1.0 GENERAL INFORMATION
1.1 Functional Overview
The Vecima Networks TRI2525B is an outdoor RF transceiver for use in broadband wireless systems.
The TRI2525B combines a low noise downconverter, high power upconverter, antenna and high
rejection duplexer to offer a fully integrated solution for 3.5 GHz subscriber terminals. The TRI2525B
integrated subscriber transceiver serves to frequency translate and amplify the upstream and
downstream signals to the appropriate intermediate frequencies for use by the indoor DOCSIS modem.
The TRI2525B and antenna are situated outdoors and connected to a cable modem indoors by a low
cost 75 ohm cable (i.e. RG-59, RG-6 or similar). A single RF F-connector on the weatherproofed
enclosure provides the interface to the transmit/receive antenna for rapid installation.
