Approval Pending

WaveCom’s TRI5758 is an all-weather transceiver designed for subscriber end-use in a fixed broadband wireless

system. The TRI5758 combines a low noise downconverter, high power upconverter, directional antenna, and high

rejection diplexer to offer a fully integrated RF solution. The TRI5758 transceiver serves to frequency translate and

amplify both Upstream and Downstream signals to the appropriate intermediate frequencies for use by an indoor a

DOCSIS-compliant or similar cable modem. The TRI5758 is intended to be installed outdoors and connected to the

cable modem via low cost 75-ohm coaxial cable such as RG-59, or RG-6. The weatherproof enclosure includes an

external F-connector, and internal signal strength indicating beeper, which allows for easy alignment and

installation of the unit.

• Meets unlicensed-band maximum allowable transmit power of +28 dBm EIRP

• High Receive Gain of 53 dB allows for optimal Downstream signal recovery for high SNR

• Automatic transmitter RF mute when modem is not transmitting

• Low Noise Figure; < 6 dB typical

• Digital temperature compensation to guarantee specifications over full operating range

• All local oscillators are frequency synthesized and locked to a common internal high stability reference

• Integrated planar antenna

• High reliability, state-of-the-art design using microstrip, MMIC and surface mount technology

• Conservative component derating and 100% burn in help ensure reliable operation

• Fully weatherized unit, suited for outdoor mounting

• Audible installation alignment beeper; to facilitate customer self install
