Abstract

The protection of phased array T/R modules from high input power levels is an important aspect in reducing vulnerability of radars and communication systems RF electronics in modern military platforms. Different categories of threats can damage the sensitive electronics in the phased-array radar, like hostile high power electro-magnetic (HPEM) pulses or the radar’s own transmitted signal. In this paper, a novel approach to this problem is proposed, which consists of distributing the protection at different levels of the T/R module instead of confining it to a single device, as it is currently done in most existing systems. Enabling technologies for this solution are briefly described and several examples of protection architectures developed at TNO are presented
