RF Blockset
设计and simulate RF systems
RF Blockset™ provides a Simulink®用于设计RF通信和雷达系统的模型库和仿真引擎。
RF Blockset lets you simulate RF transceivers and front-ends. You can model nonlinear RF amplifiers to estimate gain, noise, even-order, and odd-order intermodulation distortion, including memory effects. For RF mixers, you can predict image rejection, reciprocal mixing, local oscillator phase noise, and DC offset. RF models can be characterized using data sheet specifications or measured data such as multiport S-parameters. They can be used to accurately model adaptive architectures, including automatic gain control (AGC), digital predistortion (DPD) algorithms, and beamforming.
RF预算分析仪应用程序允许您自动生成收发器模型和测量测试台，以验证性能并设置电路包络多载波模拟。
使用RF BlockSet您可以在不同级别的抽象中模拟RF系统。电路包络模拟使得具有任意拓扑的网络的高保真，多载波模拟。等效基带库启用单载波级联系统的快速，离散时间模拟。
Get Started:
RF Budget Analysis and Top-Down Design
使用RF预算分析仪应用程序to design a cascade of RF components. Build your system graphically or script it in MATLAB®。Analyze the budget of the cascade in terms of noise, power, gain, and nonlinearity.
设计RF transceivers for wireless communications and radar systems. Compute the budget considering impedance mismatches instead of relying on custom spreadsheets and complex computations. Use harmonic balance analysis to compute the effects of nonlinearity on gain and on second-order and third-order intercept points (IP2 and IP3). Inspect results numerically or graphically by plotting different metrics.
快速射频仿真
Go beyond analytical computations and simulate the effects of leakage, interferers, direct conversion, reciprocal mixing, and antenna coupling.
从RF预算分析仪应用程序，为多载波生成模型和测试台circuit envelope射频仿真。使用自动生成的模型作为基线设计RF收发器的体系结构，或从库中的块开始。
使用Equivalent Basebandlibrary to quickly estimate the impact of RF phenomena on overall system performance. Design a chain of components and perform single-carrier RF simulation of superheterodyne transceivers, including RF impairments such as noise, impedance mismatches, and odd-order nonlinearity.
使用理想化的基带library to model the system at a higher level of abstraction, further speed up RF simulation, or generate C code for deploying your model.
