Multiband Amplifier, Vehicular, 50/75 Watt, 30-512 MHz with LNA


The A-7500 is a high-performance amplifier that uses advanced thermal techniques and materials to deliver outstanding thermal performance and ultra-fast processing of modern waveforms.

The A-7500 maintains a wide range of compatibility with today’s complex waveforms including SRW, ANW2™, EPLRS, ASCM, SINCGARS, HAVEQUICK, DAMA, IW and other TDMA waveforms.  Ultralife’s significant focus on tactical satellite operation has resulted in the A-7500’s great adjacent channel power performance and filtering coupled with a 10 dB gain low noise figure.  The A-7500 is an ideal solution for SATCOM-on the-Move (SOTM) applications.
