Pre-amplifier integrated uni-travelling-carrier photodiode module for operation in 120 GHz band

Abstract
A pre-amplifier integrated UTC-PD module with a rectangular-waveguide output port for operation in the 120 GHz band has been realised. The integrated amplifier achieves an 8 dB increase in the output power, resulting in an equivalent responsivity as high as 1.0 A/W. A 10 Gbit/s error-free wireless transmission at 125 GHz has also been demonstrated using the fabricated module.
