AR Modular RF’s AR-50SE To Be Used In Support Of The U.S. Army HMS Radio Program


AR Modular RF will provide its AR-50SE tactical booster amplifier to Collins Aerospace to be used in its “Handheld, Manpack and Small Form Factor” (HMS) Radio Program for the U.S. Army.

AR Modular RF is known for its ability to respond to customers’ needs, building new equipment or modifying existing booster amplifiers to meet specific requirements.

The Model AR-50SE is a fully automatic band-switching RF booster amplifier for multi-band Tactical Radio equipment employing legacy, proprietary and emerging waveforms. The amplifier which is a sub-banded version of our JITC certified AR-50 multi-band product covers the frequency band of 30-88 MHz using high speed auto switching filters to assure harmonic suppression and is SINCGARS compatible.

This portable, rugged, 50-watt booster amplifier complies to Military Standards 461E and 1275. It requires no tuning, switching or adjustment. Automatic band-switching occurs, and three harmonic filter bands cover the 30-88MHZ band for acceptable harmonic distortion levels anywhere within the band.

Amplifier performance, including T/R switching, is fully automatic. Protection is provided against overheating, excessive VSWR, high-level RF input power and inadvertent DC polarity reversal. The unit does not shut down or bypass when presented with a high VSWR condition, which is often found on multiband antennas in the 30 to 88MHz band. The amplifier will be bypassed automatically in case of a system failure, or loss of DC power, or when the input signal frequency is out of range. The amplifier includes RF sensing, T/R switching, Automatic Level Control (ALC), and DC power transient protection.
