DAS-1721-4012 Low PIM AWS/PCS DAS Interface Tray 2 BTS/6 DAS, with fixed and variable attenuation, UL & DL test ports, MIMO and 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 low PIM AWS/PCS DAS Interface Tray is designed to manage two BTS 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.
