Hirose's AT-100 V series is a family of DC to 18 GHz SMA in-line (plug-jack) attenuators, available in 1 dB steps from 1 dB to 20 dB. This series has a highly reliable physical structure that makes it suitable for a wide variety of applications such as experimental use in laboratories and mass production facilities. Rather than solid soldering, spring connections are applied between contacts and the resistive substrate, providing stable, high frequency characteristics in environments with varying temperatures, vibrations, and shocks. External surfaces are clad in stainless steel and highly durable and anti-corrosive gold plating is applied on the contact areas. Proving its robustness and high reliability the AT-100 V series fully conforms to the MIL standard (MIL-STD-202) and is RoHS-compliant as well.
