Output for Generic Real-Time (GRT) Targets Now Supported

You can use Real-Time Workshop^® software with RF Blockset™ software to generate standalone executables for GRT targets.

Nonlinear Modeling of Physical Mixers and Amplifers Improved

Previously, the nonlinear algorithm that was used by the physical mixer and amplifier blocks was appropriate only for high-powered amplifiers (HPAs), which operate close to the saturation point. The new nonlinear algorithm can also be used for mixers and amplifiers that operate far below the saturation point and yield very weak intermodulation products.

As with the old algorithm, the saturated output power of the new algorithm is 8.3 dB below the third-order output intercept point (OIP3).

Where the previous algorithm was piecewise linear, the new nonlinear algorithm uses a linear plus cubic curve of amplitude-in versus amplitude-out to simulate the behavior of systems that operate far below the saturation point. Where the previous algorithm assumed a third-order intercept point (IP3) reference impedance of 50 ohm that was irrespective of the S-parameter reference impedance, the new algorithm assumes that the S-parameter reference impedance is the same as the IP3 reference impedance used to convert from IP3 to the amplitude-related constants in the model.

Note   The corresponding Z and Y algorithms still assume a fixed 50-ohm conversion factor from specified power to modeled amplitude.
