1500W Harmonic Absorbing Filter

Lebih Lengkap Mengenai 1500W Harmonic Absorbing Filter

All RF amplifiers will "react" in some way when a low pass filter is attached. This reaction is mainly caused by reflected harmonics. All RF amplifers generate harmonics. When a low pass filter is attached to the amplifer most of the harmonic energy is reflected back to the transistor causing reduced efficency and output power. The transistor will also run hotter.

This filter terminates all harmonics up to 550MHz with a 50 ohm 250W termination. This filter will improve the performance of all FM amplifiers.

This low pass filter is designed for use with any FM pallet amplifier operating up to 1500W.
