CVCO55BE-1930-1990

Overview

The CVCO55BE-1930-1990 is a Voltage Controlled Oscillator (VCO) from the CVCO55 series by Crystek Corporation. It operates within a frequency range of 1.93 GHz to 1.99 GHz, with a center frequency of approximately 1.96 GHz. The device features a tuning voltage range of 0.3 V to 4.7 V and requires a 5 V supply voltage. Key electrical specifications include an output power of -5 dBm ±1 dB, a typical phase noise of -105 dBc/Hz, and a second harmonic suppression of -20 dBc. The maximum supply current is 20 mA, with a pushing factor of 1 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 70°C.

Feature Summary

• Provides stable voltage-controlled oscillation across the 1.93–1.99 GHz band
• Delivers consistent output power with low phase noise characteristics
• Utilizes a compact surface-mount QFN package for efficient PCB integration

Applications

• Wireless communication systems requiring precise frequency synthesis
• Local oscillator stages in RF transceivers
• Test and measurement equipment signal generation

Procurement Notes

Verify that the specific part number matches the required frequency range and package type. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure that the supply voltage and tuning voltage requirements align with your system design before finalizing procurement orders.

Selection Notes

Select this component when a fixed frequency range near 1.96 GHz is required without external tuning components. Consider the -105 dBc/Hz phase noise specification for applications sensitive to spectral purity. Evaluate the 20 mA current consumption against power budget constraints and verify thermal management capabilities for the specified operating temperature range.

Part Context

This model belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency bands tailored for different RF applications. The CVCO55BE-1930-1990 specifically targets the UHF/SHF transition region, providing a ready-to-use solution for designers needing a compact, high-performance oscillator source.

Replacement Considerations

Check Crystek datasheets for other CVCO55 variants with compatible frequency ranges. Verify pinout compatibility and electrical parameters such as phase noise and output power when considering alternative models from the same manufacturer or competitors.
