Abstract :
We compare two uni-traveling-carrier photodiodes for high power applications. Saturation current is increased from 62 mA to 90 mA at 20 GHz due to improved series-resistance and heat power dissipation. The associated 3 -dB bandwidth is shown to increase simultaneously from 30 GHz at 40 mA to 32 GHz at 70 mA.
