CMOS based Tunable Matching Networks for cellular handset applications

Summary form only given, as follows. The explosion in the number of connected cellular devices increasing data bandwidth requirements has grown the number of bands a modern cellular device must support. A potential solution to this problem is achieved by the use of Tunable Matching Networks. This paper outlines the challenging requirements placed on tunable components, presents a Tunable Matching Network utilizing Digitally Tunable Capacitors (DTCs), and proposes a method for evaluating the improvement this network brings.
