Antennas-Amplifiers HF 2500W High Pass Filters

Antennas-Amplifiers HF 2500W High Pass Filters are passive RF devices designed to pass signals above a defined cutoff frequency while rejecting unwanted lower-frequency signals. It is intended for use in environments where suppression of low-frequency interference is required, such as from low frequency (LF) transmitters (30–300 kHz) or medium wave AM broadcast stations (526.5–1450 kHz). These filters are particularly effective in mitigating interference from these sources. An optional notch filter can be implemented to target and further suppress specific AM broadcast frequencies. Measured data for these 5720 High Pass Filters was obtained using a fully calibrated HP8753ES 2-port network analyzer. These excellent results were achieved by careful selection of components and design.
