Overview
The CRBV55BE-2560-2920 is a voltage-controlled oscillator manufactured by Crystek Corporation, operating within the 2.56 GHz to 2.92 GHz frequency range with a center frequency of 2740 MHz. It requires an 8 V supply voltage and accepts a tuning voltage input between 0 VDC and 18 VDC. The device delivers a typical output power of 0 dBm (1 mW) and exhibits a second harmonic level of -10 dBc. Maximum current consumption is specified at 35 mA, with a pushing factor of 0.5 MHz/V.
Feature Summary
- Voltage-controlled operation across a defined microwave frequency band
- Integrated RedBox package design for compact integration
- Standard DC tuning voltage interface for frequency modulation
Applications
- Microwave signal generation in communication systems
- Frequency synthesis modules
- Test and measurement equipment local oscillators
Procurement Notes
Verify the specific ordering suffix against official Crystek documentation to ensure correct package variant and environmental rating. Confirm that the required tuning voltage range aligns with system control circuitry capabilities. Check RoHS compliance status if restricted substances are mandated. Ensure supply voltage stability meets the 8V requirement to maintain specified performance parameters.
Selection Notes
Select this component when a fixed-frequency-range VCO with moderate output power is required. The 0-18V tuning range offers broad frequency coverage within the 2.56-2.92 GHz band. Consider the 35mA maximum current draw for power budget calculations. The RedBox form factor suits applications with strict spatial constraints compared to larger ceramic packages.
Part Context
This part belongs to the Crystek CRBV55 series, which utilizes a RedBox package style. This series provides voltage-controlled oscillators designed for general-purpose microwave applications. The CRBV55BE-2560-2920 represents a specific frequency configuration within this family, offering a center frequency of 2740 MHz.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching frequency range, tuning voltage, and package dimensions with other manufacturers' VCO offerings.
