Method for measuring the efficiency of power amplifiers linear integrated class using temperature measurements continuously

摘要

Method for measuring the efficiency of amplifiers linear integrated power class using temperature measurements continuously. # The present invention describes a method for measuring the efficiency of amplifiers linear integrated power class using temperature measurements continuously. Fig. 1 shows an integrated (1) circuit containing a linear power amplifier class A (2). The figure also shows the generator that supplies a DC voltage to drive the amplifier (3) and the signal generator (4) which amplifies the amplifier and delivered to the load (5). Measurements of the DC component of the temperature at selected points of the integrated circuit, in this case the point (6), allow measuring amplifier efficiency without using measuring equipment analog signals HF.
