9 0 0 M H Z B I D I R E C T I O N A L A M P L I F I E R T E C H N I C A L M A N U A L 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.
9 0 0 M H Z B I D I R E C T I O N A L A M P L I F I E R T E C H N I C A L M A N U A L Block Diagram Details - The 900 MHz Amplifier module contains a (Low Noise Amplifier) LNA designed to detect a very weak signal. This stage is bypassed if the signal level at the input is higher than -20dBm - The LNA is followed by an Automatic Gain Control (AGC).

A Serial to USB cable is available under request. The software designed for this purpose is provided (ver 1.02). This software should be installed on a computer with Windows, XP,Vista,7, 8 or 10 versions. When you run the software you will see the screen shown below.

Automatic attenuation delivered by the AGC to maintain the output level constant. When this value shows “0” it is because the input power is lower than -53 dBm. If it is zero in the Downlink path the AGC alarm will turn red. 5) DC voltage / current monitor. It shows the DC voltage and current to the RF unit. 6) System temp. Shows the current system temperature. 4.
