Abstract :
In this paper, we report the design of an amplifier with a flat group delay and gain for use in a high-speed D-band wireless transceiver without a group delay equalizer. Compared with a conventional amplifier with a group delay equalizer, the amplifier have achieved a decrease in the power consumption and an increase in the communication speed. The peak gain is 8.1dB at 118.6GHz with a power consumption of 19.8mW. The 3dB bandwidth is 20.4dB with a group delay variation of 43.3 to 65.8ps.
