DAS-8685-4011
SMR 800 DAS Conditioning Tray
2 BTS/6 DAS, with fixed and variable attenuation, UL & DL test ports, MIMO or SISO capable
Features
• This product allows either SISO or MIMO operation to
be selected based upon which ports are terminated.
• Adjustment range of 0 to 30 dB with 1 dB increments.
• Passive DAS assembly without external power
requirements.
• Each downlink (DL) and uplink (UL) is adjustable
without intrusive connections to the system.
• Test or monitor ports are located on the front panel.
API's SMR 800 DAS Interface Tray is designed to manage two SMR800 duplex inputs and provide independent simplex outputs..
Our DAS Interface Tray standardizes the connection between the BTS and the DAS head-end equipment by improving the
uplink signal with minimal impact to the receive signal. API's low PIM DAS Interface Tray also provides integrated variable step
attenuation in the UL and DL paths for each input with an adjustment range of 30 dB in 1 dB increments.
