2.2.2 Downlink/ Uplink Path
GRS-1915D-SPR improves and strengthens signals in PCS 1900MHz band.
In downlink path, received from Donor Antenna signal is transferred through Duplexer (DPX)
and Down Conversion (DNC) module, and after choosing one of 5MHz, 10MHz or 15MHz in IF
path the signal is forwarded to Up Conversion (UPC) module. Then, improved signal is sent to
Service Antenna through Diplexer (DPX).
Uplink path is vice versa to Downlink path.
