Accurate Measurement of LT5514 Third Order Intermodulation Products &mdash AN97
PDF, 96 Kb, Datei veröffentlicht: Mar 1, 2005
Accurate measurement of the third order intercept point for low distortion IC products such as the LT5514 requires certain precautions to be observed in the test setup and testing procedure. The LT5514 linearity performance is high enough to push the test equipment and test set-up to their limits. A method for accurate measurement of third order intermodulation products, IM3, with standard test equipment is outlined below.

Accurate Measurement of LT5514 Third Order
Intermodulation Products
Dorin Seremeta INTRODUCTION
Accurate measurement of the third order intercept point
for low distortion IC products such as the LT5514 requires
certain precautions to be observed in the test setup and
testing procedure. The LT5514 linearity performance is
high enough to push the test equipment and test set-up to
their limits. A method for accurate measurement of third
order intermodulation products, IM3, with standard test
equipment is outlined below.
It is also important to correctly interpret the LT5514
specification with respect to ROUT, and the impact of
demo-board transmission-line termination loss when
evaluating the linearity performance, as explained in the
LT5514 Datasheet and in Note 1 of this document.
EVALUATION OF LT5514 LINEARITY PERFORMANCE.
The difficulty in providing an adequate low distortion, twotone test signal (Note 2) and failure to adjust the spectrum
analyzer for maximum resolution (Note 3) are the most
common issues when evaluating the LT5514. Below is a
description of a test set-up and a method for evaluating …
