Product Overview
The CTR 28-08 MMIC (NTVG16BH) outdoor transceiver is a customer premise
transceiver designed to operate in various Receiver (Rx) and Transmitter (Tx)
frequency bands. It is a Nortel Networks Reunion product that operates in con-
junction with base station products, as well as customer premise products. 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) = ƒIF IN (GHz) + 27.35
RX: ƒIF OUT (GHz) = ƒRF IN (GHz) - 27.35
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 diame-
ter. It has a range of motion of 90° over and -60° under horizon. The bases of
the antenna mount can rotate ±180°.
