The present invention relates to a power servo-loop in particular for controlling a power amplifier, the loop comprising a detection circuit (100) having coupling means (1) for taking off RF signals, and a detection unit (400) for delivering a detection signal (Vdet) partially representative of a first RF signal taken off by the coupling means. The detection circuit of the invention comprises, between the coupling means and the detection unit, detection control means (21, 22, 4) for substantially eliminating an "interfering" second RF signal also taken off by the coupling means, such that the detection signal is entirely representative of the first RF signal.

Water entry of spinning spheres (2009, neutral): “Below a critical impact velocity and critical wetting angle, the flow remains attached until it surrounds the sphere completely and meets at the top, causing a jet of fluid to form upwards without the presence of an air cavity (Duez et al. 2007).”
Generation and breakup of Worthington jets after cavity collapse. Part 1. Jet formation (2009, background): “The differences pointed out above set our system somewhat apart from other impact studies (Glasheen & McMahon 1996; Duclaux et al. 2007; Duez et al. 2007; Grumstrup, Keller & Belmonte 2007; Aristoff & Bush 2009; Do-Quang & Amberg 2009).”
A novel and inexpensive technique for creating superhydrophobic surfaces using Teflon and sandpaper (2010, background): “As seen in equations (1) and (2), this increase in surface roughness is a mechanism by which contact angle can be increased.”
Water entry of small hydrophobic spheres (2009, background): “An important foundation of the present study is the observation reported by Duez et al. (2007) that hydrophobicity promotes air entrainment by impacting spheres.”
Air entrainment during impact of droplets on liquid surfaces (2013, background): “This has not been tested, but is deduced from the related experiments by Duez et al. (2007) in which the splash occurrence is influenced by the wettability of the surface.”
Moving Contact Lines: Scales, Regimes, and Dynamical Transitions (2013, methodology): “Figure 5 represents a broad collection of contact lines that spontaneously develop a V-shape (Blake & Ruschak 1979, Delon et al. 2008, Duez et al. 2007, Le Grand et al. 2005, Peters et al. 2009, Podgorski et al. 2001, Winkels et al. 2011).”
