Two Technologies That Will Enable Next-gen Communication Systems and Instruments

Higher transmission frequencies and modulation rates present new challenges when it comes to system noise, precision timing and noise rejection as well as with compliance with governing industry standards. Tight filtering rejection and precision timing, with ultra-low phase, are critical performance attributes for next-generation systems’ performance.

Overview

With higher demand for bandwidth, transmission in high frequencies and modulation rates present new challenges when it comes to system noise, precision timing, noise rejection and compliance with tighter governing industry standards. 5G Wireless systems operating at sub-6GHz, millimeter wave band or GPS bands require tight filtering rejection along with low power insertion loss in concert with size and design cost for manufacturing. New RF ceramic filter technologies offer great alternatives for large air-cavity filters.

When it comes to timing, the combination of higher modulation bandwidth and transmission frequencies push precision devices to operate at frequencies above 100MHz while phase noise levels are expected to operate at very low levels allowing low noise frequency synthesis to multiply the frequency to higher operating rates. When it comes to imaging applications, high-definition images require low-jitter signal sources to allow high pixel rate image solution.

Key Takeaways

  • Learn fundamentals of RF ceramic filters and circuit integration
  • Understand the importance of selecting a proper filter for the right RF front-end lineup
  • Learn the options available to reduce system noise via HF timing devices with ultra-low phase noise or low noise synthesizer solutions
  • Understand the importance of signal source performance on EVM reduction

Speakers

Roger Merel, Director of Technical Marketing and Business Development for RF Ceramic Filter Products, CTS

Roger Merel has 36 years of experience in the communications systems with 20 years in radio frequency communications for components, systems, and mobile network operator in systems engineering and technical marketing. Roger was the principal system architect for GTE Airfone's digital mobile radio-telephone systems, the first commercial digital mobile radio system deployed in North America which earned him the Leslie H Warner Award. At Scintera Networks, he guided the company to develop the RFPAL (RF Power Amplifier Linearizer) which was the first single-chip solution to use analog-signal processing pre-distortion for linearization of RF power amplifiers. At CTS, he launched new RF Duplexer, Diplexer, and Bandpass Filter product lines, which were the first ceramic filters to support a universal footprint.
