Reports | No |
New features and changes introduced in this version are:
Use the new snp2smp function to convert N-port S-parameter data and termination impedances to M-port S-parameters.
Use the new circle method to place circles on a Smith® Chart to depict stability regions and display constant gain, noise figure, reflection, and immitance circles.
Use the new powergain function to compute various power gains of a 2-port network.
The smith method now lets you plot the network parameters of devices with more than two ports on a Smith Chart.
Modeling a High-Speed Backplane (Part 1: Measured 16-Port S-Parameters to 4-Port S-Parameters) is the new first part of a four-part demo on "Modeling a High-Speed Backplane." The new demo shows how to extract 4-port S-parameter data from 16-port S-parameter data. The original three parts of the demo are now parts 2, 3, and 4.
The following demos replace the "Designing Impedance Matching Networks" and "Placing Circles on a Smith Chart" demos, respectively, and show how to use the new circle method:
Designing Matching Networks (Part 1: Networks with an LNA and Lumped Elements) uses the available gain design technique to design a low-noise amplifier for a wireless communication system.
Designing Matching Networks (Part 2: Single Stub Transmission Lines) shows how to design input and output matching networks for an amplifier.
