SMV5550B-LF

Overview

The SMV5550B-LF is a voltage-controlled oscillator (VCO) manufactured by Z-Communications, Inc. It operates within an oscillation frequency range of 5000 to 6000 MHz. The device utilizes a tuning voltage input spanning 0 to 10 Vdc to achieve wideband tuning across this spectrum. Key electrical specifications include a typical second harmonic suppression of -35 dBc and a power output level of ±3 dBm. The component is designed for surface mount integration.

Feature Summary

• Provides wideband frequency tuning capability across the 5000 to 6000 MHz range
• Features low phase noise performance with specified harmonic suppression
• Utilizes a standard 0 to 10 Vdc control voltage interface for frequency adjustment

Applications

• Satellite communication systems
• Fixed wireless access networks
• Microwave test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and manufacturing date code upon ordering. Confirm that the surface mount package style matches the intended PCB footprint and soldering profile requirements. Ensure the supply chain source provides authentic components from Z-Communications, Inc. to guarantee compliance with the published electrical characteristics and reliability standards.

Selection Notes

Select this component when a wide tuning range centered around 5.5 GHz is required in a compact form factor. Consider the ±3 dBm output power and -35 dBc harmonic suppression for system link budget calculations. Evaluate the 0 to 10 Vdc tuning sensitivity against available control circuitry. This VCO is suitable for applications demanding stable microwave frequency generation with minimal external filtering.

Part Context

This part belongs to the SMV series of voltage-controlled oscillators from Z-Communications, Inc., which are designed as surface mount modules. These components are engineered for high-performance RF applications requiring precise frequency control. The SMV5550B-LF specifically targets the C-band and upper microwave frequencies, offering a balance of tuning width and spectral purity for modern communication architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Z-Communications models such as the SMV2200L or CRO2950B-LF only if frequency ranges and pin configurations align, though direct substitution requires independent verification of electrical parameters.
