FM86GM2004

Overview

The FM86GM2004 is a bi-phase modulator manufactured by Fairview Microwave, designed for radar applications. It operates within a frequency range of 4 GHz to 8 GHz and features SMA connectors for interface connectivity. The device utilizes TTL control signals to achieve phase modulation angles ranging from 0 to 180 degrees. A key performance characteristic is its switching speed, specified at 30 nanoseconds, enabling rapid phase state transitions. This component is classified as an active RF module suitable for systems requiring precise phase control in the microwave spectrum.

Feature Summary

• Bi-phase modulation capability with 0 to 180-degree phase shift range
• TTL logic control interface for direct digital driving
• High-speed switching operation with 30 nanosecond transition time
• SMA connector interfaces for standard RF integration

Applications

• Radar system phase control circuits
• Microwave communication link modulation
• Test and measurement instrumentation phase shifting
• Electronic warfare signal processing

Procurement Notes

Verify the specific datasheet version and pinout configuration before integration, as manufacturer documentation may vary between revisions. Confirm that the TTL voltage levels match your system logic standards to ensure reliable switching. Check for any required biasing networks or impedance matching components not included in the module package. Ensure thermal management considerations are addressed if operating continuously near maximum ratings. Validate connector compatibility with existing cable assemblies to maintain signal integrity.

Selection Notes

Select this component when a compact, high-speed bi-phase modulator is required for 4-8 GHz applications. It is appropriate for designs needing direct TTL control without external driver circuitry. Consider the SMA interface requirements and ensure PCB layout supports the necessary trace impedances. Evaluate the 30 ns speed against system timing constraints to confirm suitability for pulse modulation rates. Compare physical dimensions and mounting options against available board space.
