  • Abstract
    A simple optimisation procedure for the design of travelling-wave amplifiers with two parallel gatelines and a common drain line is presented which utilises the full impedance matching potential involved. The parameters to be optimised for best broad-band performance of the amplifier are the characteristic impedances and, simultaneously, the line section lengths. The predicted performance of a design parallel distributed amplifier, employing eight typical 0.7 ¿m × 300 ¿m FETs, i.e. four for each of the two parallel gate-lines, shows 8.8 ± 0.5 dB gain over the frequency range 2¿16.5 GHz.
