The M3933/16-42N is a fixed attenuator providing a nominal attenuation of 18 dB. It operates with a 50 Ohm impedance across a frequency range of DC to 18.0 GHz. This device is rated for 2 Watts of average power at 25°C (derating to 0.5 W at 125°C) and can handle a peak power of 500 Watts. It features an attenuation accuracy of ±0.7 dB and a maximum VSWR of 1.35:1 in the 12.4-18 GHz range. Built with a passivated stainless steel body and gold-plated contacts, it is suitable for various RF and microwave applications requiring precise signal level control across a wide temperature range of -55°C to +125°C.
