A new high speed photodetector has been fabricated by using a distributed amplifier and p-i-n photodiode combination. A 3 dB bandwidth of 17 GHz was achieved. The noise level and detection sensitivity have been measured and an average input noise current of 20 pA/Hz was achieved. This corresponds to an optical sensitivity of -21 dBm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
