Quick Reference Guide
Product Overview
The BTR 28-07 GHz MMIC (NTVG14CA) 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 and 1.3 equipment.

Converted Frequency Formula
Use the following formula to calculate the converted frequency:
TX: ƒRF OUT (GHz) = 28.60 (GHz) + ƒIF INPUT (MHz)
RX: ƒIF OUTPUT (MHz) = 28.60 (GHz) - ƒRF INPUT (GHz)
Note: The antenna has an option of a hydrophobic coating that can help to
reduce ice build-up effect.
Note: Vent holes are covered with a GoretexTM patch.
Note: The transceiver mounts to a vertical pole of 2.5” to 4.5” outside diame-
ter. It has a range of motion of 90° over and -60° under horizon. The bases of
the antenna mount can rotate ±180°.
Note: The module connector is N-Type female. The receive IF input/output
cables present a male N-Type connector. The Tx IF and the Rx IF test ports
are SMA-Type female. The Telemetry port: 6 pin female military-style con-
nector.
