An X-band, Low Cost, LTCC Double-balanced Mixer

Double-balanced mixers are used extensively in transmitters and receivers. For frequencies above 5 GHz the designs are normally realized using strip line and microstrip techniques. This is because distributed element baluns become smaller in size and more attractive for design as the frequency increases. Semiconductor-based mixers are the most...

Cross-modulation in a CDMA Mobile Phone Receiver

Determining cross-modulation interference is an important factor in the design of a code division multiple access (CDMA) mobile transceiver. The cross-modulation interference level directly affects the performance of the receiver's ability to overcome the spurious interferences, such as what the IS-98 1 calls single tone desensitization. A few papers...

The Concept of Predistortion

The intention of this article is to provide a tool for the design of a predistorter, a component intended to correct unwanted nonlinear effects in power amplifiers. In order to come up with a design, a concept of predistortion is discussed. The conclus...
This article continues the trend of previous publications, 1,2 to simplify the prediction of RF performance of systems designed for wireless digital communications. The first shows the correlation between sidelobes and intermodulation (IM) products. Sidelobes are the result of the spectrum re-growth when a digitally modulated signal is applied...
