| High Frequency Surface Mount Attenuators RFAXXX-0 Series * RoHS compliant * Power dissipation up to 150W * High frequency operation up to 3GHz The RFAXXX-0 series power attenuator has a low VSWR from DC to 3GHz. High frequency performance combined with high power dissipation make this an ideal RF power attenuator. Typical applications are RF and microwave power amplifiers, RF transmitters, receivers and meters where a reduction in power is needed while maintaining transmission line characteristic impedances. Electrical Data RFA100-0xx Power Rating @70C Impedance Frequency Range Operating Temperature Range Attenuation Attenuation Tolerance at DC Types 010, 020, 030 Terminations Types 012, 022, 032 Gold (Au) plated copper 100W (Heatsinked) 50 DC - 3GHz -55C to +155C 20dB, 30dB 0.4 dB Tin (Sn) plated copper RFA150-0xx 150W (Heatsinked) General Note IRC reserves the right to make changes in product specification without notice or liability.
