Flange optical attenuator model

Flange optical attenuators are available in various models offering 1–30 dB attenuation, high power handling, and customizable configurations for RF and optical applications.Overview of Flanged Attenuator ModelsFlanged attenuators are designed to reduce signal power while maintaining low reflection and high reliability. They are commonly used in high-power amplifiers, isolators, and RF/microwave systems. Key models and specifications include:Barry Industries Flanged Attenuators: Standard models offer 2–30 dB attenuation for AlN and 0–30 dB for BeO types, with power ratings assuming a flange temperature of 100°C. Custom designs are available for higher power (>250 W) or special attenuation values, with mechanical tolerances of ±0.010" and Copper Tungsten mounting flanges for pulsed power applications .Spectrum Control Flange Mount SMT Attenuators: These attenuators handle frequencies up to 4 GHz and power levels up to 250 W, designed to minimize reflection. They are suitable for terminating attenuators in isolators or sampling lower-level signals. Custom designs are available based on specific requirements .KYOCERA AVX FA Series: High-power flange mount attenuators offering 1–30 dB attenuation, frequency range up to 3 GHz, and power handling up to 150 W. Manufactured in ISO 9001 facilities, these are suitable for high-reliability applications .Preferred Power Products HYBR-FILM™ Flanged Attenuators: High-performance RF and microwave resistive attenuators with standard power ratings up to 150 W, designed for solder or bolt-down flange mounting. Applications include medical, broadcast, industrial, military, and space systems. Custom modifications and higher power levels are available upon request .Allaway Acoustics Rectangular Flanged Models (SP/SL): These attenuators are constructed from pre-galvanized or stainless steel, with options for high temperature or high-pressure applications. Flange sizes typically 20–30 mm, with modular construction available. Insertion loss, pressure loss, and flow noise are tested according to ISO 7235 .Key ConsiderationsWhen selecting a flange optical attenuator model, consider:Attenuation range: 1–30 dB depending on model and material.Power handling: 150–250 W standard, higher available on request.Frequency range: Up to 3–4 GHz for RF applications.Mounting type: Flange mount, bolt-down, or solder attachment.Material and construction: AlN, BeO, Copper Tungsten, stainless steel, or modular designs.Customizability: Many manufacturers offer custom attenuation values, power ratings, and mechanical configurations. These models are widely used in military, aerospace, medical, broadcast, and industrial applications, providing reliable performance under high thermal and pulsed power conditions. Contacting manufacturers directly is recommended for custom specifications or higher power requirements.
