Optically controlled 2.4GHz MMIC amplifier

In this paper a 2.4GHz MMIC amplifier for mobile applications is used to demonstrate the significant control that can be achieved in the amplifier's performance using optical illumination. The results presented show a 15dB variation in the amplifier's S21 figure and a 6 to 10dB variation in the input and output return loss when the incident optical power is varied.
