[. . . ] To select this option, use the new Treat Simulink signal as parameter. Enhanced Dielectric Loss Model in Three Transmission Line Blocks The following blocks now provide a more realistic model for dielectric loss: · Coaxial Transmission Line · Two-Wire Transmission Line · Parallel-Plate Transmission Line 7 RF BlocksetTM Release Notes To specify dielectric loss, you use a new parameter, Loss tangent. This parameter replaces the Conductivity in dielectric parameter. Compatibility Considerations Your existing models that include blocks with a nonzero value for the Conductivity in dielectric parameter no longer model dielectric loss. Instead, the models issue a warning message and use the default value of zero for the Loss tangent parameter when you run the model. 8 Version 2. 3 (R2008b) RF BlocksetTM Software Version 2. 3 (R2008b) RF Blockset Software This table summarizes what's new in V2. 3 (R2008b): New Features and Changes Yes Details below Version Compatibility Considerations Yes--Details labeled as Compatibility Considerations, below. Fixed Bugs and Known Problems Bug Reports at Web site Related Documentation at Web Site Printable Release Notes: PDF Current product documentation New features and changes introduced in this version are: · "New Plot Options Added to the Output Port Block" on page 9 · "Enhanced Noise Factor and Noise Temperature Visualization" on page 10 · "Physical Amplifier and Mixer Blocks Now Support Frequency-Dependent, Nonlinear Data" on page 10 · "Enhanced Downconverter Mixers" on page 10 · "Removed GammaMS and GammaML Polar Plot Options" on page 10 New Plot Options Added to the Output Port Block You can plot the following new parameters from the Visualization tab of the Output Port block: · OIP3 for the XY Plot · OIP3, NFactor, and NTemp for the Budget Plot For the definition of each parameter, see "Types of Plots". 9 RF BlocksetTM Release Notes Enhanced Noise Factor and Noise Temperature Visualization You can now plot Noise Factor and Noise Temperature on an XY plot from the Visualization tab of all blocks in the Physical library. Physical Amplifier and Mixer Blocks Now Support Frequency-Dependent, Nonlinear Data You can now specify frequency-dependent nonlinear data on the Nonlinearity Data tab of all physical amplifier and mixer blocks. For more information about how to do this specification, see "Modeling Nonlinearity". Enhanced Downconverter Mixers Mixer blocks now model spectral inversion for down-converter physical mixers. As a result, blocks from the Mixers library no longer error out when you set the Mixer type parameter to Downconverter and the local oscillator frequency (LO) is greater than the input RF frequency. Removed GammaMS and GammaML Polar Plot Options You can no longer display GammaMS and GammaML on a Polar Plot from the Visualization tab of the Output Port block. These parameters are useful for detailed RF analysis, but not for the system-level RF analysis that RF Blockset software supports. In some cases, using RF Blockset software to plot these parameters can lead to incorrect results. Compatibility Considerations Your existing models that plot GammaMS and GammaML will not longer plot these parameters. The library contains these new blocks: · Series R · Series L · Series C · Shunt R · Shunt L · Shunt C These blocks used to be part of the Ladder Filters library and are now part of the Series/Shunt RLC library: · Series RLC · Shunt RLC 13 RF BlocksetTM Release Notes Physical Mixer Block Icons Updated The icons for the blocks in the Mixer library now show the local oscillator that these blocks model. The following blocks have new icons: · General Mixer · S-Parameters Mixer · Y-Parameters Mixer · Z-Parameters Mixer Demos Added and Updated User-Defined Models: Nonlinear Amplifier uses a nonlinear amplifier example to show how to create custom (user-defined) models for RF Blockset software. An Executable Specification for System Design now uses a more realistic model for the front-end filter and provides better instructions for validating the specification. 14 Version 2. 0 (R2007a) RF BlocksetTM Software Version 2. 0 (R2007a) RF Blockset Software This table summarizes what's new in V2. 0 (R2007a): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports at Web site Related Documentation at Web Site No New features and changes introduced in this version are · "Agilent P2D and S2D System-Level Verification Model Support Added" on page 15 · "Dialog Boxes for Physical Blocks Reorganized" on page 16 · "Data File Import Improved" on page 17 · "Noise Specification Options Added" on page 17 · "Nonlinearity Specification Options Added" on page 17 · "Plotting Options Added" on page 17 · "Connection Port Block Added" on page 18 · "Demos Added" on page 18 Agilent P2D and S2D System-Level Verification Model Support Added The General Amplifier and General Mixer blocks now let you import system-level verification models of amplifiers and mixers, respectively, using data from Agilent® P2D and S2D files. Use P2D files to specify the following data for multiple operating conditions, such as temperature and bias values: · Small-signal network parameters · Power-dependent network parameters 15 RF BlocksetTM Release Notes · Noise data · Intermodulation tables Use S2D files to specify the following data for multiple operating conditions: · Small-signal network parameters · Gain compression (1 dB) · Third-order intercept point (IP3) · Power-dependent S21 parameters · Noise data · Intermodulation tables For more information on specifying operating conditions, see "Specifying Operating Conditions". Dialog Boxes for Physical Blocks Reorganized The block dialog boxes of the Physical blocks are now organized by tab. All physical block dialog boxes now contain the following tabs: · Main -- Specify basic block parameters. · Visualization -- Specify plot parameters. In addition, all physical amplifier and mixer blocks contain the following tabs: · Noise data -- Specify thermal noise data. · Nonlinearity Data -- Specify third-order intercept or power data. The General Amplfier and General Mixer block dialog boxes also contain an Operating Conditions tab for specifying operating condition information after you import a P2D or S2D file into a block. For information about the parameters available for a particular block, see the reference page for that block. 16 Version 2. 0 (R2007a) RF BlocksetTM Software Data File Import Improved For blocks that accept data from a file, the new Data file parameter lets you specify the name of the file to import. A new Browse button helps you find the file. Previous versions required you to use the RF Toolbox read function to import the file into the RFCKT object parameter. Noise Specification Options Added For physical amplifier and mixer blocks, the following noise specification options are now available: · Spot noise data imported into the block · Spot noise data in the block dialog box · Noise figure, noise factor, or noise temperature value in the block dialog box For more information on the new noise specification options, see "Modeling Noise". Nonlinearity Specification Options Added For physical amplifier and mixer blocks, the following nonlinearity specification options are now available: · Power data, which consists of output power as a function of input power, imported into the block. · Third-order intercept data, with or without one or more power parameters, in the block dialog box. The power parameters are gain compression power and output saturation power. [. . . ] The dialog box for each block contains the parameters you need to specify the plot. The blockset also provides a composite plot which includes four separate plots in one figure. This predefined combination of plots differs based on the type of block. Data Format Support RF Blockset software supports the Touchstone S2P, Y2P, Z2P, and H2P data file formats. It also introduces the MathWorks AMP format for amplifier data. [. . . ]
