Fixed SMA Attenuators

Molex Fixed SMA Attenuators feature standard frequency values of 18GHz and 23GHz and an average 2W input power. These attenuators include a 250W peak power (5uSec pulse, .05% duty cycle) and 50Ω impedance. The 73287 attenuators are passivated stainless steel SMA Connectors mated with MIL-STD-348 and feature gold-plated Beryllium Copper. These SMA attenuators operate at a -65°C to 125°C temperature range and come in standard values of 0dB to 10dB, 12dB, 15dB, 20dB and 30dB. Typical applications include aerospace and defence devices.
