W2301 Circuit Envelope Element
Use the Circuit Envelope simulator in Advanced Design System to analyze transient RF response such as
PLL frequency versus time. You can also simulate digitally modulated RF signals in circuits to analyze digital
wireless speciications such as ACPR and EVM.
The Circuit Envelope Element W2301 provides modulated and transient
RF simulation capabilities to the Advanced Design System (ADS), the
technology and innovation leader in high-frequency mixed-signal electronic
design automation (EDA). It is integrated with Advanced Design System
(ADS), the only design simulation platform that enables the co-design of
IC, package, and board in high-frequency and high-speed applications.
ADS seamlessly integrates system, circuit, and full 3D electromagnetic
simulation with Keysight Technologies, Inc. test instrumentation, resulting
in repeatable, irst-pass electronic design success.
Circuit Envelope eficiently simulates circuits and systems driven under
modulated and transient RF excitation. A patented simulation technology
that overcomes the memory limits of harmonic balance and the time
penalty of transient simulators, Circuit Envelope is especially useful
for creating non-linear designs to satisfy the latest 3G and 4G wireless
standards such as LTE and WiMAXTM. Rather than use steady state
excitation such as with harmonic balance simulation, Circuit Envelope
uses realistic signals containing modulated and transient RF carriers to
accurately simulate wireless speciications such as error vector magnitude
(EVM), adjacent channel power ratio (ACPR) and bit error rate (BER).
The Circuit Envelope Element capabilities include:
