Fixed attenuator

Fixed coaxial microwave attenuator designed to provide stable signal attenuation across a frequency range of DC to 8 GHz. It has a 50-ohm impedance, SMA connectors, and a maximum VSWR of 1.25:1. Attenuation is available from 1 to 60 dB, with custom values available on request. The unit is rated for 2 W average input power at 25 °C and can handle peak power up to 200 W under specified pulsed conditions: 5 μs pulse duration and 0.5% duty cycle. Its temperature coefficient is less than 0.0004 dB/°C, and its insulation resistance is at least 5000 MΩ. It is suitable for protecting test equipment, calibrating RF and microwave systems, matching signal levels, and laboratory or production testing.
