Over-10-dBm output uni-traveling-carrier photodiode module integrating a power amplifier for wireless transmissions in the 125-GHz band

Abstract

A rectangular-waveguide output UTC-PD module integrating a HEMT power amplifier has been developed for operation in the 125-GHz band. The fabricated module exhibits maximum output power of more than 14 dBm with nearly flat frequency dependence in the 115-135 GHz range. A 10-Gbit/s error-free wireless transmission at 125 GHz with a minimum sensitivity of-34 dBm for a bit-error-rate of 10-12 is also demonstrated using the fabricated module. © 2005, The Institute of Electronics, Information and Communication Engineers.
