Bothell, WA — November 27, 2018 — AR Modular RF has released a new tactical booster amplifier that extends the range of communications in the 30-88 MHz frequency band. 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, 50W booster amplifier complies with Military Standards 461E and 1275. It requires no tuning, switching, or adjustment. Automatic band-switching occurs, and three harmonic filter bands cover the 30-88 MHz 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 multi-band antennas in the 30 to 88 MHz band. The amplifier will be bypassed automatically in case of a system failure, 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.
