MULTIMODE OPERATION FOR DIFFERENTIAL POWER AMPLIFIERS |
摘要 |
An RF circuit for wireless devices comprises a single differential power amplifier and an impedance balancing circuit for each frequency band. The impedance balancing circuit serves both to provide an appropriate impedance at the output of the amplifier as the operating mode of the device changes, and also transforms the differential output of the amplifier to a single-ended output. The impedance balancing circuit optionally comprises a BALUN circuit and a variable capacitor that is varied as the operating mode changes in order to vary the impedance at the output of the amplifier. |
