TS-063156 — In the era of 5G and beyond, wireless base station infrastructures require power amplifiers (PAs) that maintain high efficiency from backoff to peak power level. Conventional Doherty PAs, while popular, are inherently narrowband due to their reliance on a quarter-wave transmission line (TL). This …

TS-063155 — With the rapid growth in modern communication, transmitter systems must use a wider fraction of the spectrum, to support the continuously increasing data rate. In addition, signals with large peak-to-average power ratio (PAPR) are used in communication systems to increase the spectral efficiency. …

TS-063148 — In an era of rapid growth in modern communication, there is an increasing demand for multi-band and broadband power amplifiers (PA) for signals with large peak-to-average power ratio (PAPR). The PA, being one of the most power-consuming components in a transmitter system, needs to achieve high ave…
