چکیده
Thisarticlepresentsthedesign and fabrication ofa high power amplifierbased onwilkinson combiner. A 45W basic amplifier module isdesigned usinglaterally-diffused metal-oxide semiconductor (LDMOS) fieldeffect transistor (FET) PTFA260451E transistor. Wilkinson combineris used to combine two input powers toproduce 90W of power. Theproposed is researched, designed optimized usingadvanced design system(ADS) software.Experimental results show that thegain 11.5 dB greater than at 2.45-3.0GHz frequency band achieving maximum gain 13.5dB 2.65GHz centre frequency; output increased 49.3dBm; Power added efficiency 62.1% good impedances matching: reflection coefficient (S11)<-10dB, (S22)<-15dB. The can be for4G, 5G mobile communications andS-band satellite communication.

15 صفحه اولThe Design of Linearized Power Amplifier for Wireless Communications
The interest in higher data rate systems is rising very quickly in the area of wireless communications. High data rates mean high Peak to Average Ratio, PAR. This imposes big challenge on the linearity requirement of Power Amplifiers, PAs. The simplest technique that has been used is backing off the PA. However, this leads to very inefficient performance. A lot of more complex techniques were s...
