Overview
The CRBV55BE-1848-1852 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, designed for RF applications. It operates with a center frequency of 1850 MHz and covers a tuning range from 1848 MHz to 1852 MHz. The device requires a supply voltage of 8 V and accepts a tuning voltage between 0.5 V and 2 V DC. Typical output power is specified at 6 ±2 dBm, while the maximum supply current is 35 mA. Harmonic performance includes a typical second harmonic level of -15 dBc, and phase noise is typically -106 dBc/Hz.
Feature Summary
- Voltage-controlled operation with defined tuning voltage range
- Fixed center frequency design for specific RF bands
- Integrated module adapter package with SMA connectors
Applications
- RF signal generation in communication systems
- Local oscillator sources in receiver architectures
- Test and measurement equipment requiring stable frequency synthesis
Procurement Notes
Verify the manufacturer part number against official Crystek documentation to ensure authenticity. Confirm that the received component matches the specified 8 V supply requirement and 0.5 V to 2 V tuning voltage range. Check for physical integrity of the SMA female connectors on the module adapter. Ensure storage conditions comply with standard electronic component handling guidelines to prevent damage to the sensitive RF circuitry within the enclosure.
Selection Notes
Select this component when a fixed center frequency near 1850 MHz is required with narrow tuning bandwidth. Consider the 8 V supply requirement as it differs from common 3.3 V or 5 V logic levels. Evaluate the 6 dBm output power against system loss budgets. The module form factor with SMA connectors simplifies integration into test setups or modular RF designs compared to bare die solutions.
Part Context
This part belongs to Crystek's CRBV series of voltage-controlled oscillators. These components are engineered for stability and performance in microwave frequencies. The specific model integrates the oscillator circuit and tuning control into a shielded metal enclosure, providing electromagnetic interference protection and consistent electrical characteristics across manufacturing batches.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1850 MHz center frequency, 8 V supply voltage, and SMA connector configuration. Verify pinout compatibility and thermal requirements before considering alternative manufacturers.
