Overview
The CVCO55BE-2130-2220 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, designed for frequency control applications. It operates within a tuning range of 2130 to 2220 MHz, with a center frequency of 2175 MHz. The device requires a control voltage input between 0.5 V and 4.5 V to adjust the output frequency. It features a typical second harmonic suppression of -12 dBc and delivers an output power of 0 ±2 dBm. The component is housed in a compact 16-QFN package measuring 12.7 mm x 12.7 mm with a height of 3.81 mm.
Feature Summary
- Voltage-controlled operation across a defined microwave frequency band
- Integrated harmonic suppression for cleaner signal output
- Compact surface-mount packaging for space-constrained designs
Applications
- Microwave communication systems
- Frequency synthesis circuits
- Test and measurement equipment
Procurement Notes
Verify the specific suffix BE against the official Crystek datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the control voltage range aligns with your system's available supply rails. Confirm the 16-QFN footprint dimensions are compatible with your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a fixed-frequency-range VCO is required for the 2.1 GHz band. Consider the 0.5 V to 4.5 V control voltage window relative to your microcontroller or DAC outputs. Evaluate the 0 ±2 dBm output power level against your downstream amplifier needs. Verify that the QFN thermal pad requirements meet your board's thermal management strategy.
Part Context
This part belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency ranges tailored for different RF applications. The CVCO55BE-2130-2220 specifically targets the 2130-2220 MHz range, distinguishing it from other variants like the CVCO55BE-1750-2150 which covers lower frequencies.
Replacement Considerations
Direct substitutes include other Crystek CVCO55 series models with similar frequency ranges, such as the CVCO55BE-2130-2220 itself if ordering variations exist. Cross-brand replacements require careful verification of pin compatibility, control voltage ranges, and output power levels to ensure functional equivalence.
