Design of an ultra-broadband power amplifier using distributed network synthesis

Broadband RF Power Amplifier Design Methodology Using Sequential Harmonic Characterization

Radio Frequency Power Amplifier (RFPA) amplifies the communication signals to the required power level for transmission. It is the most power consuming stage in a transceiver chain; consequently, any improvement in terms of dissipated power and efficiency of the power amplifier affects the overall power budget of the transmitter. Also, efficient performance of the RF power amplifier over extend...

Design and characterization of a broadband SiC power amplifier

Due to the proximity of military and civilian bands at the relevant frequencies low frequency radar and EW systems needs amplifiers which combine a broadband coverage, a high output power and efficiency with a good linearity. The wide bandgap semiconductors SiC and GaN offer an impressive RF and microwave power-frequency capability [1] but relatively few SiC transistor amplifiers have been desi...

Design, Analysis and Simulation of a Linear Phase Distributed Amplifier

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....
