Abstract: This article presents an adaptive digital predistortion (DPD) linearizer for user equipment (UE) power amplifiers (PAs) assuming a realistic 5G scenario with dynamic frequency and signal ...

When an electric wave travels through an antenna system—including the receiver, feed line, antenna, and free space—it encounters impedance variations at different interfaces. These variations cause ...

The R&S®ZNB vector network analyzer together with the R&S®HF907 double-ridged waveguide horn antenna provides fast and accurate TD SVSWR measurements in line with ANSI C63.25. Sept. 23, 2020 The ...

Voltage Standing Wave Ratio (VSWR) is a fundamental parameter that measures the efficiency of radio frequency (RF) power transmission from a source through a transmission line to a load. A simple way ...

Our free VSWR / Return Loss Calculator is a powerful tool designed to help you assess and optimize the performance of your RF and microwave transmission systems. By inputting key parameters, you can ...

I work in an RF lab and certain little things are performed frequently. Visitors, for example, are often more comfortable using Watts while engineers prefer dBm or other dB variants, and it's helpful ...

Load-pull tuning systems provide tremendous insight into high-frequency devices under variable-impedance conditions. In terms of device and component optimization, for example, a loadpull tuner makes ...

The return loss of signal and voltage standing wave ratio (VSWR) are two of the most important characteristics of an antenna. So, their proper understanding is essential for a good antenna design.

Abstract: Free Space VSWR measurement has been the de facto standard method for anechoic chamber performance evaluation for more than 50 years. In this method, a probe antenna is first kept parallel ...

Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The previous sections looked at the basics of impedance and VSWR.
