- Test instruments
Procurement Notes
Verify the specific part number against official Crystek documentation to confirm the 1.874 GHz to 2.074 GHz frequency range and 8V supply requirement. Ensure compatibility with the required 31.75 mm x 14.99 mm RedBox package dimensions. Confirm RoHS compliance status and check for any specific revision level updates before procurement.
Selection Notes
Select this VCO when a narrowband frequency range around 1.974 GHz is required with precise voltage control between 0.5 V and 4.5 V. Consider the 8V supply constraint and the specific physical footprint of the RedBox connectorized package. Evaluate the need for low phase noise and harmonic suppression suitable for fixed wireless or test instrument environments.
Part Context
This component belongs to the Crystek RedBox series of Voltage Controlled Oscillators, designed for robust integration into various electronic systems. The series offers connectorized options that simplify assembly compared to surface-mount alternatives. The CRBV55BE-1874-2074 specifically targets applications requiring stable operation within the 1.874 GHz to 2.074 GHz band.
Replacement Considerations
The CRBV55BE-1848-1852 is a documented alternative within the same RedBox series, sharing similar operating temperature ranges but differing in frequency specifications and supply voltage requirements. Verify electrical parameters before substitution.
