Agilent Technologies' Genesys Software Speeds Sennheiser's High-End Audio Receiver Development
RF and Microwave Design Software Cuts Audio Receiver Development Time by 50 Percent
SANTA CLARA, Calif., Sept. 25, 2009 --
Agilent Technologies Inc. (NYSE: A) today announced that Germany-based Sennheiser has successfully used
Agilent's Genesys RF and microwave design software and Momentum GX electromagnetic (EM) simulator to develop a
series of third-generation, wireless multichannel audio receivers for on-stage professional vocal and musical
developed its high-end receivers of the evolution wireless G3 series, which feature excellent RF sensitivity and
interference immunity, in virtually half the time it would have taken using the company's previous design
methodology. Sennheiser is a world-leading manufacturer of microphones, headphones and wireless transmission
Agilent's Genesys software is an affordable, high-performance RF and microwave tool specifically
created for the RF and microwave circuit board and subsystem designer. Its Momentum GX is a 3D-planar EM simulator
that is fully integrated with Genesys.
Using these solutions, Sennheiser developed tunable high-order filters whose pass bands are synchronized
over a wide tuning range (as defined by the first mixer), without using an input low noise amplifier. EM circuit
co-simulation dramatically reduced the filters' development time by allowing the EM interaction of the filter
layout to be analyzed with the lumped circuit elements using Momentum GX integrated with Genesys' linear and
nonlinear simulators. Genesys' accurate, scalable component library from Modelithics, enabled circuit optimization
during co-simulation to meet exacting performance goals.
Genesys software also enabled Sennheiser to realize a high-end audio receiver series with excellent uniform
sensitivity over a wide tuning range and the superlative adjacent channel interference rejection needed for
multichannel systems. Using Genesys, Sennheiser was able to:
ο define and synthesize the high-order filter
structure with layout implementation;
ο import the actual RF filter layout and simulate with 3D planar EM simulation, via Momentum GX, to account for
all layout interactions;
ο perform EM-circuit co-simulation with circuit optimization for exact
performance goals; and
ο measure and verify the circuit against simulated design goals.
capabilities of Agilent's Genesys and integrated Momentum GX solutions enabled us to effectively address our
toughest design challenges and meet our specs more efficiently - all within half our typical development time,"
said Carsten Bischoff, RF design engineer at Sennheiser R&D in Wennebostel, Germany. "Having the ability to
develop more advanced and novel products, in less time, provides us a key competitive advantage and is crucial to
ensuring we meet the needs of our customers."
"The highly integrated design flow enabled by Genesys significantly reduces design iterations while
minimizing development cost -- key benefits for any RF and microwave designer today," said Gilbert Berger, sales
executive at Agilent's EEsof EDA division in Germany. "We are pleased to provide these benefits to Sennheiser and
to play such a critical role in the launch of its third-generation series multichannel audio receivers."
