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 specications 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, rst-pass electronic design success.
Circuit Envelope efciently 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 specications such as error vector magnitude
(EVM), adjacent channel power ratio (ACPR) and bit error rate (BER).
The Circuit Envelope Element capabilities include:
– Circuit Envelope simulation, for efcient analysis of digitally modulated and
transient RF excitation in circuits and systems.
– Accurate circuit simulation of error-vector magnitude (EVM), adjacent channel
power ratio (ACPR), adjacent channel leakage ratio (ACLR), and bit-error-rate
(BER) with specication-compliant 2G, 3G, and 4G modulated RF wireless
signals.
– X-parameter non-linear model simulation under modulated RF excitation.
– Linearizer design guide, providing popular topologies and simulation templates
for designing power amplier linearizer circuits.
– Phase locked loop (PLL) design guide, providing popular topologies and
simulation templates for phase locked loop circuits.
– RF system design guide, providing system architecture design and analysis
utilities and simulation templates for setting up digitally modulated RF sources
and for verication of wireless specications.
– Circuit-system co-simulation when used with the Ptolemy system simulator.
Unlike other envelope simulators, which can only use system behavioral models to
simulate just the envelope of the RF carrier without taking into account impedance
mismatches, Circuit Envelope allows any combination of circuit, system, and
measured X-parameter blocks to be accurately simulated with modulated RF signals
and accounts for signal reflections and frequency mixing throughout the network.
Circuit Envelope takes full advantage of X-parameters, the latest Keysight innovation
that captures full non-linear characteristics from a non-linear vector network
analyzer (NVNA) measurement. It lets you to create accurate non-linear designs,
such as power amplifier linearization and power-added efficiency (PAE) optimization,
under digitally modulated RF excitation with measured X-parameters of off-the-shelf
components. You can’t do this with any other envelope simulator!
