“…INTRODUCTION: In recent years considerable advances have been made in reducing the conversion losses and noise figures in mixers at microwave frequencies [1][2][3][4][5][6][7][8][9][10][11]. In order to correlate theoretically predicted improvements in mixer noise performance in practice, it is necessary to have an accurate measurement technique to determine both the effectire noise temperature and noise figure.…”

A new measuring technique has been developed, which enables the effective noise temperature Teff and intrinsic conversion loss Li of a lossy 2-port network to be determined directly. This technique when applied to a mixer, yields results which are in agreement with theoretical predictions (0.5 5Teff5 To; To ambient temperature) and may be measured with greater accuracy than has previously been possible using other methods. Practical results will be presented together with theoretical predictions based on a new approach to mixer noise analysis. This approach gives greater insight into the noise generation mechanisms and is more readily interpreted than other methods published to date in the literature.

In this article, a design of planar circularly polarized slot antenna is presented. The proposed antenna has a simple structure ABSTRACT: An indoor wireless millimeter wave system with an optical orthogonal frequency division multiplexing (OFDM) signal link was developed. Channel modeling for the multipath system was proposed, and the channels in a 60 GHz band were measured. Based on the model, system parameters were evaluated for various subcarrier modulations in OFDM systems. Link performance in a typical office environment under the line-of-sight channel condition and with a 30 km optical OFDM link was measured. V C 2011 Wiley Periodicals, Inc.
