Powerfilm™ flange attenuators are designed to uniformly reduce power of the RF signal while generating only a small reflection even under maximum power conditions. The flange attenuators are often used in high-power amplifiers and as terminating attenuators in isolators where lower-level signal sampling may be required. Standard dB values are 1, 2, 3, 4, 5, 6, 10, 20, and 30 for frequencies up to 4 GHz and power levels up to 250 Watts. Other designs may be available upon request
