FM8253A

Overview

The FM8253A is a signal conditioning component manufactured by Fairview Microwave, classified as an SMA variable phase shifter. It operates within a frequency range of 18 GHz to 26.5 GHz and provides an adjustable phase range with a minimum span of 360 degrees. The device utilizes SMA connectors for interface connectivity, supporting high-frequency signal processing applications requiring precise phase control in microwave systems.

Feature Summary

• Provides continuous phase adjustment capability across the operational bandwidth
• Supports full 360-degree minimum phase rotation range for flexible signal alignment
• Engineered for stable performance in high-frequency microwave environments

Applications

• Phased array antenna beam steering systems
• Microwave test and measurement instrumentation
• Radar signal processing circuits

Procurement Notes

Verify the specific SMA connector gender and mating interface requirements against your system design before ordering. Confirm that the 18 GHz to 26.5 GHz operating range aligns with your application's frequency specifications. Ensure mechanical mounting constraints are compatible with the component's physical dimensions. Request the official datasheet for detailed electrical parameters and thermal management guidelines prior to finalizing procurement decisions.

Selection Notes

Select this component when a wideband variable phase shift is required between 18 GHz and 26.5 GHz. The SMA interface offers standard compatibility for many high-frequency setups. Consider the 360-degree adjustment range if complete phase cycle coverage is necessary for your calibration or beamforming needs. Evaluate thermal dissipation requirements if the device will operate continuously at maximum phase shifts.

Part Context

This part belongs to Fairview Microwave's signal conditioning portfolio, specifically designed for high-frequency phase manipulation. It complements their broader range of RF interconnects and passive components. The FM8253A addresses the need for tunable phase elements in advanced microwave architectures where fixed-phase solutions lack sufficient flexibility for dynamic system adjustments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing SMA interfaces if considering alternative manufacturers. Check if other Fairview Microwave models offer similar frequency ranges but different phase adjustment mechanisms.
