High Frequency Surface Mount Terminator RFTF Series • Low return loss • High power dissipation up to 250W • Long life, temperature stable thin film technology IRC’s RFTF series utilizes the combined benefits flange cooling and the high thermal conductivity of aluminum nitride (AIN) to provide power ratings from 10W to 250W. This series comes with single-sided or double-sided flanges and single leaded terminal configurations, adding increased RF design flexibility. Typical applications for the RFTF series include aerospace, wireless communication, satellites, RF power sources and power amplifiers.
