Description
Summary:A Wilkinson power divider (WPD) with superior merits including compact size, high reliability and high performance is proposed based on the GaAs-IPD technology. The proposed WPD is achieved by replacing the transmission line of the conventional WPD with a pi lowpass network. Primary components, such as inductors and capacitors are designed and fabricated on the merits of high Q-factor and appropriate value, and they are subsequently used to construct a compact WPD with a chip area of 1070 μm × 960 μm (0.01 λ 0 × 0.01 λ 0 ). Moreover, the SOT-6 packaging method is applied and reliability tests including temperature, humidity, vibration and pressure test are carried out to further guarantee a long-term stability and commercial success. The packaged measurement results show excellent RF performance with insertion loss below 3.7 dB, return losses greater than 24 dB and isolation greater than 19.6 dB at 900 MHz.
