Perform MMIC Amplifier S-parameter Measurements
應用說明
RF device Evaluation
To determine RF device performance, design and test engineers generally measure electrical characteristics such as S-parameters, frequency bandwidth, distortion, etc.
Analyzers (network analyzers, spectrum analyzers, etc.) are commonly used to perform these measurements. Since most RF devices do not have an on-chip bias circuit, in addition to an analyzer a voltage or current source is usually required to power and bias the device (in conjunction with a bias resistor). This document outlines how to perform MMIC RF amplifier S-parameter measurements using the Keysight B2961A as the DC bias source.
