CVCO55BE-3100-3350

Overview

The CVCO55BE-3100-3350 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, designed for microwave applications. It operates within a frequency range of 3100 MHz to 3350 MHz and utilizes a QFN-16 surface-mount package measuring 12.70 x 12.70 mm with a height of 3.81 mm. The device requires a 5.0 V supply voltage and draws a typical operating current of 40 mA. Key electrical specifications include a tuning slope of 40 MHz/V, a tuning voltage range of 0.3 V to 4.7 V, and an output power of 4.0 ± 4.0 dBm. Phase noise is specified at -98 dBc/Hz at 10 kHz offset, with a secondary harmonic level of -30 dBc. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides precise frequency control via analog voltage input within the 3100–3350 MHz band
• Delivers stable RF output power suitable for direct integration into transmitter chains
• Features low phase noise performance critical for high-fidelity signal generation
• Utilizes compact lead-free QFN packaging for automated surface-mount assembly

Applications

• Wireless communication systems requiring frequency synthesis
• Radar transceivers needing stable local oscillators
• Test and measurement equipment for signal analysis
• Satellite communication ground stations

Procurement Notes

Verify that the specific part number matches the required frequency range of 3100 MHz to 3350 MHz, as the CVCO55BE series contains multiple variants with different tuning ranges. Confirm compatibility with the 5.0 V supply requirement and ensure the QFN-16 footprint aligns with the PCB layout. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Validate that the operating temperature range meets the thermal requirements of the intended environment.

Selection Notes

Select this component when a fixed frequency range of 3100–3350 MHz is required rather than a broader tunable range. Ensure the design can accommodate the 0.3 V to 4.7 V tuning voltage swing without exceeding supply limits. Consider the -30 dBc secondary harmonic level in filter design stages. The 40 MHz/V tuning slope dictates the linearity requirements of the control circuitry. Verify that the 4.0 ± 4.0 dBm output power fits the gain budget of the subsequent amplifier stage.

Part Context

This model belongs to the CVCO55BE family of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency bands tailored for microwave applications. The BE suffix typically denotes specific package and performance characteristics within the lineup. This particular variant targets the C-band or lower Ku-band spectrum, providing a balance between phase noise performance and output power for integrated RF front-end designs.

Replacement Considerations

Direct replacements must match the 3100–3350 MHz frequency range and QFN-16 package. Cross-reference with other Crystek models like CVCO55CCQ or CRBV55BE series only if they explicitly support the same frequency band and pinout. Verify that substitute components meet the -98 dBc/Hz phase noise specification and 5.0 V supply requirement to maintain system performance.
