Description
Summary:ABSTRACT In this article, we present a new wideband hybrid coupler for millimeter‐wave applications realized in the BiCMOS9MW 130‐nm process from STMicroelectronics. The fabrication of two slightly different couplers demonstrates the wideband performance associated with miniaturized size, thanks to the use of meandered transmission lines and lumped capacitors. The best coupler provides a −10‐dB matching bandwidth of 42% with an insertion loss of 0.6 dB and a phase shift of 88° at 60 GHz. The amplitude imbalance and the phase imbalance stay, respectively, within ±1 dB and ±5° over 27 and 36%. These state‐of‐the‐art results are compared to recently published results obtained with comparable hybrid couplers. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:587–590, 2014
