CRBV55BE-1000-2000

Overview

The CRBV55BE-1000-2000 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation, designed for microwave frequency generation. It operates within a tuning range of 1000 MHz to 2000 MHz, with a center frequency specified at 1500 MHz. The device requires a supply voltage of 10 V and accepts a tuning voltage input between 1 V and 20 V DC. Maximum continuous current consumption is limited to 25 mA. Output power is rated at 5.5 dBm with a tolerance of ±2.5 dBm. Typical phase noise performance is -100 dBc/Hz, while the second harmonic is typically -10 dBc. The component functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Voltage-controlled operation enabling frequency adjustment via external DC bias
• Integrated module adapter package with SMA female connector interface
• Wide tuning bandwidth covering 1 GHz to 2 GHz spectrum
• Industrial temperature rating suitable for harsh environmental conditions

Applications

• Microwave signal generation in communication systems
• Frequency synthesis circuits requiring wide tuning ranges
• Test and measurement equipment local oscillators
• Radar system transmitter modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct pinout and electrical specifications match the design requirements. Confirm that the SMA female connector orientation aligns with the PCB layout constraints. Check for any recent revisions to the datasheet that may affect mechanical dimensions or thermal characteristics. Ensure the supply voltage regulation meets the 10 V requirement to maintain stable oscillator performance. Validate that the tuning voltage source can provide the necessary 1 V to 20 V range without exceeding the maximum current limits.

Selection Notes

Select this component when a wide frequency tuning range from 1000 MHz to 2000 MHz is required in a compact module format. Consider the 10 V supply requirement and 25 mA current draw for power budget calculations. Evaluate the -100 dBc/Hz phase noise specification against system sensitivity requirements. The industrial temperature range makes it suitable for applications outside standard commercial limits. Ensure the output power level of approximately 5.5 dBm is sufficient for downstream circuitry without additional amplification.

Part Context

This part belongs to Crystek Corporation's CRBV series of Voltage Controlled Oscillators. These components are designed as self-contained modules, simplifying integration into RF designs compared to discrete oscillator circuits. The series offers various frequency ranges, with this specific model targeting the 1-2 GHz band. The use of a module adapter package reduces parasitic effects and improves consistency compared to bare die solutions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 1000-2000 MHz tuning range, 10 V supply, and SMA connector type. Verify compatibility with existing control voltage profiles and thermal management strategies before attempting substitution.
