In this paper, an improved empirical behavioral model for radio-frequency power amplifiers (RF-PAs) is presented. The model was implemented in a commercial nonlinear microwave simulator. It belongs to the category of bandpass PA models, which exhibits memory effects due to the low frequency dependen

Abstract
This paper demonstrates the use of the power‐over‐fiber concept for wireless applications, which removes the need for DC power supplies at the remote network.The article shows results using low cost lasers, photodiodes, a highly efficient voltage booster circuit (>80%), and rechargeable batteries. Results show that with the best choice of each component, the system can operate for 8 h per day over 200 m MMF for 41 days. System modeling shows that the system can operate indefinitely for 5 h a day over 200 m MMF. Finally, the system was tested for a 802.11 g WLAN application over 200 m MMF and a maximum range of 4 m at 500 kbps can be obtained. © 2011 Wiley Periodicals, Inc.

We prove the equivalence between flatness of a complex algebraic map to a smooth variety of dimension n and torsion freeness of its nth fibered power, under the assumption that the source space is of pure dimension. This generalizes the corresponding result for finite maps due to Auslander and prove
## Abstract A method for enabling efficient duplex communication in a RoF (radio‐over‐fibre) system by generating and diplexing signals in sideband modes is demonstrated. Data in the mm‐wave band with a rate of 155 Mbps over 5 km of an optical link are transmitted using orthogonal frequency divisio
## Abstract Lithium niobate based Mach–Zehnder electro‐optic modulators are increasingly being used in high‐speed digital as well as analog optical links. Depending on the application, digital or analog, the bias point of such a modulator is held constant at a particular point on the sinusoidal ele
In this article, a broadband approach to high-efficiency power amplifier performance, based on the parallel-circuit Class E mode, is discussed. Results for a practical implementation of multi-band and multi-mode handset power amplifiers are shown. Measurements demonstrate the feasibility of the conc
