Abstract :

In this article, two novel dual-band matching networks (MNs) with adapted frequency are designed, constructed, and measured for a power amplifier (PA) module at the central frequencies of f_1=2.4GHz and f_2=5.8GHz. The proposed networks are to be utilized in a concurrent dual-band adaptive PA. In some high-frequency applications, active switching components are also employed in circuits to open and close connections or even change their branch-line parts. Besides, return and isolation losses (RLs and ILs) are regarded as the fundamental parameters to describe the performance of such components. Using a PIN diode, called the BAR50-02 (Infineon Technologies, Germany), two types of simultaneous MNs with the ability to change the frequency bands in a wide range are presented. Moreover, the equivalent circuit of the PIN diode, the integrated concurrent MNs, and the ideal circuit components are provided along with the relevant formulas. The dual-band MNs, characterized with frequency adaptation, are then designed, simulated, and built, and finally the circuit characteristics are measured within both bands.
