Overview
The Crystek CRBV55BE-1650-2150 is a Voltage Controlled Oscillator (VCO) operating within the 1650 to 2150 MHz frequency range. It features a center frequency of 1900 MHz and requires a control voltage between 0.5 V and 4.5 V. The output power ranges from 1.58 mW to 6.31 mW, equivalent to approximately 5 ±3 dBm. The device exhibits a typical second harmonic suppression of -15 dBc. It operates across an extended temperature range of -40°C to 85°C and utilizes a RedBox module adapter package with SMA F connectors.
Feature Summary
- Provides stable oscillation in the 1.65 to 2.15 GHz band
- Utilizes RedBox packaging for compact integration
- Supports wide industrial temperature operation
Applications
- Wireless communication systems
- RF signal generation circuits
- Test and measurement equipment
Procurement Notes
Verify the specific part number suffix against official Crystek documentation to ensure correct frequency tuning and pinout configuration. Confirm that the required SMA F connector interface matches the system design requirements. Check for updated revision levels or alternative series members if current availability is constrained. Ensure environmental specifications meet the target application's thermal constraints.
Selection Notes
Select this component when a fixed frequency range of 1650 to 2150 MHz is required. Consider the 0.5 V to 4.5 V control voltage compatibility with existing bias networks. Evaluate the RedBox form factor against available PCB space. Verify that the output power level meets the downstream amplifier or mixer input requirements without excessive gain stages.
Part Context
This model belongs to the Crystek CRBV55 series of Voltage Controlled Oscillators. The series is characterized by its RedBox packaging style, which offers a standardized footprint for RF designs. These components are designed for applications requiring precise frequency control within specific microwave bands.
Replacement Considerations
Consult Crystek official cross-reference lists for direct substitutes. Verify that any replacement maintains the 1650-2150 MHz range and compatible control voltage specifications.
