Rack Mounted Variable Attenuator Tray for DAS Solution

1dB-31dB variations with 1dB Step, 5W, 1RU High, 600-4200MHz

R319H-SW—QMA-QMA is a Rack-mounted DAS Tray solution that holds 4 Variable Attenuators on a 1RU High Rack or H-Frame. Each Attenuator Module (Model #: 318-SW-QMA-QMA) has 2x variable attenuators integrated in one housing, each having its own independent RF path. The attenuation value can be varied from 1 dB to 31 dB, in 1 dB steps. The connectors are on the front of the rack, which makes it easy to plug in the INPUT and OUTPUT on the same side. Each attenuator path can handle 5W of power and operates from 600MHz – 4200MHz. The Attenuators come with QMA (F) connectors standard.
