Ultralife A-2303 military amplifier

Ultralife’s A-2303 is a compact, energy-efficient military amplifier that serves depot support applications. Weighing 540 g and delivering 20 W with ~0.75 to 5 W of RF drive power, it is compatible with low-power personal role radios (PRRs) that are used in military and industrial applications across the globe. The amplifier is also designed for easy integration into existing equipment and is equipped with RS422 (I/O) for remote control and status reporting.

With an internal power supply allowing operation from 10–36 VDC and a frequency range of 30–512 MHz, the device is claimed to be the smallest, lightest radio frequency (RF) amplifier available. It features a radio-agnostic design, user-replaceable connectors and an optional auxiliary cooling accessory, to reduce operating temperatures and prolong lifespan in extreme conditions.

Compared to previous models, the A-2303 supports a broader range of input power, making it compatible with smaller, lighter batteries such as the Land Warrior or Conformal batteries manufactured by Ultralife’s Battery and Energy division. It also features improved timing and power efficiency, higher gain and good thermal performance, making it suitable for both dismounted (on the person) and vehicle applications. System engineers and integrators can undertake in-country repair and calibration using documentation, instrumentation and LabVIEW test routines.
