DAS-1819-4009 1900 MHz (PCS + GSM) DAS Conditioning Tray Features • Provides a single connection point for cellular base stations in either AWS or PCS spectrum at either BTS port • Integrated variable step attenuation for each channel • Adjustment range of 30 dB with 1 dB increments • MIMO deployment configuration • Passive DAS assembly without external power requirements • Each BTS port feeds both sectors A & B & both sectors A & B feed each BTS port API's DAS Interface Tray provides a single connection point when using single or multiple base stations by standardizing the connection between the BTS and the DAS head-end equipment and improving the uplink signal with minimal impact to the receive signal. API's low PIM DAS Interface Tray provides integrated variable step attenuation in the Tx (DL) path for each input with an adjustment range of 30 dB with 1 dB increments.
