Journal ArticleDOI
Optimum single antenna full duplex using hybrid junctions
TL;DR: It is shown that the maximum achievable isolation in EB duplexers is proportional to the variance of the antenna reflection coefficient with respect to frequency, and that the operational environment can have a significant impact on isolation performance.
Journal ArticleDOI
Electrical balance duplexing for small form factor realization of in-band full duplex
TL;DR: Results demonstrate the degradation in duplexer isolation due to imperfect system adaptation in user interaction scenarios, and requirements for the Duplexer adaptation system are discussed.
Journal ArticleDOI
Multichannel and Wideband Power Amplifier Design Methodology for 4G Communication Systems Based on Hybrid Class-J Operation
TL;DR: A methodology for the design of multichannel, wideband, highly efficient hybrid Class-J power amplifiers for fourth-generation (4G) communication transmitters is proposed, based on the automatic generation and evaluation of a vast number of output matching networks of the same topology but different dimensions.
Journal ArticleDOI
General Design of Multiway Multisection Power Dividers by Interconnecting Two-Way Dividers
TL;DR: It will be shown that the performance of multiway dividers constructed by interconnecting even-number-section two- way dividers deteriorates significantly as the number of output ports increases.

Signal processor for use with a power amplifier in a wireless circuit
Tayfun Nesimoglu,Kevin A. Morris +1 more
TL;DR: In this paper, a signal processor separates an input signal into first and second processing paths, the first processing path generating a pulse train signal which is a digitised envelope signal, and the second processing path comprising phase processing means operable to generate a constant envelope phase signal.
