Design of a Wideband Adaptive Linear Amplifier with a DSB Pilot and Complex Coherent Detection Method

In this article, a novel adaptive linearization method, based on a double sideband (DSB) pilot in a feedforward power amplifier, is presented. The methods of generation and detection of the DSB pilot signal are described in detail. With this method, an...
In third generation (3G) mobile communication systems, linear amplification is required for linear modulations. Nonlinear amplification yields inter-modulation distortion (IMD) products and results in unacceptable spectral regrowth in adjacent channels. To achieve linear amplification, linearization techniques are usually employed. Various techniques have been developed to reduce IMD products in...

A Low Profile, Top-loaded Monopole Antenna with Four Small Posts

This article describes a low profile, wideband, top-loaded monopole antenna with four small posts. A post-type monopole is used to enhance the impedance matching. This provides a low radiation resistance within the usable band. Four small posts lead to...
Monopole antennas are used in mobile communications. A monopole antenna is a very simple and efficient radiating element. 1 The simple whip and monopole antenna are attractive for use in mobile handsets and repeater applications because of their omni-directional characteristics, simple structure and the inherent 2:1 size reduction over...
