The Class-E Power Amplifier with High Power and efficiency for radio communications

The use of smart radio equipment with high performance is one of the requirements of the smart police, and in this regard, it is necessary to consider operational requirements in the design of different parts of the radio transmitter and receiver. In the transmitter section, the power amplifier has some features such as power consumption, output power, and power added efficiency which are significant items in the design. This paper deals with the design of high- performance Class-E power amplifiers for the Radio communication systems. For this purpose, a cascade structure consisting of an amplifier is used as a switch to amplify the signal and an amplifier to increase reliability. In this circuit, one transistor is biased in the triode region as a switch and the other transistor is biased in the triode or saturation region. In this paper, a cascade class E power amplifier with a driver circuit and a compensator circuit is proposed to increase the output power and power added efficiency (PAE). The presented PA in this paper is appropriate for Radio communication. In this paper, the output power and PAE is improved by changing the structure of the PA. The PA has 2.6 GHz operating frequency, output power of 31.4 dBm, maximum PAE of 55.5%. The designed circuits are simulated with Cadence software.
