  • Abstract
    We report the development of a broadband 3D balun circuit exhibiting superior performance due to ground plane removal and unique 3D features. The 3D balun provides balancing action from 2.05 GHz to 2.65 GHz with ±5 degrees and ±0.5 dB phase and amplitude imbalance, respectively. The design concept can be generalized to most frequencies and/or fabrication processes. In addition we present the performance of a 3D X-band amplifier implemented using a 12-layer low temperature cofired ceramic (LTCC) process
