High Power Mechanically Tuned Filters

Product Features

• High Power Handling: Specifically designed to process high levels of RF power, capable of withstanding Continuous Wave (CW) and pulsed power, making them suitable for high-power transmit systems.
• Mechanically Tunable Frequency: Achieves precise tuning of the center frequency over a certain range by mechanically adjusting the dimensions or coupling of the resonant cavities (typically via screws or knobs).
• High Q-factor, Low Insertion Loss: Combining cavity or waveguide structures, these filters provide a very high Q-factor, ensuring extremely low in-band insertion loss and maximizing system efficiency.
• Steep Out-of-Band Rejection: Possesses excellent out-of-band rejection capabilities, effectively filtering out unwanted frequency components and offering high selectivity.
• Excellent In-Band Flatness: Maintains good flatness of the signal response within the passband, ensuring distortion-free signal transmission.
• High Reliability: Utilizes robust mechanical structures and materials, ensuring long-term stable and reliable operation in harsh environments.
• Good Frequency Stability: Once tuned, the mechanical locking mechanism and stable cavity design provide excellent frequency stability.
• Highly Customizable: Filter parameters (such as tuning range, bandwidth, order, power handling capacity, connector type, etc.) can be flexibly designed and customized according to specific application requirements.

Applications
