Dual-Mode Power Amplifier Module with In-Band Reconfigurable Output Power for Multifunctional Radar and Radio Communication Systems

Résumé

This paper presents a concept of dual-mode power amplifier (PA) module with in-band reconfigurable gain and output power. In the first mode, a wideband PA delivers a medium output power. This operational mode is particularly appropriate for ultra-wideband or multi-standard radio communication. In the second mode, a high power amplifier is turned on in order to deliver a high power signal within a sub-band for enhanced radar operation. This second mode allows both amplifiers to operate simultaneously in order to provide continuous service in sidebands. To demonstrate this concept, a network integrating a wideband medium output power PA and a narrowband high power PA is proposed. Both PA are based on low cost SiGe technology and optimized for maximum output power and Power Added Efficiency (PAE) in their operating frequency range. Simulated and measured results of a Printed Circuit Board (PCB) demonstrator validate the concept. The proposed sub-system would be of a great interest for multifunctional radar and radio communication systems.
