Overview
The CVCO55BE-2400-2650 is a voltage-controlled oscillator from Crystek Corporation operating within the 2.4 to 2.65 GHz frequency range. It requires a 5 V supply and draws a maximum current of 33 mA. The device features a tuning sensitivity of 45 MHz/V with a control voltage range of 0.0 to 3.3 V. Typical phase noise performance is -110 dBc/Hz at a 10 kHz offset, while secondary harmonic suppression reaches -15 dBc. Designed for surface-mount installation, it utilizes a QFN-16 package.
Feature Summary
- Operates as a voltage-controlled oscillator in the 2.4 to 2.65 GHz microwave band
- Provides low phase noise characteristics suitable for precision signal generation
- Utilizes a compact QFN-16 surface-mount package for efficient board integration
Applications
- Wireless communication systems requiring stable microwave sources
- Test and measurement equipment needing precise frequency synthesis
- Satellite navigation receivers demanding low-noise local oscillators
Procurement Notes
Verify that the specific part number matches the required frequency range and package type. Confirm supply voltage requirements align with system design constraints. Ensure compatibility with recommended bypass capacitors and low-noise regulators as specified in official documentation. Check for any specific ordering suffixes that may alter electrical characteristics or packaging configurations before finalizing procurement orders.
Selection Notes
Select this component when a wide tuning range and low phase noise are critical for microwave applications. Consider the 5 V supply requirement and 33 mA current draw during power budget calculations. Evaluate the QFN-16 footprint against available PCB space. Compare tuning sensitivity and harmonic suppression against alternative models if strict spectral purity or specific voltage ranges are necessary for the target application.
Part Context
This model belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency options tailored for different microwave bands. The BE variant typically denotes specific package and performance characteristics within the lineup. These components are designed to provide reliable frequency generation for high-performance electronic systems requiring stable and tunable microwave signals.
Replacement Considerations
Direct substitutes include other Crystek CVCO55 series variants such as CVCO55BE-2900-3100 or CVCO55CCQ-1700-1700, provided the frequency range and pinout compatibility match the design requirements. Verify that alternative parts meet the same phase noise and supply voltage specifications to ensure seamless integration without circuit modification.
