noise of -118 dBc/Hz, second harmonic suppression of -20 dBc, and an output power of -5.0 ±1 dBm. The maximum supply current is 40 mA, with a pushing factor of 0.5 MHz/V. It is housed in a 16-QFN package measuring 12.70mm x 12.70mm x 5.59mm and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• High-frequency capability optimized for demanding RF applications without compromising performance
• Compact surface-mount design suitable for space-constrained PCB layouts
• Stable operation across a wide industrial temperature range

Applications

• Wireless communication systems requiring stable local oscillators
• RF test and measurement equipment
• Satellite communication transceivers

Procurement Notes

Verify the specific suffix and pinout configuration against the official Crystek datasheet before integration. Ensure that the PCB footprint matches the 16-QFN variant dimensions precisely. Confirm thermal management requirements for the specified operating temperature range. Check RoHS3 compliance status if environmental regulations apply to your region. Validate supply voltage stability at 5.25 V to maintain optimal phase noise performance.

Selection Notes

Select this component when a fixed high-frequency VCO is required rather than a tunable range spanning multiple bands. Compare phase noise and harmonic suppression metrics against alternative solutions to ensure signal integrity. Consider the 12.7mm square package size for mechanical clearance. Evaluate the 40mA current draw against available power budgets. Verify compatibility with the 0.5V to 4.5V control voltage interface.

Part Context

This part belongs to the CVCO55 series by Crystek Corporation, which includes various models tailored for different frequency bands such as CVCO55CC and CVCO55BE. The BE designation typically indicates specific resonator or performance characteristics suited for higher frequencies compared to other series variants. This model specifically targets the 2 GHz range, distinguishing it from lower frequency counterparts like the 464.5 MHz CVCO55CC-0444-0485.

Replacement Considerations

Direct substitutes are limited due to specific frequency and package constraints. Cross-reference with other Crystek CVCO55BE models if frequency tolerance allows. No public confirmed substitute part numbers are identified for exact replacement.
