CRBV55CL-0434-0452

Overview

The Crystek CRBV55CL-0434-0452 is a crystal filter designed for intermediate frequency (IF) applications. It operates within a center frequency range of 434 MHz to 452 MHz, providing precise signal filtering capabilities essential for communication systems requiring high selectivity and stability. The component utilizes quartz crystal technology to achieve narrow bandwidth performance, ensuring effective rejection of adjacent channel interference while maintaining low insertion loss in the passband.

Feature Summary

• Utilizes quartz crystal resonator technology for stable frequency response
• Designed for intermediate frequency signal processing applications
• Provides high selectivity with narrow bandwidth characteristics
• Ensures effective adjacent channel interference rejection

Applications

• Communication system intermediate frequency stages
• Radio receiver signal filtering
• Test and measurement equipment IF sections
• Professional audio or data transmission filters

Procurement Notes

Verify the specific center frequency and bandwidth requirements against the official datasheet before procurement. Confirm that the package type matches the PCB layout constraints. Ensure environmental operating conditions align with the specified temperature range. Cross-reference the manufacturer's latest documentation to confirm current availability and compliance status.

Selection Notes

Select this component when narrow bandwidth filtering at VHF frequencies is required. Consider the physical size constraints and mounting style compatibility with the target assembly. Evaluate thermal management needs if the application involves high power levels. Compare alternative models only if specific electrical parameters differ significantly from project requirements.

Part Context

This part belongs to Crystek Corporation's line of crystal filters, which are specialized passive components used in RF and IF circuits. These filters are distinct from general-purpose crystals as they offer defined bandwidths rather than single-frequency resonance. They are commonly integrated into transceivers and receivers where channel separation is critical.

Replacement Considerations

Direct substitutes must match the center frequency, bandwidth, and impedance specifications exactly. Verify pinout compatibility and mechanical dimensions before substitution. Consult the manufacturer's cross-reference guide for approved alternatives. Generic replacements may not provide identical phase linearity or stopband attenuation characteristics.
