Title: CIRCUIT ARRAY FOR ADAPTING AN AMPLIFIER TO A HIGH FREQUENCY LINE AND UTILIZATION OF SAID CIRCUIT ARRAY
Abstract:
The invention aims at minimizing the components required for adapting an amplifier (PA) to different frequency bands. To this effect, the inventive circuit has a first capacitor for uncoupling the negative half-wave of the transmission signal, which is rectified with the aid of a diode (D2) and stored in a second capacitor (C2). If required, the stored negative voltage is fed back to an additional diode (D1) by means of two resistors (R1, R2) and an inductor (L1).
