The characteristic impedance of L-type and T-type networks are investigated for the distributed amplifier (DA) design respectively. The analysis shows that the L-type network has better frequency characteristics than the T-type one. Two distributed amplifiers with L- and T-type network are designed with 2-μm GaAs HBT process for comparison. The simulation results demonstrate that the DA with L-type network has broader 3-dB bandwidth than that of the DA with T-type network.
