Abstract
Photonic generation of high-power pulsed microwave signals is demonstrated using charge-compensated modified unitraveling-carrier photodiodes. The impulse response without RF modulation achieved unsaturated peak voltage of 33.5 V and full-width at half-maximum of 50 ps. The peak power levels for gated modulation at 1 and 10 GHz were 41.5 dBm (14.2 W) and 40 dBm (10 W), respectively.
