In this letter, a novel dual-band coupler made of only three coupled microstrip–slotline (CMSL) sections is proposed to achieve a tight coupling with a high band ratio in a small size. A desired ...

This work describes the design of a compact, 60 GHz, SPDT switch implemented using PIN diodes in a 130 nm SiGe BiCMOS technology. The SPDT RF switch employs a novel shunt-series topology with a ...
