10 GHz RF Power Amplifier for Continuous Wave Load Pull measurements

---

Introduction

We developed a custom rackmount amplifier capable of delivering a RF continuous power of 8W on a 50W load at a nominal frequency of 10GHz. The amplifier has been integrated into an existing on-wafer 2GHz CW RF Load Pull measurement system, thus extending its performace capabilities to the frequency of 10GHz , and is based on commercial amplifier modules, all manufactured by Kuhne Electronic GmbH, Germany, [1].

System description

The system consists of a cascade of three amplifier modules, Amp1, Amp2 and PA, as shown in Fig.1.
