We have been using Microwave Office for many years at Roke Manor Research, and have been consistently impressed by its ease of use and accuracy. The 2004 version brings significant improvements and additions, including very accurate prediction of oscillator phase noise, and a much faster harmonic balance simulator. A welcome new option is the seamless integration of an HSPICE® time-domain simulator. Perhaps the most impressive capability is real-time tuning of a nonlinear circuit using both time- and frequency-domain simulations simultaneously.
