AWR recently published a new white paper, The Advantages of Multi-rate Harmonic Balance Technology. To make harmonic balance analysis viable, AWR has pioneered a multi-rate harmonic balance (MRHB) technology within its APLAC family of harmonic balance and time-domain simulators. The capabilities provided with MRHB make it possible to solve entire complex subsystems such as mobile phone transceivers in a practical amount of time. The AWR white paper traces the use of harmonic balance in solving microwave problems, describes MRHB technology, and provides examples of its effectiveness when compared with traditional harmonic balance simulators.
AWR launched Version 2009 of their Analog Office high-frequency analog and RFIC design software. Analog Office Version 2009 includes AWR’s patent-pending multi-rate harmonic balance (MRHB) technology, which increases the speed and reduces the computer memory required to perform steady-state analysis of complex multi-tone designs such as those found in receivers and transmitters with multiple stages of upconversion and downconversion.
