BTR 28-08 GHz MMIC
Quick Reference Guide
Product Overview
The BTR 28-08 GHz MMIC (NTVG14BH) outdoor transceiver is a state-of-theart 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°.
