TGA2958-SM 1318GHz 2W GaN Driver Amplifier Product Description The TGA2598-SM is a packaged Ku-band amplifier fabricated on Qorvos 0.1um5 GaN on SiC production process (QGaN15). Operating over a 1318GHz bandwidth, the TGA2598-SM delivers 2W of saturated output power with 20dB large signal gain and > 25% power-added efficiency. This, along with >25dB small signal gain allows it to support a variety of low power Ku- band systems or as a linear, high-voltage driver for Qorvos line of high power Ku-band amplifiers. 14 Lead 4 x 4 Air Cavity Laminate Package Packaged in a 4x4 air-cavity package for high performance and easy handling, the TGA2958-SM is fully matched to 50ohms with integrated DC blocking capacitors on both I/O ports for simple system integration. This makes for an ideal Product Features general purpose RF amplifier which can provide needed functionality across both commercial and defense related Frequency Range: 1318GHz markets.
