Overview
The CVCO55CC-1845-1855 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation, designed for microwave frequency control applications. It operates within a frequency range of 1.845 GHz to 1.855 GHz and utilizes a coaxial resonator architecture. The device supports a supply voltage of 5V and functions reliably across an industrial temperature range of -30°C to +70°C. Key electrical specifications include a typical load capacitance of 50 pF, a maximum supply current of 20mA, and an output power of 2.5 dBm with a tolerance of ±2.5 dB. The component is housed in a 16-QFN package with a height of 0.220 inches (5.59mm).
Feature Summary
- Utilizes a coaxial resonator design for stable oscillator performance.
- Operates on a standard 5V supply voltage.
- Provides defined output power levels suitable for RF signal generation.
- Compatible with industrial temperature environments.
Applications
- Microwave frequency synthesis systems
- RF signal generation circuits
- Frequency control modules
Procurement Notes
Verify the specific part number against official Crystek Corporation documentation to ensure accuracy regarding the 16-QFN package and coaxial resonator type. Confirm that the required operating temperature range of -30°C to +70°C aligns with your system's environmental constraints. Ensure compatibility with the specified 5V supply voltage and 50 pF load capacitance requirements before integration into the final design.
Selection Notes
Select this VCO when a narrow frequency band between 1.845 GHz and 1.855 GHz is required. The choice is appropriate for designs needing a 5V supply and robust industrial temperature stability. Consider the 16-QFN form factor for space-constrained PCB layouts. Verify that the 2.5 dBm output power meets the downstream circuit input requirements without additional amplification.
Part Context
This component belongs to the CVCO55CC series of Voltage Controlled Oscillators from Crystek Corporation. The series includes various models covering different frequency ranges, such as the CVCO55CC-1830-1890. Crystek manufactures these devices using quartz-based resonators under their Crystek Microwave division, which specializes in frequency control products for the microwave industry.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Crystek Corporation resources or authorized distributors for potential cross-reference alternatives if this specific model is unavailable.
