Designing with 4G Modulated Signals for Optimized Multi-standard Transceiver ICs Webcast

1   Hour | Webcast - recorded | Where & When


The demand for mobile communication continues to grow exponentially, leading to sophisticated wireless standards such as LTE-Advanced (4G) and 802.11ac (WLAN). These powerful communications systems make high demands on linearity, bandwidth, and noise performance that are changing the nature of transceiver IC design. Whereas previous design generations have relied on IP3, NF, and Gain based on 1-tone and 2-tone CW tests, it is now crucial to anticipate the true modulated system-level performance, such as EVM, ACPR, and BER, which can vary significantly, depending on the standard.

These specifications are difficult to budget, and require simulation using the actual standard-compliant modulated signals in order to fully capture third order nonlinearities, AM/AM and AM/PM distortions, spectral regrowth, and memory effects. Moreover, the increased bandwidth of Carrier Aggregation drives PAPR to extreme levels, and must be characterized over many operating states and spectrum bands. Optimizing the RFIC design against standard-compliant waveforms and measurements (such as EVM/ACLR in transmitters, or sensitivity/desensitization in receivers), identifies marginal designs earlier, as well as overdesigns that add costly, unnecessary die area or current consumption.

In this webcast, we will demonstrate the importance of designing with modulated signals and how to leverage latest capabilities of GoldenGate at various design phases to optimize your circuit against true system metrics.

Topics discussed include:
• How to leverage pre-configured dedicated RF-system measurements within the RFIC design environment
• Investigate the impact of RF degradation like device mismatch against ACLR and how to make your design more robust by identifying the main contributors
• Close the loop back to the System design team by providing nonlinear behavioral models with memory effects of the RF transmit and/or receive path
• The ability to investigate advanced schemes like Envelope Tracking to achieve improvements in efficiency


If you are designing complex RF circuit blocks and RF transmitters and receivers in highly integrated RFICs targeted for advanced wireless applications like 4G/LTE-Advanced or 802.11ac WLAN, this Webcast is dedicated to you. This webcast will also be of interest to wireless system architects and verifiers who are looking to leverage baseband and RF designs for better system-level insights and sign-off.


Andy Howard, Senior Application Engineer, Agilent Technologies
Andy Howard joined HP in 1985 as a development engineer designing microwave circuits. He spent a year in Japan as a systems engineer before becoming an HP EEsof applications engineer in 1993. His applications work has included simulating noise in nonlinear circuits, high-yield design techniques (design of experiments), Circuit Envelope applications, and for the past fourteen years Agilent ADS, RFDE, and GoldenGate examples. He developed the ADS Amplifier DesignGuide, and also worked on the Mixer DesignGuide. He has extensively updated the ADS Load Pull DesignGuide. He designed a high-speed prescaler IC using Keysight's RFIC Dynamic Link, that was fabricated using IBM's SiGe process. He is the author of the RFIC Flow Workshop. He graduated from U.C. Berkeley, B.S. E.E., 1983, and M.S. E.E., 1985. He was a visiting researcher for one year at NEC's Central Research Labs in Japan while a graduate student, and is fluent in Japanese. He has published a more than 20 magazine articles, HP or Agilent seminar papers, and application notes.
