A G-Band (140-220 GHz) planar stubbed branch-line balun in BCB technology

• A G-Band planar stubbed branch-line balun isdesigned and fabricated in 3μm thick BCB technology. Thistopology of the balun does not need thru-substrate via hole orthin-film resistor which makes it extremely suitable for realizationon single-layer high-resistivity substrates commonly used atmillimeter-wave or post-processed BCB layers on top of standardsemi-insulating wafers. The design is simulated and validated bymeasurements. Measurement results on two fabricated back-tobackbaluns show better than 10 dB input and output return lossand 3.2 dB insertion loss from 140 to 220 GHz.
