20-Watt 30-512 MHz Amplifier

MBA-21R+

Overview

The MBA-21R+ features A-320 technology inside the chassis.

Specifically, it provides all the advantages of the A-320 along with built-in Low Noise Amplification (LNA) for UHF SATCOM operation.The MBA-21R+ accepts DC input voltages from 9-36 VDC and can be powered from a vehicle cigarette lighter.

Like the A-320, the MBA-21R+ is very power efficient. Unlike other amps that require two batteries to achieve 20-watt power, the MBA-21R+ operates from a single 5590 battery with a supply voltage of 22-36 VDC. When powered by a 5390 battery, operational life can be extended to 24 hours (based on a 15% transmit duty cycle).
