Abstract:
A system (200) includes a first differential amplifier (102) and a first transformer (X1) with a primary coil (L1) coupled to an output of the first differential amplifier (102) and with a secondary coil (L2) coupled to a load (RL). The system (200) also includes a second differential amplifier (104) and a second transformer (X2) with a primary coil (L3) coupled to an output of the second differential amplifier (104) and with a secondary coil (L4) coupled in series with the secondary coil (L2) of the first transformer (X1). The system (200) also includes a tuning network (204) coupled to a center tap node (206) between the secondary coil (L2) of the first transformer (X1) and the secondary coil (L4) of the second transformer (X2).
