A 537W saturation output power (Psat) asymmetric Doherty amplifier for 2.6GHz band was successfully developed. The main and peak amplifiers were implemented with Psat of 210W and 320W GaN HEMTs. The newly developed 320W GaN HEMT consists of a single GaN die, both input and output partial match networks and a compact package. Its output matching network was tuned to inverse class F and a single-ended...
A 40W average output power asymmetric Doherty power amplifier (PA) for 2.6GHz band was developed using broadband inverse class F GaN HEMTs. The Doherty PA was successfully designed for 2.5GHz–2.7GHz using simple small signal analysis with optimum load impedance obtained by load-pull measurement. To the main and peak amplifiers the saturated power of 105W and 160W GaN HEMTs were applied, respectively...
Background Although GIST generally occurs in the digestive tract, such as the stomach, and small and small intestine primarily, Omental GIST tumours are very rare. Case Presentation A 63-year-old male patient, who recognized an abdominal tumor 1 year before admission, had a slight expansion of the tumor, reduction of the body and malaise, was consulted to our hospital. Abdominal CT and MRI revealed...
