R319Z-SW-QMA-QMA

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 8 Variable Attenuators on a 1RU High Rack or H-Frame. Each Attenuator Module (Model #: 318Z-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 side of the units, so that 4 modules can be mounted on a rack, which makes it easy to plug in the INPUT and OUTPUT on the front. Each attenuator path can handle 5W of power and operates from 600MHz – 4200MHz. The Attenuators come with QMA (F) connectors standard.
