It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

The MM5600 is a DPDT DC-20 GHz switch that can operate to 40 Gbps and well suited for differential signal switching. The integrated driver can be controlled by a serial-to-parallel interface that drives the high voltage gate lines of the switches. The design also offers a considerable 94% reduction in size when compared to conventional EM relay solutions. 

At PCIM 2019 last month, imec announced a functional GaN half-bridge monolithically integrated with drivers. The release described how mounted on a buck-convertor test board, the chip converts an input voltage of 48 V to an output voltage of 1 V, with a pulse width modulation signal of 1 MHz. The achievement leverages on imec’s GaN-on-SOI and GaN-on-QST® technology platforms, reducing parasitic inductance and boosting commutation speed.

Industry professionals engaged with Keysight technical experts and executives, and experience live demonstrations May 14 in San Francisco for the first ever Keysight World Americas event. Check out this summary of the event.

eSilicon was in the Samtec booth at DesignCon 2019 presenting their collaboration with Wild River Technology to develop an advanced test system that addresses the difficult signal integrity demands of 56/112G PAM4 operation. The test system design utilizes the upcoming IEEE P370 standard in association with compliance metrics 802.3bs, OIF CEI – 56G PAM4, and COBO to validate the required performance.

Rohde & Schwarz has always been known for high end, very accurate instruments in the high frequency but did you know that R&S has a portfolio of value class instruments with more than 100 products and 300 accessories? From their recent release, here is a summary of the new value instrument additions they highlighted.
