  • Abstract
    A broadband amplifier operating over 26.5 to 40 GHz has been developed by using 0.25-µm gate HEMTs. The amplifier has been fabricated by cascading five unit amplifiers. Two balanced-type unit amplifiers are used in an input and an output stages to realize good input/output VSWRs . Three single-ended unit amplifiers are installed in the intermediate stages to achieve higher gain. The developed amplifier shows a noise figure of <= 7.0 dB, a gain of 18.2 +- 1.6 dB and inputfoutput VSWRs of <= 2.0 over 26.5 to 40 GHz.
