VSWR protection of power amplifiers using BST components
2016 German Microwave Conference (GeMiC), 2016A VSWR-protected ISM-band PA was realized using a BST based varactor for detuning of the input matching. Output VSWR levels of 30:1 can be tolerated by applying a varactor bias voltage of up to 20 V. The PA delivers 47.4 dBm output power at a maximum PAE of 49.5%. In case of high VSWR conditions the output power can be limited by detuning the varactor.

Planar low VSWR monopole antenna for UWB and LTE communication
2016 16th Mediterranean Microwave Symposium (MMS), 2016In this article, a printed planar low VSWR monopole antenna with a new modified ground plane for ultra-wideband (UWB) and 2.6 GHz LTE-band applications is presented. The dimensions of proposed antenna structure are optimized to achieve low VSWR performance. The antenna is fabricated on a low cost FR4 epoxy substrate and tested.

Limitations of the Free Space VSWR Measurements for chamber validations
AMTA 2016 Proceedings, 2016Free 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 with the boresight angle while traveling along a linear path to record the receive pattern.

A 24-31GHz 28nm FD-SOI CMOS Balanced Power Amplifier Robust to 3:1 VSWR for 5G Application
European Microwave Conference, 2022This paper presents a broadband balanced power amplifier (PA) for 5G mm-wave applications. Thanks to its balanced architecture, the PA exhibits a great robustness to active voltage standing wave ratio (VSWR).
