High Frequency Surface Mount Terminators RFX Series • • • • RoHS Compliant Frequency operation to 3GHz Small size 10W power chip resistors 1% tolerance and 50ppm/°C absolute TCR The RFX series of high frequency line terminators provide superb high frequency performance at power ratings to 10W in a surface mount chip. Both leadless versions provide maximum flexibility for mechanical circuit attachment and circuit configuration. The RFX is available in a wide range of ohmic values from 50Ω to 800Ω affording maximum flexibility in controlled impedance transmission line design and termination. Applications include RF/microwave power amplifiers, power splitters, cell base stations and circulators/isolators.
