Designed for military applications, the model SM2560-47GN power amplifier from Stealth Microwave delivers +47 dBm typical output power (50 W) from 2.5 to 6.0 GHz. Based on gallium nitride (GaN) device technology, the amplifier provides 45 dB linear gain with +/-2 dB gain flatness across the frequency range. It has an integral heat sink and features over-voltage protection and thermal protection with an automatic reset feature. The temperature-compensated amplifier maintains gain variations within +/-1 dB over a temperature range of -40 to +85C. Available as a module (7.50 x 3.97 x 0.79 in.) or in a rack-mount unit, the power amplifier draws 7 A from a +28-VDC supply.
