Abstract :
Advanced design techniques of GaAs wideband direct-coupled amplifiers are described. The amplifier achieved 20-dB gain with a 3-dB bandwidth of 13 GHz and 5-7 dB noise figure. An equalizing amplifier module consisting of amplifier and variable attenuator MMICs exhibited a high gain of 43 dB over 10-GHz band with a controllable gain of 20-43 dB
