Inmet Powerfilm Flange Mount Attenuators

Powerfilm Flange Mount Attenuators

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. The attenuators are available in standard dB values of 1, 2, 3, 4, 5, 6, 10, 20 and 30 for frequencies up to 4 GHz and power levels up to 250 Watts. Flange sizes vary from 0.3"x0.2" to 1.25"x0.5". Other designs may be available upon request.
