✦ Synopsis


broadside radiation patterns are observed, and the cross-polar levels are below Οͺ18 dB in both the E-and H-planes. The backward radiation is below Οͺ15 dB for both ports. The radiation patterns are also measured at other frequencies, and it is observed that the radiation patterns are stable across the bandwidth. The results are omitted here for brevity.

## Abstract We investigate on linearization performance of a digital predistortion (DPD) linearization technique based on the low memory power amplifier (PA) for wideband signals. The low memory PA is implemented using a 90W PEP LDMOSFET at 2.14 GHz, and an envelope short matching topology is appli

## Abstract In this article, we propose a wideband GaN HEMT power amplifier (PA) based on the dual‐fed distributed structure for 2.6 GHz WiMAX applications. For a continuous wave, the distributed PA shows the wideband performance compared with the conventional balanced PA. When the distributed PA i
