KA-6020

TWIN 700/800/900 OUT OF BAND EMISSION FILTER (PROTECT GSM-R DL BAND)

The KA-6020 is ideal for co-located 700/800/900 and GSM-R networks. This filter is to be used on the commercial 700/800/900 BTS side to protect the GSM-R network from wideband interference. Utilising a 5MHz guardband the KA-6020 provides rejection of out of band emission into GSM-R band while passing 700, 800 & 900 UL and DL bands. Capable of being used in an outdoor environment the KA-6020 contains two identical bandstop filters, suitable for 2x2 MIMO configuration, offering excellent insertion loss, group delay, EVM and rejection.

FEATURES

  • Rejection of out of band emissions into GSM-R downlink
