Technical Feature Measurement of On-wafer Transistor Noise Parameters Without a Tuner Using Unrestricted Noise Sources This article presents a method for calibrating the four noise parameters of a noise receiver which does not require a tuner. The method permits using general (mismatched) noise sources, which may present very different...

Technical Feature Two-tone vs. Single-tone Measurement of Second-order Nonlinearity Darioush Agahi, William Domino and Nooshin Vakilian Conexant Systems Inc. Newport Beach, CA This article describes how to correctly find the second-order intercept point (IP2) from one- and two-tone tests, and presents measurement results in support of the theory. Relation...

Technical Feature Fixing the Curtice FET Model Convergence difficulties are common in nonlinear analyses of circuits using a Curtice model. The problem is not the model itself, but the limitations of the parameters describing the gate I/V characteristic. In this article, we show why that failure occurs, and how...

Technical Feature Simulating Multi-finger Power HBTs A new model of multi-finger heterojunction bipolar transistors (HBT) is presented to analyze and predict current collapse, bias dependence and output power. The simulation of multi-finger HBTs has proven to be very challenging in both computer-aided design and electromagnetic (EM) simulation. However, by...

New Products COMPONENTS SP4T Switch The model AS204-80 GaAs IC SP4T switch combines high isolation to provide greater sig- nal path separation and reduced RF leakage with non-reflecting ports to eliminate the need for external terminations while providing 50 W output impedance. Covering the frequency range of DC to...
