Figure 1. R-tron iDEN Add-On Filter Box
The interference within the service frequency bands is a target to be
removed because it causes the degradation of the service quality and
shrinking of the coverage.
iDEN Add-On Filter Box is the equipment for filtering off such interference
adjacent to iDEN downlink frequencies allocated at 800MHz’s and 900MHz’s
with the following features:
7MHz or 18MHz filtering @ 800MHz’s
5MHz filtering @ 900MHz’s
Band Shifting @ 800MHz’s and 900MHz’s
Roll Offs: 65 dBc at 0.5 MHz outside pass-band
