The SALF-78+ is a Low Pass Filter from Mini-Circuits. It is designed to pass signals below a certain cutoff frequency while attenuating signals above that frequency. This particular model is known for its compact size and robust construction.

Applications

• Harmonic Rejection: Used to filter out unwanted harmonics in RF signals.
• Receiver Front-End: Applied at the input of receivers to suppress out-of-band signals.
• Transmitter Output: Employed to clean up the output signal of transmitters.
• General Signal Conditioning: Used to remove unwanted high-frequency noise from signals.

Features

• Low Insertion Loss: Minimizes signal attenuation in the passband.
• High Rejection: Provides significant attenuation of signals above the cutoff frequency.
• Miniature Size: Compact design allows for easy integration into various systems.
• Rugged Construction: Designed to withstand harsh environments.
• Surface Mountable: Facilitates automated assembly.

Benefits

• Improved Signal Quality: Removes unwanted noise and harmonics, resulting in cleaner signals.
• Enhanced Receiver Sensitivity: Suppresses out-of-band signals, improving receiver performance.
• Reduced Interference: Minimizes unwanted signal radiation.
• Easy Integration: Compact size and surface mountable design simplify integration.

Technical Specifications

The SALF-78+ has a passband from DC to 78 MHz. It provides typically 20 dB rejection at 150MHz. The insertion loss in the passband is typically less than 1 dB. The filter utilizes a surface mount package. The impedance is 50 Ohms.
