Antennas-Amplifiers 12M High Power Band Pass Filters

Antennas-Amplifiers 12M High Power Band Pass Filters cover the 24.890-24.990MHz frequency range, with power handling capabilities up to 2,000W PEP. They are perfect for multi-station environments like special events, field days and portable operation to protect receivers from excessively strong out-of-band signals. The ATF-5580 is ideal for both reception and transmission and is designed to have an extremely insertion low loss of less than 0.4 dB from 24.890-24.990MHz and significantly suppresses out-of-band interference. All Measurements on the assembled filters were performed with a full 2-port calibrated HP8753ES network analyzer. The ATF-5580 Band Pass Filters are engineered with an advanced filter design, enclosed in a robust powder-coated aluminum enclosure. They are equipped with silver-plated SO-239 connectors, ensuring exceptionally low insertion loss, minimal SWR, and high attenuation of out-of-band signals across the entire 12M band.
