Based on the philosophy of Anytime, Anywhere, and Anyplace, the 896-940 MHz amplifier module
is designed for ease of use to be adaptable to various needs in the field. Recently developed
technologies are applied. With the use of modern integrated circuits and RF components, the
Comprod design ensures constant performance and a reliable amplifier unit.
The 900 MHz amplifier has also been designed with government agencies in mind. These agencies
require the highest level of performance and quality for continuous duty solutions while providing
maximum coverage. This amplifier module is aimed for the use in buildings, tunnels, government
facilities, airports, providing the required communication throughout.
The amplifier module helps to increase the coverage of RF communications in buildings or places
where RF is unable to penetrate from the base station site. The Amplifier Module can be used in both
Uplink and Downlink directions and it is connected to either a radiant cable, or a distributed antenna
system at one end. At the other end it’s connected to the donor antenna.
