A General Adaptive Digital Predistortion Architecture for Stand-Alone RF Power Amplifiers

In this article, two novel topologies of compact-size dual-band single-ended-tobalanced power dividers that are loaded with open-and short-ended stubs are presented.Quarter-wavelength open-ended stubs and half-wavelength short-ended stubs are respectively exploited in the proposed dual-band power-divider configurations to incorporate the dual-band functionality into them for flexibly-adjustable dual-frequency-ratio specifications. Each engineered five-port power-divider circuit features high in-band input/output power-matching levels, high in-band powerisolation levels between the two differential-mode outputs, and high commonmode-rejection levels in a broad spectral range. Two microstrip prototypes designed at 0.9/1.8 GHz (GSM bands) and 1.57/2.45 GHz (GPS and WLAN bands) are constructed and characterized for experimental-demonstration purposes.
