Abstract

A power amplifier cell comprising a first power amplifier (102), a second power amplifier (104) and a balun. The balun comprises a first inductor (118) and a second inductor (122) that define a first transformer; and a third inductor (120) and a fourth inductor (124) that define a second transformer. The following: (i) a parasitic capacitance (106) of the first power amplifier; (ii) a leakage inductance (110) of the first transformer; and (iii) a capacitive coupling (114) 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 (108) of the second power amplifier; (v) a leakage inductance (112) of the second transformer; and (vi) a capacitive coupling (116) between the third inductor and the fourth inductor, contribute to a second impedance matching circuit for the second power amplifier.
