1.0 GENERAL INFORMATION

1.1 Functional Overview

The VCom TRI1819 is an outdoor RF transceiver for use in broadband wireless systems. The TRI1819 combines a

low noise downconverter, high power upconverter, antenna and high rejection duplexer to offer a fully integrated

solution for 1.9 GHz subscriber terminals. The TRI1819 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 TRI1819 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.
