Quick Reference Guide

Product Overview

The BTR 28-08 GHz MMIC (NTVG14BH) outdoor transceiver is a state-of-the-

art broadband microwave transceiver designed to operate at various frequency

bands downstream. It is a combined broadband transmitter and receiver deployed

in Nortel Networks Reunion point-to-multipoint system. It is compatible with

Reunion’s Release 1.2, 1.3 and 1.4 equipment.

Converted Frequency Formula Use the following formula to calculate the converted frequency: TX: ƒRF OUT (GHz) = 28.15 - ƒIF IN (GHz) RX: ƒIF OUT (GHz) = 28.15 - ƒRF IN (GHz) Note: Electrostatic deposition powder coat, scratch free. Note: Vent holes are covered with a GoretexTM patch. Note: The transceiver mounts to a vertical pole of 2.5” to 4.5” outside diameter. It has a range of motion of 90° over and -60° under horizon. The bases of the antenna mount can rotate ±180°.
