Overview
The Crystek Corporation CRBV55CL-0902-0928 is a Voltage Controlled Oscillator (VCO) operating within the 902 MHz to 928 MHz frequency range, with a center frequency of 915 MHz. It utilizes a tuning voltage span of 0.5 V to 4.5 V and requires a 5 V supply. The module delivers an output power of ±3 dBm and exhibits a typical second harmonic suppression of -15 dBc. Designed for industrial environments, it functions between -40°C and 85°C. The component features a load capacitance of 100 pF and a maximum current consumption of 20 mA.
Feature Summary
- Provides stable oscillation across the 902-928 MHz ISM band using a single 5V supply.
- Integrates SMA female connectors for direct RF interface connectivity.
- Maintains low phase noise characteristics suitable for precision signal generation.
Applications
- Industrial, Scientific, and Medical (ISM) equipment

- Telemetry systems
Procurement Notes
Verify that the specific part number matches the required 902-928 MHz frequency range and RedBox packaging style. Confirm compatibility with the 0.5-4.5V tuning voltage profile and 5V supply requirement before integration. Ensure environmental ratings meet the -40°C to 85°C operational scope for your specific deployment conditions.
Selection Notes
Select this component when a fixed 915 MHz center frequency with narrow bandwidth is required. It is appropriate for designs needing integrated SMA connectors and robust industrial temperature performance. Consider the ±3 dBm output power and -15 dBc harmonic suppression limits against system link budget requirements.
