Agilent EEsof EDA Applications: Mixers, Frequency Converters, Modulators

-

Mixers, Frequency Converters, Modulators

Designers of mixers and other frequency-translation circuits can use harmonic balance simulation to characterize conversion loss, isolation, and noise. Transient Assisted Harmonic Balance (TAHB), a new simulation technique, offers insights into devices such as frequency dividers. Both of these capabilities - and many others - are part of Advanced Design System (ADS).

Additional design support is provided by a growing number of examples and training classes, and by Agilent EEsof EDA technical support.
