## 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

β¦ 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 In this article, we propose a wideband GaN HEMT power amplifier (PA) based on the dualβfed 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
## Abstract This letter presents a design methodology for the millimeter wave amplifier using 90βnm Taiwan Semiconductor Manufacture Company (TSMC) CMOS technology. The proposed design scheme with mathematically modeled transmission lines and interstage matching transformers illustrates how to desi
In a recent paper, BANIK. K ~H N E , and BAUER (1996) investigated the use of Fisher's combination test for two stage sampling in terms of its power as compared to the optimal test in the pooled sample. The distributional assumptions corresponded to the application of paired comparisons and parallel
The new analytical method presented in this paper extends the principle of the equivalent small parameter method (ESP, an improved perturbation technique) to analyse and design Class E power ampli"ers. Using this method the analytical expression for the output voltage (or current), containing the fu
