<p>The amplifier (VS) has two amplifiers (V1, V2) connected in antiparallel, the two couplers (K1, K2). Two decoupled terminals of a first coupler (K1) are connected to the input of the first amplifier (V1) and to the output of the other amplifier (V2) respectively. The amplifier (V1) output is connected to a first decoupled terminal of the second coupler (K2), whose second decoupled terminal is connected to the amplifier (V2) input.</p> |
