Rogers introduces Kappa™ 438 Laminates as FR-4 alternative

Kappa™ 438 Laminates

Kappa 438 thermoset laminates were developed for wireless circuit designers looking for a better performing and more reliable alternative to FR-4 laminates. These laminates were designed using a glass reinforced hydrocarbon ceramic system that offers superior high frequency performance and low cost circuit fabrication resulting in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes.

Kappa 438 laminates have the UL 94 V-0 flame retardant rating and are lead free solder process compatible, and offer dielectric constants tailored to FR-4 industry standard norms which facilities ease of converting existing FR-4 designs where better electrical performance is needed.

Webinar: Solve your Signal & Power Challenges using SIPro & PIPro

I will be conducting this Webinar on 6th April at 11.00am – 12.30pm (IST). Look forward for your participation.

Keysight Technologies is offering free webinar on 6th April 2017, specifically designed for Signal and Power Integrity Engineers trying to accurately model their printed circuit boards (PCBs), a task that is now more challenging given today’s ever increasing data rates. During the webinar, attendees will learn about SIPro (Signal Integrity Professional) and PIPro (Power Integrity Professional) tools from Keysight Technologies.

SIPro and PIPro provide a cohesive workflow within ADS for signal integrity and power integrity applications in high speed digital board design. Specific use cases will be demonstrated, which will reveal the powerful capabilities of SIPro & PIPro.

Topics to be covered:

– Challenges of increasing speeds & complexity

– Why you need a Channel Simulator

– S Parameters for frequency and time domain data mining

– EM simulation for Signal integrity

– Fast parallel bus DDR4 simulations

– How to Analyze 100 GbE – KP PAM4 vs NRZ

– Power Integrity basics

– Power Integrity IR Drop

mmWave Antenna Design Made Easy in ADS

Thursday, February 2, 2017 11:30 pm, India Time (Mumbai, GMT+05:30)

Thursday, February 2, 2017 10:00 am, Pacific Standard Time (San Francisco, GMT-08:00)

Thursday, February 2, 2017 12:00 pm,  Central Standard Time (Chicago, GMT-06:00)

Why this webcast is important:

For chip designers, planar antennas are easy to integrate. Yet, at millimeter-wave (mmWave) frequencies, new challenges in design and multi-technology integration surface. One such challenge is that at mmWave frequencies, radar applications such as gesture recognition and autonomous vehicles utilize different planar antennas and arrays, and that further complicates an already complex design process. This webcast provides today’s antenna and chip designers an overview on how to easily handle mmWave planar antennas in ADS software for circuit co-simulation. To better illustrate the process and its simplicity, an example of a planar array design at 60 GHz with chip-on-board (CoB) integration is fully explored. Antenna and chip designers will also learn the methodology behind the design process and be presented with multi-technology integration tips.

Design High Q Power Harvesting Circuit Using ADS

The Internet of Things (IoT) fulfills a promise of a more efficient and connected world. But with dozens of devices per household, battery management must become wireless and autonomous. This problem is now being solved through power harvesting, which enables a circuit to power itself from energy in the environment.


  • Design a circuit to harvest enough power for IoT devices of the future and verify simulation results before committing to fabrication


  • Explored the design space for optimum configuration using Keysight ADS Software
  • Transformed the voltage to overcome the Schottky diode junction voltage using a high Q quartz crystal resonator


  • Doubled the usable power
  • Improved conversion efficiency from < 10 to 22.6%
  • Verified a close match between simulation and measurement data
