Technical Feature A New Type of Amplitude Equalizer for In-band Flatness Improvement There is a growing need in modern communication systems for low cost bandpass filters of small size, high selectivity and flat passband response in order to meet the demands for inter-channel power balance, and to avoid interference....

Technical Feature Intermodulation Products for a Mixer Subjected to a Multi-carrier Signal Applying a multi-carrier signal to a mixer leads to a large range of intermodulation products. To perform a link budget of a multi-carrier transmit-receive system, it is important to predict the location and magnitude of those intermodulation...

Tutorial Externally Induced VCO Phase Noise This article describes the degradation of VCO phase noise due to noise on tuning and supply lines, particularly from tuning source resistance and supply voltage regulators. Dennis Colin Micronetics Wireless Hudson, NH VCOs, especially low noise wideband units, are extremely sensitive voltage-to-frequency converters,...
