A dual-frequency wilkinson power divider
TL;DR: In this paper, a Wilkinson power divider operating at two arbitrary different frequencies is presented, and the structure of this power dividers and the formulas used to determine the design parameters have been given.
Journal ArticleDOI
A dual-frequency Wilkinson power divider: for a frequency and its first harmonic
TL;DR: In this paper, a Wilkinson power divider operating not only at one frequency f/sub 0/ but also at its first harmonic 2f/sub 1/6-wave transmission line is presented.
Patent
Power amplifier for amplifying high-frequency (H.F.) signals
Manfred Berroth,Lei Wu +1 more
TL;DR: In this paper, a H.F. power amplifier is disclosed having a plurality of branches (10, 11, 12) switched in parallel with resistors (R2, R5) enabling the voltage (UlDS) applied to the amplifier elements (T1,…, T4) to be set at a fraction of a supply voltage (Ud) applied on the branches.
Proceedings ArticleDOI
Comparison of a single-ended class AB, a balance and a Doherty power amplifier
TL;DR: Comparing the experimental results, this paper gives an overview of the advantages and disadvantages of each individual power amplifier.
Journal ArticleDOI
A 900-MHz 29.5-dBm 0.13-μm CMOS HiVP Power Amplifier
TL;DR: In this paper, a class A power amplifier for the global system for mobile communication in Europe was developed using ST 0.13-mum CMOS technology, and the measurement results showed that the output power of 29.5 dBm has been achieved at the frequency of 900 MHz.
