QPA2598 6 12GHz 2.5 W GaN Driver Amplifier Product Description Qorvos QPA2598 is a packaged broadband driver amplifier fabricated on Qorvos QGaN15 0.15 um GaN on SiC process. Operating from 6 to 12 GHz, the QPA2598 achieves 2.5 W output power with a Power Added Efficiency of 30 % and harmonic suppression of -30dBc. Under nominal bias, it provides 22 dB small signal gain and 16 dB of large signal power gain. The QPA2598 is available in small form factor 4x4 mm overmold QFN which allows for easy system integration. The QPA2598 is an ideal choice to drive Qorvos high performing GaN HPAs allowing the user to run both driver and HPA off the same voltage rail.
