To ensure effective VHF/UHF Satellite communications, a number of variables must be considered. Providing superior up and downlink performance, as well as properly setting up the Receive path to maximise the link quality and reliability, are two key factors.

In response to these requirements, AR Modular has developed the RF Model AR-50 Booster Amplifier, which automatically detects and switches between Transmit and Receive paths with no operator intervention required.

For the Receive path, two modes are available: LNA-OFF and LNA-ON. The mode is selected using the Control Knob on the front panel of the Amplifier.

The following plots illustrate typical AR-50 receiver performance over a sample of three units operating in the LNA-On Mode. The plots show a consistent gain and flatness performance between Amplifiers with superior out of band rejection.

Marker 1 247.5MHz, 12.73dBm

Marker 1 247.5MHz, 13.305dBm

Marker 1 247.5MHz, 13.23dBm

It is important to note that performance can vary from unit to unit and across operating and environmental conditions.

Many AR Modular RF Booster Amplifiers offer Receive path LNA with similar functionality and performance, including the:

                                     • AR-50                     • AR-50C2

                                     • AR-50G                  • AR-50RC

                                     • AR-50RCS             • AR-50SAT75

                                     • AR-75
