A Distributed Triband Impedance Matching Network Based on Multiresonant Networks

In the RF multiband applications, particularly in multiband power amplifiers, it is necessary to generate well-defined impedances at different frequencies in order to obtain the target output power. In this paper, the design, implementation and evaluation of a concurrent distributed triband impedanc...

Description
Summary:	In the RF multiband applications, particularly in multiband power amplifiers, it is necessary to generate well-defined impedances at different frequencies in order to obtain the target output power. In this paper, the design, implementation and evaluation of a concurrent distributed triband impedance matching network for operation at 2.4 GHz (Bluetooth), 3.7 GHz (WiFi) and 5.2 GHz (WiFi) are presented. The measurement results show that the reflection coefficients obtained are less than - 14 dB with maximum insertion loss of 1.4 dB.
