75-Watt Multiband Amplifier

A-3575

Overview

The A-3575 provide the same trademark power and performance associated with all AMTI amplifiers. Users benefit from consistent amplification across the 30-512 MHz range. Operators select 12, 25 and 50/75 watts. The 50/75 watt power setting provides 75 watts of power in the UHF TACSAT uplink band and 50 watts everywhere else.

Each unit comes with an easy to install ‘shock and vibration’ isolating mounting tray and fused power cable. The amps weighs less than 11 pounds. The A-3075 has a charging pocket for the MBITR radio built-in its 'shock and vibration' tray.

Like all AMTI amps, it is true HAVEQUICK and SINCGARS compatible (as opposed to many other amps that are merely capable). Another important distinction is our exceptional harmonic filtering and auto-sensing frequency hopping technology. As a result, the A-3575 and A-3075 will not inadvertently jam or desensitize other communication nets operating in the same area.

The amp supports Demand Assigned Multiple Access (DAMA) and other JTRS waveforms. The units are MIL-STD 461E and MIL-STD 810F compliant.

More than Quality Control

Each unit is put through vigorous testing and analysis prior to shipment. When you power up this amp, be confident that you get the performance you expect … not part of the time, all of the time.
