Abstract :
An optically controlled coupled line microstrip attenuator on a high resistivity silicon substrate in the 3GHz -7GHz band has been investigated for 10 dB and 25dB attenuation control for one-port and twoport optical illumination respectively by 20mW, 650nm laser diodes. The attenuator has been modeled by the PUFF circuit simulator and the simulated results correspond to the experimental results.
