This paper presents the impedance matching of the magic-T tuner to overcome the matching dead zone of three-stub waveguide tuner. The S-parameters corresponding to different E-arm and H-arm heights of ...

In this paper the design of a fully differential Ka-Band power amplifier (PA) with transformer based impedance matching is presented. The PA is realized in a 250 nm SiGe BiCMOS process. At a target ...
