Overview
The CRBV55BE-1658-1662 is a voltage-controlled oscillator manufactured by Crystek Corporation. It operates within a center frequency range of 1658 MHz to 1662 MHz, with a typical output power of 3 dBm. The device utilizes a tuning voltage range from 0.5 VDC to 2 VDC for frequency adjustment. Key performance specifications include a phase noise level of -106 dBc/Hz and a second harmonic suppression of approximately -15 dBc. The component is housed in a Red Box package.
Feature Summary
- Provides voltage-controlled frequency adjustment over a narrow band
- Delivers stable RF output with specified phase noise characteristics
- Designed for integration into RF signal generation circuits
Applications
- RF communication systems requiring tunable local oscillators
- Test and measurement equipment signal sources
- Wireless infrastructure components
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's current datasheet to ensure compatibility with system requirements. Confirm that the tuning voltage range and output power specifications align with the design constraints before finalizing procurement orders.
Selection Notes
Select this component when a narrow-band tunable oscillator is required around the 1.66 GHz region. Ensure the application can accommodate the specified tuning voltage range and that the phase noise performance meets the system's spectral purity requirements compared to fixed-frequency alternatives.
Part Context
This part belongs to Crystek's Voltage Controlled Oscillator (VCO) product line. Unlike fixed-frequency crystal oscillators, this model offers adjustable frequency output within a defined range. It serves as a critical active component for generating precise RF signals in electronic systems requiring frequency agility.
Replacement Considerations
Consult official substitution lists for compatible VCOs with matching frequency ranges and pin configurations. Verify electrical parameters such as tuning sensitivity and output power when evaluating alternative manufacturers or updated series revisions.
