Abstract
A power amplifier cell comprising a first power amplifier, a second power amplifier and a balun. The balun comprises a first inductor and a second inductor that define a first transformer; and a third inductor and a fourth inductor that define a second transformer. The following: (i) a parasitic capacitance of the first power amplifier; (ii) a leakage inductance of the first transformer; and (iii) a capacitive coupling between the first inductor and the second inductor, contribute to a first impedance matching circuit for the first power amplifier. Also, the following (iv) a parasitic capacitance of the second power amplifier; (v) a leakage inductance of the second transformer; and (vi) a capacitive coupling between the third inductor and the fourth inductor, contribute to a second impedance matching circuit for the second power amplifier.
