Abstract
The invention relates to a photodiode chip which has a great limit frequency and a junction from the active photodiode area of a photodiode mesa to the output pad of the high-frequency output of the photodiode chip. The aim of the invention is to further increase the bandwidth factor of photodiode chips. Said aim is achieved by establishing the connection from the photodiode mesa to the output pad by means of a high-resistance wire with impedance (Z) which is spread across the length thereof and is at least as high as the load impedance (Z) effective at the output pad.
