The HFTC-39+ is a high pass filter manufactured by Mini-Circuits. It is designed to attenuate signals below its cutoff frequency while allowing higher-frequency signals to pass through with minimal insertion loss. This filter is suitable for a wide range of applications where specific frequency bands need to be isolated or removed.

Applications

• Harmonic rejection in transmitters.
• Image rejection in receivers.
• Suppression of unwanted low-frequency noise in RF systems.
• Spectrum cleanup in test and measurement setups.
• Signal conditioning in communication systems.

Features

• High pass filter design: Allows signals above the cutoff frequency to pass through with minimal attenuation.
• Sharp cutoff: Provides rapid attenuation of signals below the cutoff frequency.
• Low insertion loss: Minimizes signal loss in the passband.
• High stopband attenuation: Effectively suppresses unwanted signals in the stopband.
• Rugged construction: Designed to withstand harsh environmental conditions.
• Compact size: Small form factor for easy integration into various systems.

Benefits

• Improved signal quality: Removes unwanted frequencies and noise.
• Enhanced system performance: Reduces interference and spurious signals.
• Increased sensitivity: Improves receiver sensitivity by rejecting out-of-band signals.
• Simplified system design: Provides a convenient solution for frequency selection.
• Reliable operation: Rugged construction ensures stable performance.

Additional Details

The HFTC-39+ has a typical cutoff frequency of 39 MHz. It has a passband insertion loss typically less than 1 dB and a stopband attenuation of greater than 40 dB. The filter operates over a wide temperature range, and its compact size makes it suitable for densely populated circuit boards.
